It is Deck Master NZ’s dedication to using only the highest quality waterproofing products that led them to Duradek™ vinyl deck membranes which have been successfully used in North America for over 40 years. Originally conceived by two outdoor enthusiasts inspired by the marine vinyl in their fishing boat (read the Duradek Story for more details), Duradek is the original vinyl decking and essentially created a niche specialty trade.

Having pioneered the vinyl decking industry, Duradek president John Ogilvie was instrumental in establishing North American building codes for the use of Duradek as a roofing membrane, making Duradek the definitive authority on “walkable roofing membranes”. Duradek is also one of the only vinyl decking products that offers an appearance warranty in addition to guaranteeing waterproof performance.

Duradek vinyl recently took the initiative in some extensive product testing above building code requirements and went head to head with competing vinyl brands in accelerated weather testing to clearly demonstrate that Duradek vinyl decking stands up to UV exposure better than any other deck vinyl.

An additional feature that makes Duradek vinyl a superior choice for a deck, balcony or roof deck waterproofing is the fact that Duradek is not available as a retail product for do-it-yourself projects. The team at Duradek knows that no matter how superior a waterproofing product is manufactured; it is the installation details and techniques that ensure the waterproofing performs as intended. This is what made Deck Masters NZ such a perfect fit to become New Zealand’s source for Duradek vinyl decking.

Deck Master NZ already had an existing team of professionals skilled in deck and roof waterproofing and they invested in sending their team representative, Miles Hugill, to Duradek’s headquarters. Located in Surrey, BC (part of the Greater Vancouver Regional District in western Canada), Duradek’s home base is one of the most beautiful, but rainiest climates in North America - a fitting place to perfect waterproofing details. While visiting Duradek headquarters, Miles was busy learning the specific techniques that Duradek has mastered to ensure reliable waterproof performance, which he took back to the team at Deck Master NZ.

The waterproofing specialists at Deck Masters NZ introduced Duradek at the Auckland Home Show in September and have been busy with installations in the Greater Auckland area throughout the summer.

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.

Installation of Duradek vinyl deck membrane.

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.

Vinyl Decking – Understanding the Difference in Backing Types

There are 3 different types of backing for vinyl decking…each with their own unique advantages and disadvantages. If manufactured by a reputable company, each type can have roofing approval and each type is perfectly suitable for your deck.

What is actually more important than the type of backing on the vinyl is the quality of the contractor installing it.

As the saying goes … “A bad Contractor can screw up even the best of products.”

There is a woven cloth backing, a non-woven backing (referred to as fuzzy-backed), and a PVC backed product. A good contractor will be able to do a good job with any of these three backing types.

Characteristics of Each Backing Type

Download “Compare Membrane Backing Options” (296 KB .pdf) for an overview of the following information.

Woven Back – Type 3 (non-embedded fabric) Class B (exposed roofing) Membrane

Adhesion – Adhesive sticks well to woven backing and contact adhesives used allow for a wide window of application in all seasons (but be aware contact adhesives are product specific and not available “off the shelf”).

Heat Welding – Manufactured with a solid color throughout which helps create a solid “bleed out”. The fabric backing melts away to create a strong vinyl-to-vinyl weld. Welding results exceed industry standards, but requires more skill to master installation techniques.

Details – Fabric backing can be removed and vinyl easily manipulated for successful detailing. Standard details are easily attainable without extra preparation or expensive, pre-manufactured details.

Other – Easier to work with in hot weather with a good combination of strength and elasticity. Because skill for installation is mandatory, Duradek (followed by some other manufacturers of woven back vinyl) is only sold to trained contractors, and not available to the general public.

Non-Woven Back – Type 3 (non-embedded fabric) Class B (exposed roofing) Membrane

Adhesion – Adhesive sticks well to fibers, and while adhesive is typically less expensive, this backing can “suck up” the adhesive so will use more, and sometimes excessive glue will cause bubbles.

