Home / Services / Glass-Mat Sheathing
Glass-mat gypsum sheathing—like GP DensGlass—resists moisture and mold and is a standard backer for commercial exterior walls. We install it tight, fastened to pattern and detailed at openings so the air and water barrier can go on clean.
Scope
Sheathing is the base for everything on the outside of the wall. We keep boards tight, joints staggered and fasteners flush—not overdriven—so the air barrier, insulation and cladding installers have a flat, sound surface to work on.
DensGlass and equivalent boards on metal or wood framing.
Screws set at the spacing the manufacturer and drawings require.
Clean cuts and edges at windows, doors and transitions.
Crews and lifts sized for long elevations and multi-story walls.
Sequenced with our framing crew so the envelope closes sooner.
