DensGlass Sheething is the #1 architecturally specified fiberglass that helps add performance and durability. DensGlass is an excellent gypsum sheathing product exactly developed to be moisture  and fire resistant. It’s a solid option that is used in lots of exterior cladding systems including brick, stucco, EIFS and lap siding products. It has a moisture resistant gypsum core and fiberglass exterior mats instead of similar paper faced products. The really nice thing is the manufacturer warranties the product for 12 months exposed to the environment prior to finishing the exterior siding.
