PABCO GLASS® SHEATHING is ideal for commercial and residential applications where the product's performance will not be compromised due to extended exposure. PABCO GLASS® SHEATHING can withstand extended exposure to normal weather conditions*, up to 1 year, during construction. The combination of our proprietary glass fiber reinforced gypsum core encased in our distinctive orange, mold-resistant coated fiberglass mat facing provides added dimensional stability that resists warping, rippling, buckling, and sagging.