Heat Welding – Fibers on the backing can be melted off with the heat gun to allow a vinyl-to-vinyl weld and reasonable welds can be achieved by an experienced applicator. Involves a few more steps as the fuzz has to be “buzzed”, and can take a longer time to master the installation techniques.

Details – Without center reinforcement, it is an easier membrane to detail with, but because the fuzz wicks water, you have to remove it or saturate the cut exposed ends at flashings, drains, etc. with glue.

Other – It is usually a less expensive system, but if there is any waterproofing breach in the membrane, water can wick though the fibers (if not properly coated with adhesive) causing rot. Depending on the substrate, repositioning the membrane can be difficult as it will stick like Velcro to rough plywood, when without being glued. In hot weather, the vinyl will “creep” when being smoothed out during application. It is often sold as a “cash & carry” product so available to untrained individuals.

PVC Back – Type 4 (embedded fabric) Class B (exposed roofing) Membrane

Adhesive – Adhesive is typically expensive and there is no second chance if weld area is contaminated with glue. Contact adhesive has a short “working window” making it difficult to use in bad weather or off-season.

Heat Welding – The weld is strong as there is no fabric barrier and it is the easiest to master installation techniques; however different coloured ply makes for bad “bleed out” on welds.

Details – Center reinforced vinyl is more difficult to bend for detailing. Due to the difficulty to adopt to 90˚ bends, PVC metal and pre-made corner boots are required for proper waterproofing detailing.

Other – Because of its conventional “roofing” construction, it is the preferred membrane of some specifiers, but as a deck surface has some disadvantages such as a higher chance of delamination and it is difficult to hide sub-surface blemishes due to the hard surface. Additionally, UV/Mildew inhibitors are only on the top ply where in fabric backed membranes it goes all the way through the PVC.

Top 6 Deck Building Design Features of 2015

Deck building design demands for 2015 highlighted a consistent preference of features for new decks and deck remodels. The most noteworthy deck building products at the 2015 International Builders Show and Deck Expo included features to meet those demands and deck building professionals have no shortage of products to choose from.

In many cases, it takes 2 or 3 different products to meet these design objectives, but Duradek is proud to be able to meet these decking demands in one single product solution.

Colorful
A full range of color options is a desirable feature with many new deck building products releasing a selection of earth tones that harmoniously blend outdoor living space with the surrounding environment.

Duradek has over 26 colors with a range of natural hues from subtle neutral tones to sunset and seaside inspired shades. With a range of patterns, this slip-resistant deck surface brings style to virtually any exterior design scheme.

LIGHTness
Lightweight products have been recognized as environmentally advantageous at the latest builders shows, but not at the expense of durability.

Per square foot coverage of Duradek vinyl decking is a very light weight option, needing just the basic structural load bearing requirements (though extra load-bearing considerations should always be taken into account for deck add-ons like fire or water features, planters and hot tubs).

Duradek has an option to compliment virtually
any outdoor design scheme.

 

Keep it COOL
Thermally treated deck building products are making an appearance with new technologies promising higher fire resistance and temperature insulation; but with all new technologies the practical application has yet to be proven and cost may make some of those options a little prohibitive when compared to alternatives.

Deck surfaces that stay cool on the feet can be achieved with Duradek’s lighter color options. When used on 2nd level decks, Duradek provides roof grade protection and a shaded area below. Sun-lovers can enjoy the upper level deck to bask in the rays, while those less tolerant to UV exposure can enjoy the shaded lower level and still enjoy the outdoors, even in the peak of the afternoon sun.
 

NATURALLY Inspired
Subtle, earthy and aged looks are very popular with low-maintenance, decking products. Beyond simply color tones, the naturally inspired looks for manufactured deck building products imitate their natural counterparts in texture as well with faux wood and stone taking popularity polls.

Duradek was a trend setter early on in these faux-natural favorites with the popular 'Cork' pattern that takes on the texture of real cork, and the unique ‘Forest Floor’ pattern taking on the appearance of fossilized leaves. The latest introductions follow this trend with the ‘Legacy’ line that offers a dynamic aggregate pebble option “Pebble Beach”, or the wood grain looks of ‘Barnwood’ and ‘Driftwood’ that emulate the appearance of aged wood - but without any of the maintenance that real wood requires (see the Pebble Beach press release).

