FIBERBOARD ROOFING SUBSTRATE
Completes a Project Reliably and Economically

Durable and dependable, fiberboard roofing substrate helps you stay on top of any roofing application. As basic as a standard built-up roof, yet as current as today's latest single-ply systems, fiberboard is durable and consistent, easy to handle, easy to apply, and lasts for years in both re-roof and new applications.

FEATURES

Dependable
Roof fiberboard's interlocking, high-density wood fibers make installations strong and rigid.

Durable
Count on fiberboard to stand up during:
   • Normal storage
   • Construction handling
   • Roof traffic

Simple
Easy to handle and fast to apply, roof fiberboard:
   • Creates a smooth, even substrate
   • Provides uniform density
   • Offers accurate dimensions

Compatibility
Roof fiberboard provides choices of:
   • Thickness
   • Length/width
   • Surface finishes for modified bitumen, BUR, EPDM, and PVC membranes
   • Factory-applied surface coating to reduce asphalt or adhesive “strike-in”
     when adhered roofing systems are required

APPROVALS
Roof fiberboard manufacturers have obtained approvals from a variety of code and regulatory organizations. Check your supplier approvals.

WARNING
Do not apply flame directly to roof fiberboard. Roof fiberboard may smolder or burn. Extinguish completely if ignited. For specific recommendations, refer to the manufacturer’s application instructions.
