When it Comes to Vinyl Decking, Does Thicker Mean Better?

If you are considering the reliable, low maintenance advantages of sheet vinyl for your deck waterproofing solution, you may be presented with the idea that a thicker vinyl is better waterproof protection for your deck; but that is not necessarily accurate.

With vinyl decking, it is best to refer to building code requirements as your guideline because thicker does not mean better.

When Duradek first started waterproofing decks and balconies, the thickness of the PVC membrane used was only 20 mil, and those decks lasted for several years. Today, the requirement for a vinyl sheet membrane for waterproofing decks and balconies is more than double that at 45 mil.

Pedestrian roof decks however, have a Building Code requirement of 60 mils. That is already 25% thicker than a large commercial grade roofing requirement (48 mils thick). Anything over and above the required 60 mil thickness on decks situated over rated or habitable space does not give you any further waterproof protection. The real difference lies in the installation. In fact, a thicker vinyl can come with disadvantages.

Sheet vinyl comes in rolls, typically between 60-72 inches wide. It is rolled out the length of the deck and installed by adhesion to the deck substrate and by heat-welding the seams where the edges of vinyl meet. The seams are usually ¾” to an inch wide, and it this area of overlap for heat-welding the vinyl seams that an increase in thickness can really be a disadvantage.

Even a 10% difference can be noticeable and make your deck susceptible to things like trapped, ponding water which is something to be avoided with vinyl deck surfaces. Some commercial projects prefer to use an 80 mil vinyl, which is far above building code requirements, but does not give any real added advantage. In fact, that 20 mil difference doubled up at the seam makes a 40 mil difference which is quite noticeable visually as well as by unexpected disadvantages.

Trapped water on a thick 66 mil seam.

Some consideration should be paid to the disadvantages that come with a deck vinyl that exceeds building code thickness.

• Trapped, ponded water.
• Potential tripping hazard.
• Easier to catch seam on snow shovel.
• Difficulties at installation with the fine detailing and handling.

There are actually a number of existing vinyl installations on sundecks from over 30 years ago using 24-32 mil vinyl that are still performing the waterproofing function today. Just a couple of years ago, we pulled up the vinyl from a 32 year old deck that had 32 mil Duradek on it. The plywood, after 32 years, was in perfect shape and was used again as the substrate under a new Duradek vinyl membrane.


This deck in Halifax had 32 year old Duradek vinyl.

When the old Duradek vinyl was lifted,
the plywood underneath was in great shape.

The new Duradek was able to go down over the
existing plywood.

So remember for your project, if you want the advantages of a low-maintenance deck vinyl on an elevated deck, balcony or roof deck, remember that exceeding the building code requirements above 60 mil only provides a thicker seam and no additional waterproof protection.

The reliable protection of vinyl decking is due in large part to the skilled installation techniques of your contractor, and thicker vinyl makes it more difficult to perform the critical details for water-tight protection.

Since these installation skills are so critical, Duradek is available only through one of our trained and authorized Duradek dealers. To talk to an experienced Duradek expert near you, visit our Find A Dealer page or contact us directly for a referral at duradek@duradek.com.

Deck Building Products’ Testing Credentials – 3 Key Considerations

Duradek is proud to offer a building product for your decks that has proven to be reliable in both laboratory testing and actual decking applications in our 40 year history. During those 40 years in use, Duradek has met every single test we must meet to assure you that the products we are offering you meet the building code industry standards.

Since Duradek is both a pedestrian traffic surface as well as a waterproofing membrane, it goes through more than double the testing requirements than either a traffic coating or roofing membrane must undergo independently. These rigorous testing requirements are in place to give you the peace-of-mind that a product as important as one that protects the building envelope of your home is one that you can rely on.

There are few very important factors for you to consider when evaluating a deck building product’s testing credentials:

1 – Is there a 3rd party quality control program in place?

We live in a changing world and what was true a few years ago is not necessarily true today. In some instances, a product has been tested and evaluated as having met building code requirements; but over time manufacturing procedures can change. Duradek is proud to retain the services of Quality Auditing Institute to maintain a 3rd party quality control program. With this quality control program in place, Duradek can confidently assure you that we continually meet the same high standards as we did when our product was tested to show we meet current building code requirements.

2 – Is the product merely listed with an evaluation service or actually tested by the evaluation service?

Some third-party evaluation services offer the option for a Product Listing which is different from a Product Evaluation. While these are presented in a very similar manner, they are quite different.

The major difference between an evaluation report and a listing is that a listing will cover an individual trait that requires compliance with a specific, existing individual standard; where an evaluation will show a review of the product and the multiple traits needed to meet or be an equivalent to what is required in the code; particularly in instances where no specific code exists.”

