NIA 404 Certified Insulation

NIA, the National Insulation Association, published a new standard in 1996 calling for certification of pre-engineered building insulation R-values after lamination. Prior to this standard, there was no method or test to assure what R-value a particular insulation carried; only the measure of width was used to determine an R-value for the unfaced raw fiber glass before lamination. Since lamination can damage the fiber glass and reduce R-values, this is an important distinction. These after lamination R-values are tested by a third party testing facility such as the NAHB Research Laboratories to ensure objectivity.

   Therm-All sells only NIA 404 Certified insulation products. All Therm-All plants have been tested and are certified to produce products meeting the stringent NIA 404 standards for post-laminated R-values. In conjunction with the NIA 404 standard, the fiberglass manufacturers have adopted the NAIMA 202-96 standard for unfaced fiberglass. Therm-All laminates facings to NAIMA 202-96 unfaced insulation to create the NIA 404 improved insulation products. With Therm-All you get what you pay for every time; insist on NIA 404 certified insulation.

Superior Manufacturing

   Therm-All has invested heavily into manufacturing equipment. Our method of laminating a 1:1 ratio of fiber glass to facing is still unequaled in the industry. Competing laminating methods give more facing than fiber glass, resulting in a wrinkled facing application. Only Therm-All can give you 1:1 ratio fiber glass on every machine we use.

   In addition, this equipment is capable of producing the longest rolls in the industry. These long rolls can eliminate roof roll splices that cost time, money, and can potentially create thermal leaks in the building.

   Another innovation is the elimination of the bulge condition where overlap occurs. Metal building insulation is supplied in standard roll lengths from the fiberglass manufacturers. When laminating to a facing, a new roll is added behind the facing when the laminated roll length requirement exceeds the fiberglass roll lengths. Current industry standard is to overlap the fiberglass (figure 1), where Therm-All's standard is to butt the fiberglass together (figure 2).

   If overlap occurs at the purlin or girt when installing the rolls , the overlapping fiberglass must be cut away before installing the sheeting. If the overlap occurs between the purlins or girts it creates a bulge that can be detectable on the interior side of the building. On a 20,000 square foot building, there could be nearly 100 of these overlap splices! Why waste time and money?

   In 1996 Therm-All introduced the first fully-automated laminating machine. The introduction of this machine means that every roll of insulation produced on this equipment is perfectly consistent. Coupled with the 1:1 ratio and the longest rolls in the industry, this is a major step in laminating fiber glass.

With all of these benefits, it's obvious to see why Metal Building Distributors, LLC (MBD) is "hot" on Therm-All insulation.  Ask for a quote today!
