The Flex Foam is a continuous insulation solution with a low-e aluminum reinforced facing that reduces up to 95 percent of radiant heat transfer. The company provides strong performance to keep buildings cooler in the summer and warmer in the winter for greater efficiency and comfort year-round. Perforated to allow vapor transmission and coated for long term performance and corrosion resistance, Flex Foam provides R 1.6 of continuous insulation and an overall R 4.5 when used with a 3/4-inch enclosed air space. For additional performance, use Flex Foam as part of a system with AA2 or M Shield to achieve an overall R 5.9 and R 6.5 respectively, with 3/4 or 7/8 inch framing.
