Air barrier research shows that 40% of building heat loss can be attributed to air leakage through the building envelope.
Tests for air leakage conducted by an independent laboratory recognized by the CCMC show that POLARFOAM PF-7300-0 SOYA exceeds 500 times the requirements of the National Building Code as an air barrier material.
By creating a sealed air barrier and eliminating air filtration, POLARFOAM PF-7300-0 SOYA does not allow wall condensation that often results in mold, mildew, and wall degradation.