According to the National Research Council of Canada which governs the CCMC, “An evaluation report is CCMC’s technical opinion on the compliance of a product or system to a code, primarily the National Building Code of Canada (NBC). It applies mainly to innovative products for which there are no specific standards that have been referenced in the code. The product is evaluated as an “alternative” solution. An evaluation listing is a technical statement indicating that a product complies with a specific standard. This service is specific only to products that have standards.”

What is important for you to note in this case when evaluating vinyl deck membranes, is that there is no existing specific standard for 'walkable roofing membranes'. The National Building Codes only acknowledge roofing membranes...there is no sub-group for 'walkable' roofing membranes - yet.  So this is where the evaluation services come in to create criteria that addresses both
1 – a walkable deck membrane; and
2 - a roofing membrane.

Any vinyl deck membrane that offers a CCMC Listing has submitted testing criteria to show it meets requirements of only a roofing membrane which means it was not evaluated as a walkable roof deck membrane. Additionally, a product that is listed does not have to keep a 3rd party quality control program in place.

Duradek Ultra vinyl deck membrane holds a current CCMC Report (CCMC 13134-R) showing that we meet the requirements of BOTH a pedestrian traffic coating and a roofing membrane and is under a third-party Quality Control program.

3 – Is the product evaluation you are reviewing the results for the actual product you are purchasing?

One more thing to be aware of is a basic bait-and-switch tactic where you might be initially presented with product test evaluations for a brand’s premium product, but then you are quoted on a value brand that has not been held to the same high standards. Be sure to verify that the product you are actually getting is the one that has the product testing and evaluations to prove it meets building code requirements.

The Takeaway on Deck Building Products Testing Credentials

While testing and evaluation reports may not be a favorite source of reading material, be sure to carefully review the tests and evaluations when choosing a new building product. Know what the product is tested to meet and know that the test results you review apply to the product you are purchasing.

Most importantly, choose a product that incorporates a 3rd party quality control program to ensure that products tested, and their manufacturing process, maintain consistency for the measure of quality it was evaluated to comply with.

Membrane Roof Covering for Walking Decks - Building Code Requirements

Clarifying the Building Code Specifics for a Walkable Vinyl Roof Deck Membrane

Outdoor living areas have become a popular part of the design of both single family and multi-residential projects. Buyers are a mix of younger families or downsizing empty-nesters – both groups of which are choosing to live in modern designs with little or no maintenance requirements so they have more time to enjoy living. These types of homes often have no space for entertaining friends or family so architects and designers are exploring cost effective ways to open up the home by offering outdoor living spaces like roof decks.

But the IBC has no area that specifically addresses walkable roofing. This can put building officials in a tough spot; code requires a roofing approved product. But when these creative designs come into play and the roof will be used for pedestrian traffic, furniture, hot tubs and the like what should be done? This is the grey area.

Membrane roof coverings are designed, manufactured and tested to withstand direct “service” foot traffic. Slip resistance, and abrasion resistance from sustained loads are not part of a roofing membrane standard’s criteria, but are essential to pedestrian traffic membrane.

Authorities Having Jurisdiction (AHJ)

It is not mandatory that the AHJ use evaluation reports, but rather evaluation reports are there to facilitate a product’s acceptance by an AHJ. ICC-ES evaluation reports remove the burden of determining a product’s proof of Code compliance for its intended use.

ICC-ES Evaluation Report requirements for a membrane roof covering suitable for pedestrian traffic:

The International Code Council (ICC) developed and administers the International Building Code (IBC). ICC Evaluation Services (ICC-ES), a subsidiary of ICC, is an approved agency which provides evaluation reports that can be used to determine if a unique product is suitable for its intended use.

ICC-ES creates acceptance criteria (AC) for products with a similar usage. In the case of Duradek Ultra Roof and Walking Deck membrane it is AC 39 for Walking Decks and AC 75 for Membrane Roof Covering Systems.

Acceptance Criteria (AC) are scrutinized and updated to meet the ever-evolving International Codes.

For a comprehensive overview of the criteria required for AC 39 for Walking Decks and AC 75 for Membrane Roof Covering Systems, here are some great resources put together by Duradek’s technical manager, Len Viegener for your reference:

Building a Deck that Meets Code

While building a deck for your home may seem like a fun, do-it-yourself project, the truth of the matter is that deck construction is a specialty trade. Even general contractors with plenty of building experience may not have the specific knowledge and experience required to construct a structurally safe and attractive deck that meets building code.

