Overview



Ballasted PRMA / Concrete Deck Insulation

In a Ballasted PRMA / Concrete Deck, the ballast, smooth 2” x 2’ x 2’ concrete or stone pavers, holds system in place, and should be installed immediately. Under this, a protective mat is loosely laid between the ballast and FOAMULAR® 404 RB or 604 RB insulation, which is loosely laid over FOAMULAR® 404 or 604, which is also loosely laid, rain channels down, over a nondegradable, bond breaking slip sheet as recommended by the membrane manufacturer. The waterproofing membrane is applied directly to the concrete deck.

FOAMULAR® 404 & 404 RB Extruded Polystyrene Insulation

ASTM C578 Type VI, 40 psi, 1.8 pcf density

FOAMULAR® 404 & 404 RB extruded polystyrene insulations are specially designed for use in Protected Roof Membrane Assemblies (PRMA), where the insulation is placed directly over the membrane. The compressive strength of FOAMULAR® extruded polystyrene insulation provides the integrity needed for long-term roof performance. Extruded polystyrene is the type of insulation recommended for PRMA applications. Owens Corning offers four specific types of FOAMULAR® extruded polystyrene insulation for this use: FOAMULAR® 404 and 604; and FOAMULAR® 404 RB and 604 RB. Both the 404 RB and 604 RB extruded polystyrene insulations feature drainage channels running the length of the panel. These are excellent extruded polystyrene products.

Owens Corning’s FOAMULAR® extruded polystyrene insulation is an ENERGY STAR® qualified product.
