Arlington, Texas - Spray polyurethane foam producer Demilec (USA) llc has launched a new grade, Heatlok Soy 200, as a high energy-efficiency product for attics, that uses recycled plastic materials and soya polyols in its formulation.
Demilec says Heatlok Soy 200, the second Heatlok Soy closed-cell SPF product, has passed the test for an NFPA 286 assembly (AC 377, Appendix X using 7 1" in walls and 11 1" in the ceiling). This means Heatlok Soy 200 can be left exposed in attic and crawl spaces without an ignition barrier or intumescent coating, said Demilec.
A single application of the material provides an engineered building envelope with a high long-term thermal resistance, an excellent air barrier, and a recognised vapour retarder, says Demilec.
Demilec will showcase Heatlok Soy 200 to commercial builders and contractors at the 2010 Sunbelt Builders Show 14-16 Oct 2010 in Grapevine, Texas and nationally at the Greenbuild 2010 trade show 16-18 Nov in Chicago, Illinois.
The formulation for Heatlok Soy 200's closed-cell, rigid SPF insulation contains more than 20 percent recycled plastic materials and soya.
Because it expands to tightly fill the building cavity, SPF creates a healthier, quieter, more energy-efficient environment by sealing cracks, gaps and voids in the building's substrata, said the company. Demilec claims that its energy-efficiency makes Heatlok Soy 200 economical for commercial builders as it means smaller heating and cooling units can be used.
"Heatlok Soy 200 insulation is already proving to be an increasingly important element in creating commercial structures that are energy efficient and environmentally friendly. Just by their mass, commercial buildings offer important opportunities for greatly improving our environment by reducing energy waste," commented Dave Lall, vice president and general manager of Demilec (USA), in the company's 21 Sept statement.
