Real-World Proven Performance Through Innovation

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 

R-Value Certification Program

When you buy Owens Corning® Fiberglas™ or mineral wool insulation, you can be confident that what you see on the label is what you get in the package.

Under the NAIMA R-Value Certification Program, Owens Corning participates in voluntary testing to verify the insulating power (R-value) of its fiberglass insulation and mineral wool insulation batts and rolls.

It’s a simple but important step in making sure you get the high quality, proven performance and great value you expect from our insulating solutions.


Simple home insulation solutions that improve the way you live every day.