There are a number of International Residential Code requirements that are specific to building a safe deck that are not required for most other areas of a home. Decks have two very distinctive and significant contributors to make them such a unique feature requiring special consideration:

1 – The density of occupants on a deck are often far greater than in any other part of the home.

2 – The deck is the only a load-bearing pedestrian surface of a home that is under constant exposure to the elements.

These two factors combined make building codes critical to ensuring the safety of a deck’s future occupants – not just in how the deck is constructed, but also in what materials are used. Whether you are motivated by protecting your family or by reducing potential liability, the following information is critical in building a deck.

The Two Most Important Code Resources for Deck Builders

1 – ICC Approved International Building Code Resource Book

2 – ICC Approved Product Evaluation Reports

International Residential Code (IRC) Reference Book for Deck Building

While the 2015 IRC is complete, many jurisdictions still rely on the 2009 IRC as their standard. Deck builders have the distinct advantage of the availability of a specific Deck Construction Code Book written by one of the industry’s key players, Glenn Mathewson. Glenn Mathewson is an active North America Deck & Railing Association (NADRA) member and is one of the most knowledgeable professionals in the decking industry. He produced the Deck Construction Code Book in partnership with the North America Deck & Railing Association (NADRA) and the International Code Council (ICC).



This specialty reference book takes all decking related code out of the cumbersome 2009 IRC (an 868 page book with decking references in multiple sections) and reduces it down to a concise 270 page decking reference that is much easier for decking professionals to understand. It includes photos and commentary from Mr. Mathewson as well as exact printed reference of the 2009 IRC codes.

International Code Council (ICC) Product Evaluation Reports

Using the right products for your deck building projects is just as important as the construction methods used to ensure a safe and reliable deck. When you are planning your projects and selecting the products to be used, be sure to review a copy of the product’s ICC-ES Report.

When a product has an ICC-ES Report you can see first-hand what specific use(s) for which the product has been evaluated, as well as any products it is used in conjunction with, its installation requirements and what kind of 3rd party testing was conducted to prove its suitability for a particular use.

It is important to note the distinction between an ICC-ES Listed product vs. an ICC-ES Evaluated product which goes through a much more rigorous testing procedure.

Duradek, another industry leader and proud NADRA member, has been around long enough to know the importance of having the performance based ICC-ES Evaluation Report. Duradek’s evaluation (ICC-ES ESR-2151) proves the effectiveness of Duradek’s performance as both a roofing membrane and a pedestrian traffic coating to give our customers the peace-of-mind to know the product will perform as it is intended.

To help our customers and future customers understand and use ICC-ES Reports to their full advantage, Duradek Technical Manager, Len Viegener has produced a couple of easy-to-follow pieces to educate even the most non-technical minded individuals on the value of these reports and how to read them. With a unique product like vinyl deck membranes that does not have its own specific evaluation criteria but instead relies on two distinctly separate evaluated features (in this case, traffic coating and roofing membrane) it is even more important to understand what to look for and why.

The latest document, “Why is an Evaluation Report so Important” breaks down what material standards apply, which building code authority has jurisdiction over those standards and how that leads to the final evaluation report.

The History of ICC

ICC was established in 1994 as a non-profit organization dedicated to developing a single set of comprehensive and coordinated national model construction codes. The founders of ICC are:

• Building Officials and Code Administrators International, Inc. (BOCA)
• International Conference of Building Officials (ICBO)
• Southern Building Code Congress International, Inc. (SBCCI)

Since the early 1900’s, these non-profit organizations developed 3-separate sets of model codes used throughout the U.S. Although regional code development had been effective, the time came for a single set of codes and the three groups created the ICC; and by developing codes without regional limitations, the International Codes. They developed and inventory of comprehensive and coordinated International Codes including the International Building Code (along with 14 others).

• ICC offers unmatched technical, educational and informational products and services in support of the International Codes:
• Code Application Assistance
• Educational Programs
• Certification Programs
• Technical Handbooks and Workbooks
• Plan Review
• Automated Products
• Monthly Magazines and Newsletters
• Publication of Proposed Code Changes
• Training and Informational Videos
• Chapter Locations (350 global chapters)

ICC-ES Providing Peace of Mind to the Construction Industry

For decades, ICC-ES has been the industry leader in performing technical evaluations for code compliance, providing regulators and construction professionals with clear evidence that products comply with codes and standards. Having completed hundreds of evaluations of building products, component, methods and materials, ICC-ES has a proven track record of excellence in product evaluations and customer service. Code officials trust ICC-ES because they know ICC-ES:

• Is compliant to section 1703 of the International Building Code
• Has decades of experience in product evaluations
• Maintains a high quality of evaluation which provides peace of mind knowing they have approved products that comply with requirements of the codes.
• As a subsidiary of the ICC, uses the most up to date and comprehensive info about codes and standards.

