| - | DEXcell FA Glass Mat Roof Board | National Gypsum Company

Division

Gypsum-based roof board with coated fiberglass mat facers and mold-resistant core, used as a substrate board, thermal barrier, or coverboard in commercial roofing assemblies. Coated facer is designed to improve adhesion in fully adhered membrane systems and may eliminate the need for field-applied primer in select assemblies.

applications

Use in low-slope roofing systems including fully adhered, mechanically attached, and ballasted assemblies with single-ply, modified bitumen, fluid-applied, built-up roofing, spray foam, and metal roofs. Functions as a coverboard, thermal barrier, and substrate for vapor retarders and roofing membranes. Also suitable for sheathing at roof-side parapet and penthouse walls.

Limitations

Not intended for prolonged exposure to weather or use as a finished surface. Verify compatibility with membrane type and adhesive requirements; primer elimination is system-dependent. Install as part of a tested and approved roof assembly to achieve required fire-resistance ratings.
