Johns Manville Tapered FESCO Edge Strip, 0.5 in. x 12 in. x 4 ft. Perlite Cant Board, Brown
JM Tapered FESCO Edge Strip is a high-density laminated cant board made of high-strength cellulosic fibers and expanded perlite, sold as a 0.5 in. x 12 in. x 4 ft. brown strip. It transitions the roof membrane to the nailer or from tapered FESCO panels down to roof level, helping promote positive drainage. One piece per sell unit.
Key Features:
- High-density board: Laminated cant board made of high-strength fibers and expanded perlite.
- Stable insulation value: Expanded perlite provides dimensional stability and insulation value with stable R-value.
- Fire resistance: High perlite content offers far greater fire resistance than conventional wood fiber materials.
- Recycled content: Reinforcing fibers are recycled newsprint; recycled content is third-party certified by UL Environment.
- LEED contribution: Certified recycled content contributes toward LEED Materials credits.
- Positive drainage: Tapered profile transitions membrane to nailer or tapered panels to help promote positive drainage.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
This edge strip is the detail piece that ties tapered insulation transitions back to the nailer while keeping a drainage-positive plane, so plan it into the takeoff alongside your Tapered FESCO or ENRGY 3 field panels. Perlite cant board cuts cleanly with a hand saw, but keep cut edges dry before installation. Its fire resistance and UL Environment-certified recycled content make it a good pick where code and LEED documentation both matter.
Cut perlite board produces dust and sharp edges; wear eye protection, a dust mask, and gloves when cutting and handling.
Order the JM Tapered FESCO Edge Strip 0.5 in. x 12 in. x 4 ft. for clean, drainage-positive roof transitions.
