Expert Verdict — Reviewed by the SuperArbor Pro Desk
The 18 in. width suits narrower perimeter transitions than the 24 in. version, letting you match taper reach to deck overhang or cant detail. Keep insulation thickness consistent so the tapered edge lands flush at the membrane line. Bundle coverage of 80 lf makes perimeter takeoff straightforward on smaller roofs.
Wear gloves, eye protection and dust protection when handling and cutting perlite insulation boards.
