STRUCTODEK® HIGH DENSITY Fiberboard Roof Insulation Cover Board With Primed Red Coating
STRUCTODEK® High Density Fiberboard Roof Insulation possesses unique bonding characteristics that ultimately result in superior adhesion capabilities with the current membrane
and adhesive technology on the market today. The unique Primed Red Coating allows for a solid membrane bond while still providing optimal square foot per gallon of adhesive
coverage, thus ensuring a quality and cost-effective membrane installation.
Lightweight, fiberglass free, and cuts with a standard utility knife.
Excellent dimensional stability.
Withstands normal deck traffic during and after construction.
BUR compatible - easily handles hot asphalt.
Good insulating properties.
Primed Red Coating provides optimal surface-bonding characteristics ideal for use in single- and multiple-layer roof systems.
Excellent recover board.
Compatible with most low-VOC, water-based, and traditional adhesives.
STRUCTODEK® High Density with Primed Red Coating can be used as an insulation board, cover board, or reroof/re-cover board. The product is a
high density roofing board designed for low slope single-ply, as well as traditional roof system applications.
It is also widely used as a separation board over existing roofs in recover installations. In recover applications, all wet areas of the old
roof must be removed. All loose and protruding gravel must also be removed.
Properly installed, High Density Fiberboard roof insulation is suitable as a cover board for use under most built-up, modified bitumen and
most single ply roofing systems.
Refer to the membrane manufacturer’s current application and specifications manual for proper installation procedures for fiberboard roof insulation.
Limitations and Potential Fire Hazard
High Density Fiberboard roof insulation is a non-structural, non-load bearing material.
High Density Fiberboard roof insulation should be stored dry and protected from the elements. No more insulation should be installed than can be
covered completely with roofing on the same day.
As unprotected fiberboard will burn, fire safety precautions should be observed whenever fiberboard product is used. Do not expose to open flame or
excessive heat. May smoulder if ignited. If ignited, extinguish completely.
Direct torching of modified bitumen roofing to High Density Fiberboard will present a fire hazard. DO NOT use under torch-applied modified systems.
