Part of the PABCO GLASS® family, PABCO GLASS® SHAFTLINER protects your building from fire, mold and water in a Shaftliner format. 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. PABCO GLASS® SHAFTLINER was developed for lining elevator shafts and constructing light weight fire barriers for cavity shaft walls and Area Separation Walls in commercial and multi-family residential applications. PABCO GLASS® SHAFTLINER can withstand extended exposure to normal weather conditions, up to 1 year, during construction.
