BUILDING PRODUCTS FOR A BETTER FUTURE

Let’s get started with an announcement! Our Plystik Plus self-adhesive underlayment was recently approved for use with Polyset AH-160 Roof Tile Adhesive. Why is this significant? Well, to understand that, we’ll need to learn a little bit about Polyset’s product and what it means to use an underlayment with a high wind uplift resistance.

Polyset’s Approval

Polyset’s AH-160 Roof Tile Adhesive is exactly that—an adhesive system designed to adhere clay and concrete tiles to rooftops. In order to install this product, roofers need to choose an underlayment from a short list of approved materials. There are a couple caveats to this choice, too. In areas that experience high winds, usage of non-adhesive underlayment is restricted. Specifically, if a region exceeds 100 mile per hour basic wind speeds, then installers must use a self-adhered underlayment like Plystik Plus beneath the Polyset.

One of the reasons why Plystik received approval? Because in addition to passing long-term heat and humidity aging tests along with meeting the tensile strength requirements, Plystik features higher wind uplift resistance non-adhesive underlayments.

Why High Wind Uplift Resistance is Crucial

An underlayment with high wind uplift resistance can save hundreds or thousands of dollars’ worth of damage during severe weather events. The problem with underlayments that are nailed or stapled into place is that they can’t be fixed completely flush to the roof deck, which means that wind can work beneath them, lift them from the surface, and eventually rip the underlayment off. In addition to the lost roofing material, this leaves the wood deck beneath exposed to rain and the elements, which can create leaks. Over time, leaks can lead to structural damage within the building beneath.

Self-adhered products like Plystik have a much higher wind uplift resistance rating because there are no air pockets beneath these products. Because the underlayment seals to the roof, wind can’t catch it as easily, which means it offers much more protection during high wind events.

Other Benefits of Plystik Plus

Plystik comes with numerous other benefits in addition to higher uplift resistance. It’s a 48-mil underlayment with a unique design that gives it fantastic tear resistance. Even if high winds do remove the roof covering, Plystik is less likely to tear than thinner underlayments.

Part of the reason why Plystik has such high uplift resistance is because it provides excellent adhesion to the roof’s surface. Whether installed over wood or metal, it forms a tight bond without air pockets, which means that once in place, it’ll stay put.

With this, Plystik performs very well even in extreme temperatures—as proven by Polyset’s testing. This underlayment is rated to provide good adherence and protection between temperatures of -40° all the way up to 260° Fahrenheit.

And those are just a few of the benefits Epilay’s Plystik Plus has to offer! To learn more about how this product revolutionizes roofing systems, feel free to check out our product pages or get in touch with us to ask questions and request samples.
