Concrete Roof Insulation PRMA

Protected Roof Membrane Assembly (PRMA) is a simple and effective method concrete roof insulation method while also protecting the waterproof membrane.

Foamular Extruded Polystyrene Insulation is placed directly over the waterproof membrane, providing protection for the membrane, but also creating a continuous thermal barrier on the roof. Foamular is held in place with a specified ballast, usually gravel or concrete pavers.


Good Insulation Pays For Itself

Foamular's high compressive strength means it can easily be walked on once the specified ballast has been installed. This creates an easy space for maintenance crews to access the roof, but can also help create rooftop recreation areas, adding an extra usable space to the building and increasing urban public space.

Extruded Polystyrene is closed-cell insulation, so it minimises potential water absorption. This is vital since water absorption reduces insulation's thermal abilities. Foamular Extruded Polystyrene Insulation requires no additional waterproofing and can easily cope with regular water immersion making it ideal for retro-fitting on older buildings.

The specified ballast can even be a green roof garden, creating a highly green and usable area. Visit our Green Roof Garden page for more information.
