However, Sigma’s Series 3100 radiant barrier scrim stretched and shifted, but in the machine direction, the threads just would not tear. For traditional heavyweight laminated radiant barrier, this test is sufficient to tear it. For the Tongue Tear strength test, an incision is cut into the radiant barrier and a machine tries to tear it along the cut by ripping and pulling it in separate directions, perpendicular to the plane. These strength tests were then compared to tests run on a conventional heavyweight radiant barrier. US Testing Company, Inc.) measured both the Tongue Tear (ASTM D2261) and the Trapezoid Tear (ASTM D4533) for Sigma’s 3100 Series Radiant Barrier. Strength tests performed by SGS Consumer Testing (a.k.a. Lighter Weight and Still Stronger Than The Competition Sigma Technologies Int’l has created new manufacturing process able to eliminate the wasteful adhesives and films to create a lightweight radiant barrier that is actually stronger than a radiant barrier 50% heavier. It’s an excellent investment for you Fort Worth home.Įnergy Attic's aluminum foil radiant barrier heat insulation helps make homes and offices more energy-efficient, saves money on heating and cooling bills, and reduces the carbon footprint.
