Roxul MonoBoard

Excellent insulation for flat roofing applications

Roxul MonoBoard is a high-density, stone wool commercial insulation board for low slope, new building and re-roofing applications; it can also be used in tapered systems and fabrication.  When used as a coverboard, it provides a suitable substrate for membranes as well as additional thermal resistance.  Additionally, this non-combustible insulation is highly durable and environmentally sustainable.   

It is available as a 1.04” thick board to provide a R4/in at a mean 75°F, which increases at colder temperatures and decreases slightly at warmer temperatures. This can help reduce the thickness of the thermal insulation used in the rest of the roof system.


Stone wool is a combination of slag and basalt.
