Expert Verdict Reviewed by the SuperArbor Pro Desk

SecurShield HD Plus CGF is a strong choice when you need cover board-level impact and moisture resistance without sacrificing thermal value; at 1/2 in. it adds R-value where a gypsum board would add almost none. Cut boards with a straightedge and insulation saw for tight perimeter fits, and verify fastener patterns against the membrane system requirements. On slopes steeper than 1:12, confirm system suitability before specifying.

Handle cut edges and panels with care and follow OSHA rooftop fall-protection requirements during installation.
