STYROFOAM Ribbed ROOFMATE

CAD Details for STYROFOAM™ Ribbed ROOFMATE™ Specifying Extruded Polystyrene for Protected Membrane Roofing - Guide Spec (14KB PDF) STYROFOAM Ribbed ROOFMATE Product Information Sheet (26KB PDF) STYROFOAM Ribbed ROOFMATE is an extruded polystyrene foam insulation board with 1/2" x 1/4" drainage channels on the bottom long edge of each board. Top surface of the board has ribs that form corrugations in the long dimension of the board. Designed for installation above waterproofing or roofing membranes in protected membrane roof (PMR) applications that incorporate pavers as ballast. Pavers can be installed directly over the ribbed foam surface without the need for pedestals. 10-year limited thermal warranty when installed in the PMR application.

Building Code Compliance

Complies with ASTM C 578 Type VI. Meets IBC/IRC requirements for foam plastic insulation. See ICBO-ES ER 2257, BOCA-ES RR 21-02, NES NER 699, Und. Lab. Inc.™ Classified, see Classification Certificate D369. Factory Mutual Approved - Subject to the conditions of Approval as a roof insulation when installed as described in the current edition of the FM Approval Guide.

**Not all product sizes are available in all regions.
^† R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft2•h•°F/Btu.
^†† Vertical compressive strength is measured at 10% deformation (5% for STYROFOAM PLAZAMATE insulation and for STYROFOAM HIGHLOAD 40, 60 and 100 insulation products) or at yield, whichever occurs first. Since STYROFOAM extruded polystyrene and Dow polyisocyanurate insulation products are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep. For static loads, 3-1 is suggested. For dynamic loads, 5-1 is suggested.