The LEGACY line of vinyl featuring: Pebble Beach,
Barnwood and Driftwood

 

MOISTURE Management
One of the most critical features of deck building is moisture management and there are a variety of options available to incorporate into your deck design. Drip-through deck boards can be enhanced with complex spacer-flange systems or trough systems that route water to gutters; and under deck systems can channel water to gutters, sometimes requiring special joists or underlayment. All of those options include many seams, joins or exposed deck elements that may encounter trapped water. This may provide a dry area below, but is not the best method of ensuring the building envelope or structure of the deck is protected from water infiltration and subsequent wood rot. (see Dry Below Decks Made Easy Part 1 - Trough vs Top | Part 2 - Below vs Above)

Duradek ‘Cork Natural’ vinyl is a low maintenance deck
surface as well as a roofing membrane to keep it dry below.

Duradek is primarily a waterproofing membrane and moisture management system. In fact, Duradek is a classified roofing membrane in addition to being a pedestrian surface. With 40 years of proven waterproofing details and techniques afforded by the quality pvc membrane and pioneering the vinyl decking industry, Duradek provides a dry area below the deck. It protects the critical junctions between deck and structure and eliminates trapped water, deflecting it away from the structure’s points of vulnerability. Duradek allows the water management and attractive walking surface to be addressed in one single product while many other options require 2 or 3 stages of installation.

Duradek vinyl deck membranes provide roof-grade waterproof
protection for a lower patio and dry storage for outdoor items.

 

On the down LOW MAINTENANCE
Homeowners want to do less maintenance on their decks, leaving more time to enjoy it; thus the popularity of manufactured deck building products like composite decking. While composite decking has come a long way in the last decade, it has not been without a myriad of growing pains. Builders and home owners have had to absorb the majority of the cost on failed products as they mature (see When Choosing a Building Product, "New" Does Not Always Mean Better).

Duradek forged the way for low-maintenance manufactured deck building products with its sheet vinyl for waterproofing decks and balconies over 40 years ago. The durable pvc never needs any maintenance or reapplication and will continue to perform its waterproofing function for decades. And unlike many composite products or other vinyl products, Duradek is the only vinyl manufacturer to offer a written appearance warranty to protect home owners from excessive discoloration. While UV exposure will always eventually cause fading over time, Duradek stands up to UV exposure exponentially better than other comparable products and its 5 year appearance warranty backs it up.
 

TRIED and TRUE
After more than 40 years leading the vinyl decking industry, Duradek knows waterproofing details. Because waterproofing details are so critical to the longevity of your deck, Duradek is available only through a network of trained and authorized dealers.

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.

Vinyl Deck – Elasticity vs. Breaking Strength

A good roofing membrane has to be strong enough to withstand stresses and flexible enough to accommodate deck movement.

When you are comparing the properties of vinyl deck membrane options for your deck, you may encounter claims that one vinyl’s ‘Breaking Strength’ is greater than another, followed by claims that a higher rating on Breaking Strength makes it a better option.

Breaking Strength and Elasticity (also called Elongation to Break) are both measured by a tensile testing machine, which pulls a rectangular piece of the vinyl membrane at a constant rate. Breaking strength is the stress needed to break a sample. The elongation-to-break is the strain on a sample when it breaks.

We propose the more important of the 2 tests is Elasticity.

Duradek meets all Breaking Strength and Elongation requirements - it is this elasticity that allows Duradek to perform its waterproofing function for so long (we've seen evidence of our membrane still performing after more than 30 years!...see video below).

Elasticity in a vinyl deck membrane is extremely important.

Imagine your deck as it expands and contracts throughout the seasons as the temperatures change year after year. The deck will be moving and since the membrane is fully adhered, it needs to be able to move with the deck. That requires elasticity, not breaking strength.



So don’t be led to believe that just because one product’s ‘Breaking Strength’ is rated greater than another’s, that that means it is better suited for protecting your deck.

