Expert Verdict — Reviewed by the SuperArbor Pro Desk
Install cant strips at every membrane transition where the detail calls for a 45-degree fillet; they reduce stress on base flashing and support insulation field boards. Set them in adhesive or bed them per the roof system spec, and cut strips to scribe around curbs and corners. Perlite is light but crumbly, so handle edges gently.
Perlite dust can be generated when cutting; wear a dust mask and eye protection when cutting cant strips indoors or in still air.