Deck Collapse Concerns in Halifax – Inspection or Maintenance Issue?

A deck collapse in Halifax in September reignited the issue of deck safety, building standards and permits. While much study, analysis and debate can surround the issue of deck safety, a simple Google search on deck collapses and the images that come back in the results reveal a consistent common factor…

Most reported decks collapse stories are generated from traditional slotted wood decks that have not been properly waterproofed, built and maintained.

Screen Shot of images from Google search on 'Deck Collapse'.

Cut to the Chase: Reduce Liability with Less Maintenance Time and Cost

What’s Happening to Decks in Halifax?

According to CBC News show, statistics show that one in ten decks fails inspection in the Halifax Regional Municipality, but some experts say the percentage is likely much higher.

HRM's manager of building standards, Matt Covey said, "There's a lot of times we go out and somebody's not building something the way they said they were going to build it and it doesn't meet code.”

Darren Smith, who runs Halifax Home Inspections, says the percentage of faulty decks he sees in the city is considerably higher than the city's estimate.

"I'm saying more like 60 or 70 per cent [of decks are faulty] and I think I'm accurate on that just because it's what I do every day," he says. "Most of the decks built horrible are ones that someone has done themselves."

In September, a third-storey deck collapsed, landing on another deck below during a house party in Halifax's south end, sending six of the seven people occupying it to hospital.

An interesting note is that the deck of the house was part of a controversial addition to the original home in 2002, according to court documents and an article by the now defunct Halifax Daily News.

This precedes the more stringent requirements for all recently build decks brought in by the HRM in 2008.

addition to the original home. (Daily News clipping)

Inspections – Deck Building or Maintenance…who is liable?

According to the Halifax Regional Municipality's bylaws, homeowners have to seek a permit when they construct a new deck or renovate an existing one. Inspectors examine it twice: once before the deck is built and again after the deck is complete.

"Those would be the only inspections unless there was a complaint about an issue on site, or if there was a further change to the existing structure," said Tiffany Chase, a spokesperson for the HRM.

"The ongoing maintenance of those structures and your property as well, really lies with the property owner," said Chase.

"We do say that people should make an annual inspection of their own deck on site, and if you're not sure what to look for then you can hire a professional to come in and do that for you."

Paul Pettipas, the CEO of the Nova Scotia Home Builders' Association, went to the site to see the damage for himself.

"This was a sad state of affairs,” he said. “In my opinion there was no maintenance done on this deck and the landlord's responsible."

The North America Deck and Railing Association (NADRA) is doing its best to reduce the number of deck collapse tragedies and has launched a Deck Safety program that includes a Deck Safety Consumer Checklist for homeowners and a Deck Evaluation Form to assist builders and inspectors in the deck evaluation process.

Reduce Liability with Less Maintenance Time and Cost

Once wood rot has begun, it will gradually grow
until the wood completely deteriorates.

No matter where you live or how carefully constructed your deck is, if it is made of wood, it is vulnerable to wood rot from exposure to moisture. Over time, unprotected wood that begins to rot will gradually deteriorate until it actually crumbles.

That is why waterproof protection is so vitally important to your deck.  It is not just an aesthetic detail…it is a major safety concern.

Six people sent to the hospital is a pretty significant price to pay for neglecting maintenance where an ‘oops, my bad’ simply does not compensate for injury or excuse negligent behavior.

Annual waterproof maintenance can require significant time and cost to maintain which is why Duradek vinyl membranes are such a huge advantage for your outdoor living space. Once a Duradek membrane is installed on your deck, it requires NO maintenance to continue to perform its waterproofing function…it simply does its job.

Last year, Duradek president John Ogilvie joined Duradek’s Atlantic Canada representative, Dennis Dann to visit the job site of a Duradek vinyl replacement when the homeowners wanted to update the look of their home. This particular deck was significant as it was the first deck in Atlantic Canada to have Duradek vinyl installed 30 years prior.

When the old vinyl was pulled off of the deck to make way for the new colour, even Duradek president John Ogilvie was amazed at the incredible condition of the plywood underneath.

The plywood substrate was so well protected that they were able to re-use the original plywood as the foundation for the new Duradek vinyl being installed. 30 years of waterproof protection from a one-time application with a product warrantied for 10 years is a pretty good return on investment for home maintenance.

Home owners and property managers in Halifax may want to reduce their maintenance tasks and risk of liability by discussing their deck waterproofing options with their local Duradek professionals.