For a great demonstration of elasticity, we love this video from Duradek of Utah that was created to demonstrate Duradek vinyl’s excellent seam strength by towing a Ford F250 truck. This amazing visual shows not only the strength of Duradek’s heat welded seams, but also clearly shows the excellent degree of elasticity in the membrane which is far more than will ever be needed by climate expansion and contraction issues.



When you are selecting a vinyl deck membrane, trust the proven performance of Duradek. Installed only by trained contractors, Duradek makes sure your deck waterproofing performs as intended.

Look for a Duradek installer in your area to discuss your decking project.

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:

Debunking the Vinyl Decking 'Rip Test'

You may encounter some competing vinyl manufacturers performing some demonstrative parlor tricks intended to lead you to believe that one vinyl product is better than another, but we encourage you to see past the flim-flam and look at what is actually important in evaluating a deck vinyl.

Vinyl decking is FULLY adhered to a solid surface, so to be able to take a loose piece off of your deck and tear it is just not realistic at all.

Would that mean it makes sense to show that the thin layers of wood veneer that make up plywood can be torn in half independently, and then claim that makes plywood a product that does not pass the ‘rip test’?

Or does a fabric bandage that can be torn before being applied mean that it does not pass the ‘rip test’ and therefore not suitable to cover a paper cut?

What about latex paint? If you’ve ever had an old can of unused latex paint, you know that when it goes unused and dries to a plasticy, rubbery solid, it can be ripped. Does that mean you have to be worried that when the paint is on your wall, you should be concerned about it ripping?

Of course not. That is ridiculous.

If you are comparing pros and cons on a product, look at factors of its actual use that has some pertinence.



Elasticity is a far more relevant and realistic requirement to address environmental expansion and contraction.

We recommend you look at the Actual test requirements for these products from various building code testing agencies (such as meeting roofing membrane and pedestrian surface requirements), not evaluating based on theatrical demonstrations.

Demand for Outdoor Living Space Creates Development Trend in Vancouver

The increasing demand for outdoor living space is seen all over North America, but cities like Vancouver help drive this trend with its mild climate, gorgeous views and abundance of talented designers, developers and products created specifically to best build a deck.

Local specialty building products like Duradek vinyl deck membranes help to accomplish the ideal outdoor living space with the fundamental of reliable waterproof protection to take care of the practical implications of decks and balconies, but the cascading business effect of this trend reaches landscape architects, builders, designers and artisan craftsmen working with decking, fencing, masonry and retailers with décor.

According to the Vancouver Sun article “Vancouver Home Buyers Fuel Outdoor Living Trend”, one condo developer is even favouring large balconies over space for a dining table and a second bathroom. They key is to make outdoor space livable, regardless of whether it is a single family home or a large multi-residential condo.

“We are seeing the trend affect the architecture in neighbourhoods as well,” said interior designer and project manager Benjamin Simpson, who works largely with west-side Vancouver’s $2 million-plus single-family homes.

“Modern, flat roof construction allows for large rooftop patios that have been a huge selling feature for the spec homes we have designed.” said Simpson, co-owner of Blank Canvas Interiors. Simpson claims that clients used to spend half as much on their exterior budget than indoors but “now it’s almost par,”. Sixty percent of Simpson’s clients now ask for exterior design – five years ago it would have been half that.

Duradek is the foundation of enjoyable outdoor living space.

A product like Duradek vinyl decking is the most fundamental investment for accomplishing this design trend with its roof grade waterproof protection. Duradek is a roofing membrane and walking surface in one, and provides reliable waterproof protection without the need for ongoing maintenance, which is a huge advantage to home owners to save them the cost and time involved in higher maintenance waterproofing systems and deck surfaces.

Vancouver building experts have known and trusted Duradek for decades. Local building celebrity Shell Busey has recommended Duradek vinyl decking from way back on his House Smart television segments, his House Smart Referral Network, and as recently as last month in a Vancouver Province column “Ask Shell”. In this instance, Shell was recommending Duradek’s Tiledek membrane above traditional torch-down products for waterproofing under a stamped concrete roof deck.

