STYROFOAM CAVITYMATE is an extruded polystyrene foam insulation board with square edges on all four sides. Special 16" width makes it easy to fit between brick ties in cavity wall applications.
Nominal Board Thickness** R-Value† Board Size Edge Treatment Min Compressive Strength
1.0" 5 16" X 96" Square Edge 15 psi
1.5" 7.5 16" X 96" Square Edge 15 psi
2.0" 10 16" X 96" Square Edge 15 psi

Building Code Compliance

Complies with ASTM C 578 Type X. 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.

**Not all product sizes are available in all regions.
† † 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.
