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.

Duradek Compares Vinyl Decking Warranties
At Duradek, we pride ourselves on having the best warranty in the vinyl decking industry, but we wouldn’t want to be complacent in our assumptions of offering the industry’s best warranty without checking out what other vinyl manufacturers are offering with their warranties from time to time.
We encourage you to do a similar comparison on vinyl decking product warranties before you make your product choice as well. There are several ways that a company can portray that it has a great warranty, but it is up to the homeowner to determine its real value. Don’t be swayed by being sold on a point that really isn’t that important. Similar vinyl products can be vastly different in their performance and their warranties can make that difference even broader still when you read the fine print and ask specific questions.
In evaluating the Product Warranty of 8 vinyl decking manufacturers, in most cases there is some variation of the statement, “The vinyl will be Free of Manufacturing Defects that may results in Leaks”.
Further to this, we noted some insightful questions for you to ask so that you can assess what actual value a vinyl decking product warranty provides to the end-user.
What exactly is the ‘Product Warranty’?
The Product Warranty is relevant only to the actual material and protects you from leaks resulting from a manufacturing defect. Given the nature of pvc (polyvinyl chloride) membranes, once vinyl decking is installed on a deck, any issues resulting from a manufacturing defect would typically be discovered during the first year or two (after the deck has gone through all seasons). If you have not experienced any defects in the material in the first year, you can be fairly confident that the vinyl was manufactured to adequate standards. So whether your vinyl ‘Product Warranty’ term is for 10 years or 15 years makes little difference since any manufacturers defects would be discovered long before the duration of the warranty term.
Does the Vinyl have an ‘Appearance Warranty’?
Since decking products are continually exposed to the elements, there will always be some level of appearance degradation over time, but there can be a big difference in what is considered ‘normal’ aging versus a product with an appearance failure. Most vinyl manufacturers will specifically state that they do not cover any appearance issues. But what happens if your brand new vinyl decking displays an extreme change in appearance over and above normal aging? With many vinyl decking warranties, you have no recourse if your vinyl’s appearance failed but the waterproofing was still performing.
Duradek’s warranty, however, offers 5 years of protection on surface appearance. That provides a higher level of real protection so that homeowners aren’t left with an aesthetically unsatisfying deck surface even if the waterproofing is still intact. Of course, this appearance warranty is applied only to manufacturing issues over and above normal aging and weathering and not resulting from misuse or neglect. If a company is not willing to warranty the appearance of their product, then one should always question, "Why not?".
Does the Vinyl have a ‘Workmanship Warranty’?
Many vinyl deck membranes offer a warranty only on the actual product, but some do offer a limited warranty on workmanship. Vinyl membranes are one of the most superior methods of waterproofing when installed correctly, but shoddy installation and poor details can result in leaks for the homeowner. That is why Duradek is not a do-it-yourself product and is only available as an installed product through trained and authorized dealers. Duradek’s warranty includes a separate workmanship warranty that is dictated by the installation company. Any performance issues resulting from installation can be addressed specifically with the installing company.
If repair or replacement is offered as the Product Warranty solution, is labour included? What about for an Appearance Issue?
Some vinyl decking product warranties allow for repairing or replacing the affected portion of the membrane, but not necessarily the labour required to install the replacement product to complete the repair. Duradek covers the cost of both material and labour on repairing vinyl that has failed due to a manufacturing defect. Further, if a vinyl deck appearance warranty claim was made in the first 2 years of its 5 year term, Duradek would cover the labour costs on that as well (past the 2nd year to the 5th year, the customer would be responsible for the labour on appearance issues).
If a refund is offered as the Product Warranty solution, is it based on what the customer paid, or simply the wholesale cost of the vinyl that the Installation Company paid?
Some vinyl decking manufacturers, particularly the ones that have longer term warranties, offer a refund amount on a failed deck. This refund amount is sometimes a percentage of the cost of the vinyl membrane that decreases each year of the warranty term. So if a vinyl deck membrane were to fail half way through the warranty term, the homeowner may only be provided with half the cost of the vinyl. Not only does that not address the cost of labour to replace the failed deck, but that portion of the vinyl cost can be the wholesale cost of the vinyl to the installing company, not what the homeowner paid. So in the interest in avoiding a lot of boring mathematics, suffice it to say that a refund based warranty, even when covering a 15 year term, does not leave the homeowner with adequate funds to replace the failed deck.
How long has the vinyl decking manufacturer been around? How many warranty cycles has it been through?
When it comes to building products, new does not always mean better. When investing in your home, would you rather take a chance on a new, unproven product or choose a product that has a proven performance history? If a company has been around long enough to have gone through several warranty cycles, they can be confident that their product performs as intended and as their warranty promises. For example, Duradek with a 10 year warranty has been around for over 40 years, and has seen Duradek vinyl perform for 3 times as long as its warranty coverage.
Is the vinyl decking warranty transferable to a new owner?
Most vinyl decking warranties are not transferable to a new owner; however Duradek is proud to stand by its warranty even when the building it is installed on is sold to a new owner. While having a new Duradek deck is something to be enjoyed, it is also a great value-added feature on homes being sold to have a reliable, low-maintenance deck. Duradek honors warranties when the home has been sold (but the new homeowner must be able to provide some documentation of when the work was performed to process any warranty claim).
What are the homeowner’s maintenance responsibilities?
It is important for homeowners to note that most vinyl decking warranties will indicates what maintenance responsibilities must be performed to keep their warranty intact. Similar to automobile warranties, there are some maintenance tasks that if not performed will void a warranty. Homeowners should be prepared to perform cleaning and an annual inspection and maintenance of any sealant (caulking) that applies to their deck.
We found it very interesting to note that several vinyl decking companies had either very little or no public information on their warranty programs, which in itself raises a question.
According to the information we have available, at this date, there are some clear advantages to Duradek’s warranty:
As you can see, the length of the warranty term is only one small factor in what the warranty actually will do for you. If you had a deck that looked like this one below after only a year, we are pretty sure you’d want a vinyl warranty that includes appearance and would cover the installation cost for the replacement.

