DensElement® Barrier System is the result of innovative science called AquaKOR™ Technology, which features a proprietary formulation that integrates the gypsum core and the fiberglass mat to form a hydrophobic, monolithic surface that blocks bulk water but allows vapor to pass through. By retaining high permeability, DensElement Barrier System enables moisture to pass through the wall in both directions in any climate. This allows wall assemblies to dry out if they get wet, helping to avoid mildew, mold, and deterioration. Because DensElement Barrier System is a continuous WRB-AB, no separate WRB-AB is needed.
Specifiers can use the system to address fire-, water-, and air-resistance needs with a single product. This innovative 3-in-1 solution eliminates builders’ need to finish the sheathing with a wrap, peel-and-stick, or fluid-applied barrier — greatly reducing misapplication risks.
Because of the complexity of how moisture carried in the air can intrude into the application, there is a common misunderstanding that code only allows for the use of impermeable WRBs in cold climate zones, which may not be the case.
Thanks to its high vapor-permeability (20 perms), DensElement Barrier System offers excellent drying capability. Using a high-perm, fast-drying WRB may
