PABCO GLASS® Sheathing

Primary Uses

  • Commercial and residential applications
  • Substrate for exterior cladding such as wood, vinyl, or metal siding, shingles, masonry, brick or stucco
  • Can be used with an Exterior Insulation and Finish System (EIFS)

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.

The 1/2” version is used as a single layer application in non-fire rated residential projects.
The 5/8” Type X version is used in commercial applications were fire-rated systems are required. 
  
Made in the USA
