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.

The Cost of Vinyl Decking Promises vs Proven Performance

When evaluating vinyl deck membrane choices before you purchase for your decking project, it is important to consider if you are buying proven performance or potential promises.

While the most important job of vinyl decking is actually waterproofing the deck and protecting the building envelope of the home, nobody wants to be left with an unattractive deck after a couple years of use.

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. And anything under constant exposure to the elements will age to some degree.

Yes, long term results should be taken into consideration...BUT - 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.


Historically, clear protective top coats on deck vinyl have been a real issue and more than one company has had to replace many decks when their clear coat surface failed. In fact, not all companies that went through the experience were able to survive it.

Now once again, some companies are offering a “Scuff Resistant” clear top coat, but it has only been on the market a relatively short time and it offers no Appearance Warranty!!

Since clear top coats have historically been a problem on plastics under constant UV exposure, 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? You enlist the services of an accredited testing agency like Atlas Material Testing Services that perform UV exposure tests to help answer that question.

We've talked a lot about clear top coats over the past couple of years because of our decades of experience and repeatedly witnessing the undesirable results of failed clear top coats. That is because we really want to drive home TWO very important facts.

1 - Accelerated Weather Testing shows that the currently available clear top coats that are in the marketplace today will very likely experience extreme appearance issues.

 

2 - Not all vinyl decking warranties cover appearance issues. In fact, Duradek Ultra 10 year warranties are the only published warranty we can find that specifically covers appearance issues.

 

Compare the three vinyl sample swatches below. One is Duradek and the other two others are other brands of vinyl decking (one that offers a clear top coat). These samples were tested side by side in the same accelerated UV exposure test.

 

Alarming, isn't it? Almost unbelievable, so these products were not just tested once, but twice…

More Vinyl Decking Accelerated UV Aging Testing Results

The images below show a progression of unaltered test results sults of accelerated 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 and an appearance warranty. The 2nd test included multiple product comparisons, and all those with a clear top coat exhibited the same failed results.

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.

Happy Vinyl Decking Customer Shares Story with Duradek

There is nothing more important to any business than a happy customer.

At Duradek, we take pride in the excellent quality of our deck vinyl; and that we have built a brand reputation so reliable that “Duradek” is often used synonymously to describe all vinyl decking.

We also know that no matter how good a vinyl decking product is manufactured, it must be installed with the expertise of a skilled professional trained in the specific details required for effective deck waterproofing to be completely reliable. A unique combination of deck building, roofing and floor laying skills all contribute to the professional installation techniques of a Duradek installer.

It is this combination of a superior product and professional installation that keeps Duradek the leading brand of vinyl decking in North America.

Below is an unedited letter from a recent Duradek customer that details how an unsatisfactory past experience with his deck was able to be turned around when he contacted Duradek. It is summed up nicely with the statement, “The deck is finished and it looks really awesome and I am extremely happy.”, but his story below will tell you why….

Letter to Duradek - September 14, 2015

Good Day and to whom it concerns;

Back in 2014 I contacted your head office and asked for a dealer or installer in my area. I reside in North Bay ON. I was given the name of a Mr. Jim Simpson (at Raildek in Ontario), and this raildekoffice@gmail.com as his e-mail address. I then contacted Mr. Simpson, who sent me to a Mr. Pete Larocque of Deck World North.

Short history, I had a really nice deck built or so I thought, less than 2 years and it was leaking and ruining my house. The other company would not honour their warranty because it was not installed by one of their people, but I bought the product from a store that they sell it at and installed by a person highly recommended by that store. The deck project, which he promised, would be 3 weeks took 15 weeks to finish. First spring it leaked worse than a sieve. So I am somewhat jaded towards contractors. So I called the head office in BC to get a local contractor and that is how I ended up dealing with Mr. Larocque.

When a deck is situated over living space, leaks are unacceptable.

