Dense Glass (Georgia-Pacific DensGlass, USG Securock) is a glass mat-faced gypsum panel that eliminates paper facing entirely. The glass mat facing resists moisture penetration and does not support mold growth — making it the preferred substrate for wet areas, exterior sheathing, and high-humidity environments.
Dense Glass products are used as exterior wall sheathing under weather barriers, as tile substrate in showers and wet areas, and as interior panels in high-humidity commercial environments. Smooth installs DensGlass and similar products for both residential and commercial applications throughout the Boston area.