Deck Building Items in Consideration for the 2015 IRC

Code Development for Decking in the 2015 IRC

Potential changes in building codes may change the way deck builders are required to construct decks, and certainly something decking professionals should stay informed on. While many jurisdictions have yet to adopt the 2012 edition of the International Residential Code, development of the 2015 IRC is already underway.

The decking industry was represented by building inspector and NADRA advisor Glenn Mathewson at the committee hearings that took place in Dallas in April where nearly two dozen proposed changes that would affect the decking industry were presented. You can see details on the proposed changes at the NADRA website or read an interesting summary with Mr. Mathewson’s analysis on each proposed item in his article 2015 Deck Code Update on Professional Deck Builder.

Here is a quick summary of the status of the proposals affecting deck building for the 2015 IRC:

Comprehensive Proposals

RB264 and RB268 – include joist and beam span tables for wet-use environments, post sizing, framing connection and footing provisions.
Status: Disapproved (however, the committee encouraged stakeholders to modify for the final hearings)

Guards Deflection Limits

RB61-13 - limits guard-post deflection to about 3 inches and limits downward deflection of top rails to about 1 inch over 8 feet while under a maximum required design load of 200 pounds.
Status: Disapproved Height Above Seating

RB145-13 – would change current requirement to measure guards from fixed bench seating at bench level to deck level with built-in deck seating.
Status: Approved (an encouraging indication of common sense in the committee in realizing children can climb moveable deck furniture and allows built-in deck seating to return from virtual extinction!)

Deck Height Measurement

RB143-13 – would change height measurement from current 36 inch horizontal distance from edge of deck back to exact edge of deck in determining whether or not guards are required.
Status: Disapproved (committee agreed that people fall away from an open platform, not straight down….more common sense – go committee!)

Lateral Loads

RB260-13 – would require that the two hold-down tension devices permitted by the IRC be installed within 24 inches of each end of the deck ledger.
Status: Approved

RB261-13 – provides exception to the hold-down device provision for decks less than 30 inches above grade.
Status: Disapproved

RB262-13 – provides for a second lateral load connection method.
Status: Approved

RB263-13 – provides exception for decks not requiring guards.
Status: Approved

Other Structural Requirements

Blocking Over Beams

RB247-13 – would eliminate the requirement for blocking over a beam when joists cantilever 24 inches or less.
Status: Approved with modifications

 

Hangers on Beams and Ledgers

RB253-13 – would restrict design flexibility by such common practices as hanging 2x6 joists from the bottom portion of a 2x12 beam or ledger, with little evidence that minimal loads from conventionally sized lumber joists could split a supporting member.
Status: Disapproved

 

Setbacks

RB66-13 – would provide an exception to fire-resistive construction for decks that are more than 5 feet from the property line or dwelling.
Status: Disapproved

RB74-13 – would require exterior stairways to be at least 5 feet from lot lines and other building on the lot.
Status: Disapproved

RB75-13 – would require accessory structures such as patio covers and decks, whether attached or detached, to be at least 5 feet from lot lines.
Status: Disapproved

 

Other Proposals

RB102-13 – would eliminate all requirements for illumination of exterior stairways.
Status: Disapproved

RB129-13 – clarifies that stairways serving decks, porches, balconies and sunrooms are regulated the same as any other stairway.
Status: Disapproved

RB130-13 – would allow handrails to project up to 6 ½ inches into stairs as opposed to current maximum of 4 ½ inches.
Status: Disapproved

RB141-13 – would allow all ramps other than ones serving a required egress door to be a maximum slope of 1-in8 vs. current maximum of 1-in-12.
Status: Approved

RB142-13 – would require that the minimum width of landings for ramps be equal to the width of the ramp vs. the current 36 inches.
Status: Approved

RB187-13 – would require exterior stairways and ramps built in flood-hazard areas to be constructed in one of three specifically prescribed ways.
Status: Disapproved

RB115-13 – clarifies when safety glazing is required for windows or doors located underneath or at the bottom of a stairway.
Status: Approved

RB42-13 – included exception for decks, sunrooms and similar spaces to the requirement for protection of glazed openings in regions prone to wind-borne debris, provided some specifics regarding the wall of the home are satisfied.
Status: Disapproved

RB8-13 – would require contractors disturbing interior or exterior surfaces on homes built prior to 1978 to submit EPA certificates and a plan complying with 40 CFR745 to building officials for work on homes, even when building a deck.
Status: Disapproved

RB15-13 – restores previous definition of “balcony” and “decks” in the IRC.
Status: Disapproved

RB31-13 – adds a definition for ‘spiral stairway’ in the IRC that allows more freedom than the IBC definition does by omitting the center column from the description.
Status: Approved

RB58-13 – removes references to “guardrail” and replaces them with the IRC-defined term “guard”.
Status: Approved

RB60-13 – included “deck floors” in the floor description for allowable deflection.
Status: Disapproved

RB465-13 – requires that all swimming pools, spas, and hot tubs comply with the International Swimming Pool and Spa Code (this code has deck provisions not currently required by the IRC).
Status: Approved

 

Next Steps in 2015 IRC Code Development

While many of these current results demonstrate a realistic common sense approach and an adequate understanding of the practicalities of deck building practice, any of these results can be overturned at the final hearing. Glen Mathewson will continue to represent the decking industry at the final hearings which are scheduled for October 2013.

