Demilec, a manufacturer of spray foam products, has released its newest Heatlok closed-cell spray foam insulation product, Heatlok XT, which now contains more than 20 percent renewable and recycled content.
Heatlok XT can now earn commercial and residential construction projects up to 10 LEED certification points.
Since launching its recycled bottle program in 2004, Demilec has recycled more than 300 million plastic bottles into the Heatlok family of closed-cell insulation products, according to Douglas Brady, Demilec vice president of strategic marketing.
Addionally, Heatlok XT’s winter formulation can be sprayed at temperatures as low as 10 degrees F, which Demilec says is the lowest in the spray foam market.
Sprayability has also been increased to save time with a 2-inch-on-2-inch application (within seconds of spraying 2 inches of foam, another 2 inches can be sprayed over the first application) and allow for a wider processing window.
The new Heatlok XT also increased its performance in fire resistance, the company says. In ASTM-E-84 testing, the standard test method for surface burning characteristics of building materials, the Heatlok XT formulation scored a zero in fire resistance and flame spread, meaning that it completely inhibited a flame’s ability to spread from one surface to another.
