Expert Verdict — Reviewed by the SuperArbor Pro Desk
Tapered edge strips eliminate abrupt insulation height changes that telegraph through the membrane; set them wherever the field steps down to metal edges or details. Bed in insulation adhesive or set per the roof system spec, keeping the thin edge toward the transition. Perlite cuts cleanly with a handsaw for fitting around drains and curbs.
Wear a dust mask and eye protection when cutting perlite board, and handle bundles with two people or mechanical help.