With so much effort to ensure decks are built properly, Duradek wants to be sure you use professional waterproofing to make sure it is protected. For information on our vinyl deck waterproofing membrane, contact a trained and authorized Duradek dealer in your area.

The Decking Industry Represented by NADRA at ICC Committee Action Hearings

The decking industry has a voice of representation with the North America Deck and Railing Association (NADRA), and right now is an important time to have that voice heard. On March 11, 2013, the International Code Council (ICC) released proposed changes to the 2012 International Residential Code (IRC). 

Proposed Changes to the 2012 IRC

The ideas for these proposals come from both professionals and non-professionals in all corners of the construction industry, and the decisions made from now until fall on these proposals will directly affect what changes are made to the current codes and effectively become the resulting 2015 IRC...and what the building industry will be working under in 2016 and beyond.

If you are concerned about how these proposed changes will affect the decking industry, now is the time to review the proposals. NADRA Technical Advisor, Glen Mathewson, will represent the decking industry in Dallas at the ICC Committee Action Hearings from April 20th – 31st, where over 2,000 individual proposed changes will be reviewed.

You can view the proposed changes by selecting a pdf from the ICC code development web page link here.

As NADRA members, Duradek extends an invitation to all of our decking industry friends and associates to give us your feedback on the proposed changes, both positive and negative, during the next couple of weeks. We will gather all of your thoughts and insights and provide NADRA with your collective comments to consider for their official position on decking industry representation at the ICC Committee Action Hearings.

ICC Product Evaluation Reports

ICC Product Evaluation Reports are a valuable reference to ensure your building products meet the requirements set out by building codes such as the IRC. For those of us that are not technically minded and do not have a thorough understanding of what ICC codes affect the decking industry, specifically pedestrian traffic coatings, Duradek technical manager Len Viegener has put together The Anatomy of an ICC-ES Report brochure which explains how to read an ICC-ES Report, and includes a pedestrian traffic coating product comparison for what criteria has been met by various products.

Duradek is proud to be the most tested product of its kind and reminds you that All Vinyl is Not Created Equal! Duradek vinyl and Durarail Aluminum Railing Systems are tested to meet IBC and IRC Building Codes, so that you can have confidence in your deck building product selection.

If you’d like to consider using Duradek waterproof vinyl deck surfaces, you can contact a trained and authorized Duradek dealer in your area.

Duradek Assists Understanding of ICC Code Classifications in Deck Waterproofing

While the overall purpose of the ICC (the International Code Council) to provide building industry professionals with the tools needed to ensure public safety in the built environment is the cornerstone for the development of state adopted I-Codes, navigating the waters of the code classifications, requirements and ratings can leave even the most technical minded professionals scratching their heads. 

Interpreting ICC-ES Reports

ICC Evaluation Services provides a reliable and comprehensive method for evaluating building products for code compliance. A valuable reference for architects, specifiers, builders and even home owners to have the peace of mind that the products used in the construction of their project are reliable for their purpose, ICC-ES Reports can authenticate code compliance and provide a method of comparing building product options.

However, with the range of acceptance criteria and testing required for each classification, getting an ‘apples to apples’ comparison is not always a straight forward query. Even when products receive similar testing, there can sometimes seem to be a significant ‘grey area’ to what standards were actually tested.

Duradek Simplifies Comparing Deck Coatings and Coverings Code Compliance

Duradek's Interpretation
and Comparison of ICC Evaluations
for Pedestrian Traffic Coatings

Duradek Technical Manager, Len Viegener performed a detailed analysis of products listed on the ICC-ES website as ‘Pedestrian Traffic Coatings’. In addition to providing a thorough comparison of products in this category, there is a simplified explanation of how to read an ICC-ES Evaluation Report in Duradek’s “The Anatomy of an ICC-ES Report” (2-sided tri-fold, legal sized .pdf). Most of the material included in this brochure is obtained directly from the ICC-ES website, organized to best compare pedestrian traffic coating products. (Please refer to this site for current ICC-ES Report information).

