Wood fiber insulation recovery board is a rigid board product used in some low-slope roofing assemblies as a recover board, substrate, or insulation-related layer.
Why It Matters
Flat and low-slope roof systems depend on the full assembly. The board beneath the membrane can affect attachment, surface smoothness, recover options, and long-term performance.
Common Problems
Common issues include wet or deteriorated board, poor attachment, unsuitable substrate conditions, trapped moisture, and confusing recovery board with all types of roof insulation.
Building Codes & Industry Standards
Wood fiber recovery board should be used according to the roofing manufacturer’s assembly requirements, local code, fire ratings, wind-uplift requirements, and project-specific substrate conditions.
Exterior Echelon Notes
Exterior Echelon reviews low-slope roofing layers carefully because membrane performance depends on what is underneath it.
