Inside and out, the first order of GlasRoc® business is protection—whether that’s guarding against the exterior environment or resisting interior moisture and high humidity.

Innovative engineering results in lightweight panels that welcome heavyweight tasks. 

GlasRoc Sheathing and Shaftliner provide that long-term outside coverage; Tile Backer and Interior Drywall double down with protection and superior finishing results.

That’s trustworthy defense, inside and out.