What’s Really in the Warranty
Overall, the general length of the warranty term does not hold as much relevance to actual protection for the home owner as some of the other restrictions and limitations.We found it very interesting to note that several vinyl decking companies had either very little or no public information on their warranty programs, which in itself raises a question.
According to the information we have available, at this date, there are some clear advantages to Duradek’s warranty:
- Duradek is the Only Company to Offer a Warranty that is Transferable to a New Owner.
- Duradek is the Only Company to Offer an Appearance Warranty.
- Duradek is the Only Company to Cover Labour Costs on Appearance Related Issues (and perhaps even Product Related issues).
- Duradek is the Only Company that has been around for over 4 Warranty Cycles (Over 40 Years).
As you can see, the length of the warranty term is only one small factor in what the warranty actually will do for you. If you had a deck that looked like this one below after only a year, we are pretty sure you’d want a vinyl warranty that includes appearance and would cover the installation cost for the replacement.

Vinyl Decking Product Myths
Debunking the 'Acetone Test' Myth
Duradek, the original vinyl deck membrane, was the only product of its type back when it was first introduced in 1974.
Today there is a large variety of vinyl manufacturers presenting vinyl deck membranes of various widths, thicknesses and styles. And as most of us will agree, Not All Vinyl is Created Equal.
In this competitive environment, there is unfortunately a lot of flim-flam and parlour tricks being presented by some manufacturers to attempt to make their product appear to perform better than the others. When you are building a deck, be sure to chose products that are proven to perform as intended, not just touted to do things unrelated to its actual intended use.
Look at this short video clip where Duradek president, John Ogilvie discusses one of the claims being made in the Acetone Test.
So, how often do you have big containers of Acetone on your deck? The most common household use of acetone is nail polish remover, and as any woman who paints her nails knows, you always put the cap back on your nail polish remover right away to avoid spilling and discolouring any material.
Is withstanding discolouration from an acetone spill really a valid factor in choosing your vinyl deck product?
Is it reasonable to be running around on a deck with a can of acetone? Obviously, not. We feel it's about as 'reasonable' as evaluating your vinyl decking to how it stands up against an Ice Pick Test or a Blow Torch Test...all of which have very little relevance to real-life, day-to-day use of a sundeck. In over 40 years of business, Duradek has never once had an acetone warranty claim.
So don't be persuaded by irrelevant tests. Check the tests that really matter.
The take-away here is that you need to evaluate what is actually important. What really matters in selecting your vinyl decking are these four key points:
When you are choosing your vinyl deck membrane, be sure to select one that has a proven history and a warranty that actually provides some reasonable recourse should the product not perform as promised. With Duradek you can be confident that your deck and your home are protected with style.

Be cautious of competitors using parlour tricks that are used to distract from real issues and meaningful tests, such as Weather Testing (such as accelerated weathering ASTM G-90 shown below).
40 Years in Business and not once, ever have we seen, heard about or handled a complaint about acetone!
