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.

Strength tests performed by SGS Consumer Testing (a.k.a. US Testing Company, Inc.) measured both the Tongue Tear (ASTM D2261) and the Trapezoid Tear (ASTM D4533) for Sigma’s 3100 Series Radiant Barrier. These strength tests were then compared to tests run on conventional heavyweight radiant barrier. 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. For traditional heavyweight laminated radiant barrier, this test is sufficient to tear it. However, Sigma’s Series 3100 radiant barrier scrim stretched and shifted, but in the machine direction, the threads just would not tear. Because the Trapezoid Tear (ASTM D4533) test pulls the product in the direction of the tear, both types of products will actually tear instead of stretching or shifting. The Trapezoid Tear provides a fair comparison from a tear in one product to a tear in another.

The result of the Trapezoid Tear comparison is that it takes between 2X to 3X more strength to tear Sigma’s thinner, lighter Series 3100 radiant barrier (about 20 lbs per 1000 sq ft roll) than a conventional thick and heavyweight radiant
barrier (about 30 lbs per 1000 sq ft roll). Other manufacturers are still relying on outdated lamination technology, where the only way to add strength is by making the radiant barrier thicker, heavier and more difficult to handle.

Sigma Technologies Int’l has developed the next generation of radiant barrier products by avoiding the use of adhesives and films in the lamination process. Just like the conversion from iron to steel, when waste is eliminated, the resulting product is not only stronger, but but much lighter weight and easier to handle.
