PRMA - Protected Roof Membrane Assembly - Concrete Roof Insulation
PRMA – (Protected Roof Membrane assembly) is a simple and effective method of insulating flat concrete roofs while also protecting the waterproof membrane.
Foamular Extruded Polystyrene 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 In Energy Savings”
Foamulars 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 also can 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 insulations thermal abilities. Foamular Extruded Polystyrene 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.

CDOP 4 is the newest building in the prestigious Coronation Drive Office Park. The $100 million building is owned jointly by AMP and Sunsuper and is located on the fringe of Brisbane CBD offering panoramic views of the Brisbane River and CBD skyline.
DFW Airport has undergone some extensive renovations, including a review of its PRMA system. After 17 years in some of the most extreme environments, 88% of the Foamular was re-used, saving thousands on labour and new material costs.
PRMA (Protected Roof Membrane Assembly) is a popular way to construct large commercial and public buildings. The concrete roof is waterproofed and then Extruded Polystyrene is placed over it, wrapping the roof in a continuous thermal barrier. This method not only provides superior insulation values, it also protects the roof membrane, giving the building a longer life span.
