Georgia-Pacific DensElement Barrier System Passes the Water Penetration Test
To simulate severe wind-driven rainy weather conditions, three separate wall assemblies utilizing DensElement® Barrier System as the primary water-resistive barrier (WRB) were subjected to high volumes of water on the surface of the wall while simultaneously applying uniform static pressure to the opposite side of the wall for a specified period of time. In all three separate high-pressure water penetration tests, DensElement® Barrier System proved successful in withstanding bulk water with a variety of rainscreen attachment systems.
The same high-stress water penetration tests were conducted on DensElement® Barrier System with Knight Walls ThermaStop System, ECO Cladding Alpha V and Alpha H aluminum brackets, and fiberglass Cascadia Clips.
Considering weather events, changes in temperature, and building movement, it is unlikely that any building will remain 100% weatherproof. But with the right materials and assembly, extra steps can be taken to reduce the risk of damage under both normal and severe weather conditions. With all three assemblies passing the tests, the results showed the ability of each assembly to prevent water from reaching the interior cavity, which demonstrates their capacity to stand strong against potential weather-related water leaks.