In a high-rainfall climate, Vancouver building professionals have to be confident that their waterproofing is handled expertly. That is where Duradek has earned the reputation for reliable waterproof protection. Originating in BC over 40 years ago, Duradek knows the waterproofing and aesthetic value of their decking product…but Duradek also knows that no matter how great a waterproofing product is, it has to be installed correctly to perform as intended. This is why Duradek is only available as an installed product through its network of trained, waterproofing professionals throughout North America.

If you are planning on creating new outdoor living space or renovating an existing deck or balcony, be sure to consult with a Duradek vinyl decking expert before you begin your project….and remember, Not All Vinyl is Created Equal.

NOTE TO THOSE IN THE VANCOUVER, BC AREA:

Be sure to plan to visit Duradek at the fall Vancouver Home & Design Show on October 22-25 in a new location this year at the Vancouver Convention Center West. You’ll find Duradek at booth #122 and it’s a great opportunity to see the latest Duradek patterns and colours first hand and talk to someone about your decking needs. Hope to see you there!

Duradek Expert Talks Decks with Home Improvement Trailblazer Shell Busey

Duradek Cautions on Unproven Deck Building Products Technology

Duradek is very vocal about the truth that ‘new’ isn’t always better…especially when it comes to building products; and now Brad Pitt’s Make It Right Foundation has discovered that basic truth the hard way.

The group built 104 energy-efficient homes in the Hurricane Katrina-ravaged Lower 9th Ward of New Orleans. Dozens of those homes built from 2008 to 2010 included decks and stairs made from TimberSIL, a supposedly glass-infused wood that claimed to provide “an effective barrier in lumber to rot, decay and common wood problems” without using toxic ingredients.

New Product Failure Rates infographic

This ‘new’ product’s lack of chemicals appealed to the Make It Right foundation because of its dedication to “green” building features, but the product performance fell short when premature reports of rot and decay started appearing in 2013...nowhere near the 40 year product guarantee.

As expressed in the New Orleans Advocate, “some local home builders and other non-profit executives said they saw the episode as a cautionary example of the problems facing many in their industry in trying to balance new, cutting-edge technology with time-tested construction techniques.”

The professionals at Duradek couldn’t agree more! We are cautioning builders about a potential similar issue in the niche vinyl decking industry with some manufacturers releasing highly suspect, unproven products into the market. (See Vinyl Deck Membranes Appearance Promises vs. Appearance Warranty).

It is unfortunate that Brad Pitt’s Make It Right Foundation had not chosen the time proven Duradek vinyl deck membranes for these projects. Duradek has a proven 40 year history and has gone through several warranty cycles to be absolutely confident in the Duradek product and installation techniques.

Furthermore, Duradek is also a “green” product and is installed on untreated plywood to avoid the use of harmful chemicals.

Innovation is a great thing, but if you don’t want to gamble on your project and money invested, be sure to use a product that has a proven performance history. To speak to a Duradek professional in your area to bring Duradek’s 40 years of performance to your projects, contact a Duradek dealer in your area.

Appearance Promises of Vinyl Membranes vs. Long Term Protection with a Duradek Warranty

Be cautious when evaluating vinyl deck membrane choices…

Some companies offer a “Scuff Resistant” clear top coat, with No Appearance Warranty!! That's a pretty bold promise with nothing to back it up.

But really, the chance of light scuffing on a well-used deck is the least of your worries if you want a waterproof membrane that will last for decades.

Clear top coats have historically been a problem on plastics under constant UV exposure, but how do you determine how well a product will stand up in 10 years when it has only been on the market half that time?

Accredited testing agencies like Atlas Material Testing Services perform accelerated UV exposure tests to help answer that question.

These unaltered test results below show actual results of UV exposure testing (ASTM G90) of two brands of vinyl deck membranes. The product on top is a vinyl product with a clear top coat.  The vinyl on the bottom is the ‘tried and true’ Duradek membrane with a 40 year history.

