When using ZIP System wall and roof panels, you will no longer have to worry about the callbacks, cost or liability associated with ripped or torn housewrap or felt. As structural PS-2 rated panels with permanently integrated protective barriers, ZIP System products provides a durable assembly which was engineered to withstand the demands of the job site and to provide long term performance within the building structure. To prove the superior bond between ZIP System wall and roof panels and their protective barrier, we conduct extreme tests.
PS1 Overlay Bond Durability Test
In this test, we boil ZIP System panel specimens for four hours and then place them in an oven for 20 hours. The samples are then subjected to another four hour boiling followed by an attempt to pull the overlay off of the panel. Even after this extreme cycling of heat and moisture loading, the overlay cannot be separated from the underlying panel.
Freeze-Thaw Test
Assembled samples (panel sections joined with tape) are subjected to ten freeze-thaw cycles. Each cycle consists of eight hours drying at high heat, eight hours submersion in water, and then sixteen more hours exposure to sub-zero temperatures. After the testing cycles are completed, samples are reviewed under magnification. ZIP System panels and tape were unaffected by this extreme temperature variation and showed no signs of cracking or delaminating or any other characteristic would affect performance as a water-resistive barrier.
Test Hut
Lab testing is important but we wanted to understand how ZIP System products perform as part of complete roof and wall assemblies in an actual structure. We utilize two test hut facilities in North America that allow us to test our products as part of a system to ensure long term durability and performance. Through thousands of sensors tracking moisture, temperature and weather conditions, we are able to monitor the long-term performance of our products. Through this testing, we see that ZIP System roof and wall provide durability and superior moisture protection needed for the life of a structure.
We’re so confident in the durability of ZIP System roof and wall panels that we back them with a 15-year limited system and a 30-year limited panel warranty.
