CertainTeed FlintBoard® Pre-Cut Polyisocyanurate Roof Crickets are pre-packaged in triangular sections only (not the entire cricket), each with a right angle to align with CertainTeed's standard 4' x 4' tapered FlintBoard insulation panels. They are available in 1/4" per ft. and 1/2" per ft. slope. Construction variances from building drawings are easily accommodated on site.Technical Information
FlintBoard® Pre-Cut Crickets are specified for use in hot asphalt or coal tar BUR, modified bitumen and single-ply membrane systems. FlintBoard Pre-Cut Crickets are manufactured in a tapered profile to attain positive drainage while maintaining the highest thermal efficiency available in a tapered system.Installation
Before installation begins, the roof deck must be firm, well attached, even, clean and dry.
Do not leave exposed. FlintBoard Crickets is a polyiso organic plastic foam and will burn if exposed to an ignition source of sufficient heat and intensity, or open flame, such as a welder's torch. Do not apply flame directly to FlintBoard roof insulations.