Pretty shocking, right?

Almost unbelievable, so the product was not just tested once, but twice…

The 2nd test included multiple product comparisons, and all those with a clear top coat exhibited the same failed results.

All vinyl scuffs to some degree under certain conditions…as does wood, composite deck boards, even concrete. In fact almost everything we walk on scuffs, marks or fades over time. This is the inevitable, realistic result of a ‘wear surface’; particularly with decks under constant exposure to the elements.

However, long term results should be taken into consideration. Be careful not to forgo the long term protection of a proven product with an appearance warranty for short term promises of “scuff resistance” that may have unexpected and unwelcome appearance issues over time.

Make sure you are using a proven product so
you don't get surprises like this.
This deck was originally a light grey and reached a point
where UV rays darkened it completely and quickly.

Railing Systems that Reveal Style, Function and Canadian Innovation

If you have any sort of elevated deck or balcony on your property, guard rails are an absolute essential, but maintaining them does not have to be a high-maintenance chore. You are familiar with Duradek™ as the leading brand of low-maintenance vinyl decking, but you might not be aware that Duradek also offers Durarail™ Aluminum Railing Systems which is another exceptional deck building material option to help you get the most out of the dollars invested in your property maintenance.

Durarail railings are produced locally by Excell Railing Systems Ltd., a proudly Canadian aluminum railing manufacturer that has made its place in a crowded market with quality, durable and attractive standard railing products and bold new product innovations.

Located in Surrey, BC, Excell Railing Systems is home-based in a wet region that benefits greatly from the advantages of its powder coated aluminum deck railing and fencing products. Excell has been in business for over 15 years and has provided aluminum railings throughout continental North America and beyond, including other rainforest regions such as Hawaii and Puerto Rico.

Excell has over 20,000 sq. ft. of manufacturing space and its own powder coating facility that enables timely delivery and a high level of quality control to its customers. All railing systems are engineered to current building codes and are used in a variety of different applications for high-rise, multi residential, commercial and residential applications.

Powder Coating Facility

Excell’s powder coating process ensures that Durarail aluminum railings are completely sealed and protected in a hard finish that is far tougher than conventional paint. The powder coating is electrostatically applied as a free-flowing dry powder and is then cured under heat to allow it to form a “skin”.  This process provides railings that will never rust and will never require sanding or staining. A simple wash brightens them up year after year.

Innovative Railing Options

In addition to its standard picket or glass railing options, Excell is distinguishing itself in a saturated railing market by becoming known for custom aluminum projects and innovative railing solutions. This year, Excell Railing Systems introduces two new, inventive products.

Durarail is proud to present the next generation of topless glass railing systems which is born with the creation of the all-new “Panorama Universal Post”. Excell has taken the advantages and beauty of their existing topless glass Panorama Post system and transformed it into a super-post for a complete “one post does all” system.

Excell Railing Systems president Robert Ogilvie says, “We are very excited to introduce this new topless glass railing system. It is one our most innovative products yet.”

The Panorama Universal Post is an end post, inline post and corner post in one. In addition to this multi-functionality, the Panorama Universal Post also has glass channels with the ability to angle 30 degrees in either direction for a full 60 degree angle variance which is an excellent feature for various design options like uniquely shaped or curved decks.



Panorama Universal Post easily accommodates curved or
custom shaped decks and balconies.

A thicker wall construction allows the Panorama Universal Post to also be used as a divider panel system or a wind wall system; and the glass channel can accept different types of glass or even alternate materials for a louver look.

If those aren’t enough design options for you, the Panorama Universal Post can also accommodate the addition of a top rail cap*, but with a bottomless railing look for your less-obstructed view.  The innovative design of this post offers endless solutions to various railing needs.

The second new addition this year is the “XL Park Rail Top Rail” - a 3 ½” x 2” top rail that can facilitate up to a 3 inch post to fit underneath it in a continuous run. The XL Park Rail Top Rail can also be used with the new Panorama Universal Post and a stock 2-1/2” post allowing for the “beefier wood look” to be achieved. This new top rail is available for both picket and glass systems.