My next and natural question is where do you find these people that you employ and take the time to train into representing your company, they wear your logo on their clothing, they have the logo on their vehicles.

I knew things were not the same as with the other contractor when your people showed up on the correct day, at the correct time and with all their supplies. They also put in a very full long day of work. They did not let a sudden and cold shower slow them down. The second day once again at the correct time and they did a full days work. Third day dawned and they were once more on time, I was impressed. The third day was actually a short day. The deck is finished and it looks really awesome and I am extremely happy.

Duradek Forest Floor vinyl deck installed by Deck World North.

I was somewhat not happy that Mr. Larocque would not let me help and he kept me sitting down. I was not even allowed to tidy up my own deck. He and his partner, Marcel did everything. They both kept telling me to go and watch TV. They left and there was no clean up to do, all the trash and such were removed from the site.

People are quick to call to complain but few are willing to take the time to send a note and say how happy they are with the results of the people employed by anyone, but you folks at Dura Deck should be extremely proud of the way they represent your company by doing an exceptional job, which they did and this will do nothing short to ensure that the reputation of Dura Deck is maintained and broadened. I want to thank Pete and Marcel for going above and beyond the scope of their work and making my deck another room in the house and for their prompt and excellent work. Even if they did not let me do anything.

Mr. Andy R

Thank you, Andy, for sharing your Duradek experience. We hope you enjoy your low-maintenance deck for decades!

For those of you with decking projects on the horizon, before you make your final decision, be sure to talk to a Duradek installer in your area to discover the Duradek difference.

Stamped Concrete Roof Deck Question to Expert Leads to Duradek’s Ultra Tiledek

Home Improvement expert Shell Busey has been advising BC home owners for decades on how to best maintain and improve their homes.  A question on a stamped concrete roof deck was raised this summer and was featured in the Vancouver Province Newspaper Q&A Feature ‘Ask Shell’.

Shell, who is very familiar with roof deck waterproofing solutions from a long relationship with Duradek as one of his House Smart Referral Certified products summed it up succinctly with “…always use Duradek Tiledek.”

Vancouver Province Clipping - June 2015

The Q&A article in Ask Shell “Remedying a leak on stucco”, was as follows:

Q: I have an above-ground deck half over my garage and half over the driveway. The deck has a torch down covering with stamped concrete on top.

The problem is that the deck leaks at the seam where it meets the stucco side of the house.

It is a slow leak, but I do not want to end up having damage to the stucco.

I have put caulking along the seam; it sticks well to the stucco, but not the concrete. Is there a better product I can use?

A: It sounds as though the contractor did not install a metal counter flashing when the deck was built.

A 90-degree metal counter flashing could have been cut into the stucco and placed under the concrete decking to give the best water seal.

You might still be able to have a flashing installed by a professional service trade.

In the meantime, you may want to try a polyurethane caulking, which will stick to both types of surfaces. LePage Quad-max would be a good choice.

(Note: Do not use torch down roofing membrane under concrete; always use Duradek Tiledek.)

Reliable Waterproofing of Tiledek Membranes for Roof Decks Using Pavers

It is a very common scenario that roof decks surfaced with tiles or pavers result in leaks into the home below, but fortunately it is a problem that Tiledek can remedy.

Only a couple of years after Tiledek’s  introduction, TileLetter Magazine featured an article “Waterproofing Makes All The Difference In Dual Level Decks” to show how effectively Tiledek solves leak problems under exterior tile decks.

Like all Duradek membranes, Tiledek is only installed by trained and authorized contractors who are familiar with Duradek’s superior methods of reliable waterproofing. Critical areas like where the deck meets the house are addressed with Detailed Drawings for installers to reference to ensure the building envelope is protected.

In Duradek’s installation best practices, the membrane runs up the vertical wall about 6 inches and is overlapped by the moisture barrier for 2 inches to ensure that the inside perimeter, or “seam” between deck and side of the house, cannot allow any moisture to infiltrate.
