Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the taper designator (A4, B4, C4, B8) to your tapered insulation layout so slopes continue smoothly across the field. Perlite tapered board is easy to fabricate on site with most roof systems, making it a practical choice for crickets and transitions. Plan the low-to-high transition before ordering so panel counts and taper directions line up.
Handle rigid insulation boards carefully on the roof and keep stacked materials clear of roof edges and openings.
