RM Lucas Company LLC Lucas Tapered Edge Perlite Insulation Board, 1/2 in. to 6 in. Taper, 288 Linear Feet per Bundle
Lucas Tapered Edge Perlite is a tapered rigid insulation board used to create sloped edges in low-slope roofing systems. The listed bundle provides 288 linear feet of 1/2 in. x 6 in. tapered edge perlite board, sold as one bundle. Use it to taper insulation edges where membranes transition at perimeters and penetrations.
Key Features:
- Tapered profile: The board runs from 1/2 in. to 6 in. to form sloped transitions in the roof plane.
- Perlite composition: Perlite board is a rigid mineral insulation commonly used in tapered roof systems.
- Bulk bundle supply: One bundle supplies 288 linear feet of edge board.
- Edge transitions: Ideal for perimeter tapers, crickets and transitions in low-slope assemblies.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
Tapered edge perlite solves the classic problem of a visible insulation edge at membrane terminations by providing a built-in slope. Plan run lengths before ordering since 288 feet per bundle goes a long way, and keep the taper direction consistent with drainage slopes in the field insulation.
Wear gloves and a dust mask when cutting perlite board, and keep bundles dry until installed.
Order Lucas tapered edge perlite insulation board bundles to slope and finish your roof edges.
