Insulation reduces the energy required to heat and cool a building. It can also reduce the potential for condensation occurring on interior surfaces, provide a relatively smooth substrate to which other roofing materials can be applied and has important fire-resistant durability.
Rigid* Isocyanurate Insulation - The most "R" Value per inch.
Isocyanurate Insulation is recommended for hot asphalt or coal tar BUR, modified bitumen and single-ply membrane systems.
Rigid* Fiber Board Insulation - High Density Fiberboard.
Fiber Board Insulation is designed for use as acoustical insulation and as a visual barrier on walls and ceilings where system design requires a rigid product, and where additional strength and abuse resistance are required.