Note: Duradek is classified as a:

• Pedestrian Traffic Coating
• Walking Deck and Classified Roof Covering (AC39)
• Membrane Roof Covering System (AC75)

ICC-ES also provides an instructional video on YouTube on how to read an ICC-ES report that you may find valuable. As muddy as the waters may seem when you start to compare building material evaluation reports, once you really understand what you are truly looking at, you can make much more educated and informed choices in selecting materials for your deck building project needs.

Application of ICC and I-Codes

To ensure projects and building products used meet building code standards, the ICC is a valuable reference point.  50 states and the District of Columbia have adopted the I-Codes at the state or jurisdictional level. While the 2012 I-Codes have been published, most states have yet to adopt them, relying on the 2009 I-Codes. Meanwhile, the ICC-Code Development Schedule is already in progress for the 2015 I-Code edition.

There is a great deal of deck-specific detailing in a proposal in front of the ICC-Code Committee and the North America Deck and Railing Association’s (NADRA) technical advisor, Glen Mathewson will represent NADRA at the ICC hearings. Glen Mathewson is a contributing editor of Professional Deck Builder magazine and you can read his contributions on ICC Codes on the PDB website.

Duradek is the Most Tested Vinyl on the Market Today!

While there are many vinyl products on the market, Duradek is proud to present their testing results for both Canada and the United States to show that Duradek Ultra is the most tested and approved waterproof membrane for use on balconies, decks, patios and roof top decks. Duradek Ultra meets or exceeds the requirements of most North American Building Codes.

If you are comparing vinyl options, be sure to know what to look for in product testing. And remember, no matter how great a product is...it will not perform if it is not installed properly for the best waterproof protection. Duradek Ultra is installed ONLY by our trained and authorized dealers who can be found from coast-to-coast across North America.

Duradek’s Fuzzy Backed Waterproof Vinyl is Backed Up By Third-Party Testing

Duradek’s well-known PVC waterproof membranes are some of the most tested and reliable in the industry. The time-tested woven-backed vinyl membranes of the Duradek Ultra line have a durability and performance reputation that makes it easily one of the most reliable methods of sheet vinyl waterproofing for use on walkable roof-top applications.

While the woven-back Ultra membranes are a reliable and long-lasting waterproofing solution for your decks and balconies, Duradek offers another option for builders who want to complete their waterproofing projects at a slightly lower cost and with the installation convenience of a fuzzy-backed membrane.

Duradek Ultra Okanagan vinyl membranes are the non-woven membrane that also comes with an excellent 10-year waterproofing warranty as the Duradek Ultra line with the woven back. The Duradek Ultra Okanagan is manufactured to the same stringent standards as all Duradek products and is now third-party evaluated as meeting the requirements for use as a walkable roofing membrane.

Quality Auditing Institute (QAI) has determined through an Evaluation Test and Report that the Duradek Ultra Okanagan membrane meets the requirements of CAN/CGSB-37.54-95 standard for “Polyvinyl Chloride (PVC) Roofing and Waterproofing Membrane”. CAN/CGSB-37.54-95 is cited as the applicable standard for PVC single-ply membranes by the National Building Code of Canada, International Building and Residential Codes, ICC-ES Acceptance Criteria, CCMC Technical Guide and Industry Standards.

CAN/CGSB-37.54-95 is a material standard which also provides basis for evaluating PVC membranes used on decking subject to pedestrian traffic. Some of the tests expose the membrane to the severest criteria in the roofing industry.

Duradek Ultra Meets the Requirements of the Florida Building Code

Duradek is one of the most tested PVC waterproof membranes on the market and has shown excellent results in all North American climates. However there are some American climates that operate to a different standard than the rest of the nation. Florida has its own unique environmental challenges, and thus the Florida Building Commission created a unique standard and product approval system – the 2010 Florida Building Code.

2010 Florida Building Code

The state of Florida has a unified code composed of two sections with product approval systems for each section. The state section includes 65 of 67 counties. The High Velocity Hurricane Zone (HVHZ) is geographically defined as Dade county (Miami) and Broward county (Fort Lauderdale) only.
As Florida is a natural disaster prone state, it requires a higher standard for performance of products, materials and systems of construction. The Florida Building Commission (FBC) administers the Florida Product Approval System.

Duradek Ultra Meets the Florida Building Code Requirements

The FBC has determined that Duradek Ultra Roof and Walking Deck Membranes meet the requirements of the 2010 Florida Building Code (except for the HVHZ). Duradek’s submission was reviewed by a state licensed engineer and is under a third-party quality assurance program administered by Quality Auditing Institute Ltd. (QAI).

