Beaver Plastics Terrafoam HS40 Insulation 2x48x96

2_0765623 MFG #: HS40
TERRAFOAM HS-40 is a high compressive strength board with unusual physical properties. It is inert closed cell expanded polystyrene (E. P. S. ) insulation, with excellent resistance to freeze/thaw, zero capillarity and low moisture absorption. TERRAFOAM HS-40 is a "green" alternative to extruded polystyrene, as it uses no chemical gases that might contrite to global warming or attack the earth's ozone layer. HS-40 will never rot, support mold or mildew and insulating properties do not degrade over time. It's compressive strength is minimum 276 kPa (40 psi)