Safety First,...then low maintenance peace-of-mind

The advantages of powder-coated aluminum versus wood railings are very significant when it comes to security. There is no risk of water infiltration or wood rot to weaken the structure which can be a problem with wooden railings that have not been maintained regularly.

Particularly in the summer time when people tend to gather on decks and use the guard rails as leaning posts and group photo locations, you don’t want to risk a structure weakened by water infiltration. Re-painting or re-sealing railing posts each year is far from an ideal solution.

Of course, the fact that Durarail and Excell powder coated aluminum railings do not require any maintenance at all is a huge advantage, particularly in rental properties where building maintenance can be intrusive or inconvenient for tenants. But first on most property owners’ minds is reducing liability. They must have railings that are manufactured to meet building code requirements, meet all safety requirements and have a solid warranty. Of course, the fact that Durarail and Excell railings look great too makes them a complete package and easy choice for new decks or deck renovation projects.

Have an enjoyable and safe summer season on your decks!

Wood Decks Beat Composite Decks for Value in 2015 Cost Vs. Value Report

The Hanley Wood Cost vs Value Report for 2015 confirms that in mid-range projects, Wood Deck additions bring more value to the home than Composite Deck additions.

Wood decks hit the top 5 of home renovation projects that best retain the value of the renovation cost based on resale value of the home. Wood decks at 5th best value with 80.5% cost recouped came in substantially better than a composite deck addition which came in at 14th out of 23 categories with 68.0% of cost recouped according to the Remodeling 2015 Cost vs. Value Report (www.costvsvalue.com).

The 2015 Cost Vs. Value Report compares average cost for 36 popular remodeling projects with the value those projects retain at resale (based on realtors’ perceptions) in 102 U.S. markets . Rising costs with lower rising values ended two years of gains by slipping 3.9-points from last year, but still show the second-best numbers in the past five years. Even though it shows a decline from last year, overall, wood deck additions are still among the best home renovation projects for value retention. On a national average, wood decks have a -7.9% cost-value ratio, with 12 markets showing a 100% return. Composite deck additions show a -8.6% and -9.5% cost-value ratio.

Only five project types saw their cost-value rations rise in this year’s report. Midrange roofing led the way rising 5.9%; and the other four gainers wither the midrange garage door replacement (up 5.6%), the 20-gauge steel replacement entry door (up 5.4%); vinyl siding replacement (up 3.2%) and upscale fiberglass replacement entry door (up 1.7%). The only project on a national basis that pays back more than its investment at resale value was steel entry doors. So when it comes to deck addition projects, wood deck additions consistently retain more value on the home than composite deck additions in all regions and major markets (* See below for breakdown of regional data).

Last week we recommended that in deck renovation projects that you Compare Cost of Maintenance Before You Renovate Your Deck as well as initial costs, and that advice still stands with this Cost vs. Value data.

Even though wood decks traditionally are a high maintenance deck surface often requiring annual labor to maintain its appearance and to be treated for water-resistance, when a wood deck is surfaced with a Duradek vinyl deck membrane it is protected for decades and will not require ongoing maintenance to keep its waterproof performance and thus the security of a safe, stable and attractive deck.

While Composite Decks also do not require any ongoing treatment to stay waterproof, the obvious results of lower retained value of composite decks as shown above may make your low maintenance deck choice an easier one by choosing a wood deck and protecting it with a Duradek membrane. Not only do you gain the low maintenance advantages of a vinyl deck, but if applied on a second level deck, you double your usable space by providing dry space below. While this was not its own category in the Cost vs. Value Report, most realtors will agree that doubling the usable outdoor living space with a long-lasting and low maintenance roof grade membrane will also add to the value of the home.

When you are comparing your options for a deck addition or renovation project, be sure to contact a Duradek installer in your area for an estimate and to learn more of the advantages of using Duradek vinyl deck membranes. When you decide to go with a Duradek deck, be sure to submit photos of your new deck in Duradek's 'Show off Your Deck' contest to win a new tablet!