Duradek Ultra’s Florida Product Approval can be used as a basis for evaluating the suitability for use in other geographical areas that are hurricane prone or have “special wind regions”.

Let the (Safe) Patio Season Begin!

The long-awaited and much anticipated first long-weekend of the summer season is nearly upon us - and not a moment too soon!

Those of us that have decks and patios have been excitedly preparing our favorite outdoor living areas in anticipation of the barbecues, games and luxurious lounging that is sure to follow in the coming summer months.

Having installed over a million square feet of vinyl decking, Duradek wants to be sure that your deck is still the best it can be. While the obvious task of cleaning any organic debris, dirt and soil from the deck surface is usually the first step for many homeowners, be sure to include the critical step of inspecting the waterproofing details such as the caulking around posts and drains.

May is Deck Safety Month ®  

The North America Deck & Railing Association (NADRA) is the decking industry's most visible association, and they have a very strong consumer focus. Deck safety is a critical issue to NADRA, and the organization has a mandate of increasing public awareness of the necessity of regular inspections and maintenance of existing decks, and proper installation of new decks. This initiative prompted NADRA to declare May as Deck Safety Month ® in 2006.

As many decks remain that were installed prior to today's building codes, deck safety is an issue that is important to address and NADRA provides a Deck Safety Consumer Checklist and a Deck Safety Evaluation Form for builders. This is a fantastic free tool for keeping all your deck renovation assessment details together and can be very handy to reference  when getting estimates or discussing project options.

Duradek takes deck safety very serious too. Whether you are located in Canada or the United States, there are building requirements t o consider in constructing your deck surface and preparing the substrate. Right from the initial construction of the deck to the condition of the substrate, the installation of the vinyl waterproof membrane and the installation of the railings, each stage requires its own detailed expertise and is a major factor for Duradek recommending that you do not do the job yourself.

What Is Duradek, You Ask…?

Duradek is the trade name for a line of PVC vinyl membranes that were developed to solve waterproofing problems for sundecks, flat roof decks, balconies and other leisure walking surfaces. The technology was borrowed from the marine industry where PVC was being used to waterproof hull liners for over 25 years. If PVC membrane could perform well in those harsh marine environments, then it can certainly waterproof decks and balconies!

As the industry leader in sheet waterproofing systems, Duradek has been applied to literally billions of square feet of walking surfaces, to protect them from rot, decay and to form a roof over the space below. Now, with over 36 years of waterproofing experience, Duradek is still the primary choice of Architects, Builders, Property Managers and Homeowners who appreciate our attention to detail.

Here is Duradek's current product line-up:

Duradek Ultra – Duradek is the original sheet vinyl designed to waterproof flat decks and roofs. Duradek is textured to provide slip-resistant walking surfaces and comes in a wide variety of colors and patterns to provide a contemporary, clean look previously unavailable in the outdoor waterproof flooring industry. Installed in one easy step and in almost any weather condition, Duradek can be used immediately. Duradek provides the waterproofing and the walking surface in one simple solution.

Duradek Ultra Tiledek – Duradek Ultra Tiledek is identical to Duradek Ultra except the top surface is a fabric top, to which the thinset mortar mix that holds down tile, can tightly adhere to. Installed with the same waterproofing details and techniques as Duradek, Tiledek is the waterproofing roofing membrane under a tile, slate or porcelain finished surface. In addition to protecting the surface below, Tiledek also acts as a crack isolation barrier to bridge small cracks in the substrate preventing those cracks from transferring through to the tile.

Duradek Ultra Plazadek – Duradek Ultra Plazadek is designed specifically for the purpose of waterproofing flat deck or roofs which are intended to have pavers, stamped concrete or a wood/synthetic wood duckboard system placed overtop for pedestrian traffic. Plazadek is identical in construction to Duradek Ultra, installed with the same waterproofing techniques, by the same network of trained applicators and performs the same function of protecting the living space below.

Durarail – Durarail is a powder coated aluminum railing and fencing system produced by Duradek. Constructed with a heavy wall thickness of durable aluminum, the system is exceptionally strong. It enables wider spans between posts and provides for a better visual appearance and view. The TGIC powder coating comes in 8 standard colors, in addition to over 180 custom colors and provides a maintenance free, durable and attractive finish which meets AAMA 2604 and 2605 specifications. The Durarail finish will not rust, peel or corrode even in harsh environments. Durarail is available in many styles, from pickets to view-through glass and is easily customized to satisfy any requirement.

Durarail has systems that meet the rigorous building code standards in both the US and Canada. Additional engineering is available to satisfy even the toughest of code jurisdictions.

A Durarail railing or fencing system is a safe, strong, yet attractive addition to any outdoor living space.
