More about this product

 

 

Protected roof membrane assemblies (PRMA) provide high value and long term durability on long life cycle buildings. PRMA roofs range in function from infrequently accessed stone ballasted systems, to paver/plaza deck walking surfaces, to fully landscaped vegetative roof gardens. PRMA extends the life of roofi ng components and reduces building maintenance costs by eliminating UV exposure and minimizing thermal cycling.


 

Because the insulation is installed above the waterproofing membrane and is exposed to water through its service life, resistance to water while maintaining physical properties is critical.

FOAMULAR® 404 and 604 have channels cut into the bottom edges on all four sides of the board to enhance drainage at the board/membrane interface. 

FOAMULAR® 404RB and 604RB have ribs cut into the top surface of the board in addition to the channels on the bottom. The ribs serve as drainage enhancement under pavers when the pavers are laid directly on top of the foam board.
