Expert Verdict — Reviewed by the SuperArbor Pro Desk
DensDeck is the industry-standard gypsum coverboard for adding puncture resistance, fire performance, and a smooth adhered surface over polyiso insulation. Use 5/8 in. where higher coverboard performance or wind uplift demands it, and 1/2 in. where budget or height build-up matters. Stagger board joints from insulation joints and follow the membrane manufacturer's fastening or adhesive pattern.
Gypsum boards are heavy; use proper lifting technique and two-person carries for 4 ft. x 8 ft. sheets on roofs.
