Cavity Foam Insulation

- The foam incorporates high-purity graphite granules into the expanded polystyrene (EPS) raw material.
- Each polystyrene granule contains graphite, giving it a silver-gray color and increasing its insulating performance above conventional EPS foam insulation.
- The carbonized foam material reflects radiant heat, lowers the thermal conductivity and improves the insulation capacity.
- Select chambers of the window are thermally enhanced with the precision-contoured foam liners to increase energy efficiency and achieve a lower U-factor.
- U-Factor represents the window’s resistance to heat flow and energy loss–the lower the U-Factor, the greater the energy savings.
- Available in single-hung, double-hung, sliding and picture windows.
