Eco-Conscious Consumers Warm Up to Heatlok® Soy Foam Insulation

“Our industry has always focused on energy conservation,” Grant Ostvig, Demilec director of technical service and commercial development, says. “Heatlok spray foam insulation tightly seals a building envelope to improve the energy efficiency of the structure. When you lower the amount of energy used to heat and cool a building, you lower the amount of fossil fuel needed to produce that energy,” he says. “This ultimately reduces the building’s carbon footprint.”

However environmentally conscious consumers are discovering even more benefits of Heatlok spray foam insulation.

Developed with United Soybean Board research support, the Heatlok product line combines recycled plastic bottles and soy polyols to create closed cell, high-performing, high-yield foams with up to 22 percent renewable and recycled content. These features allow architects who choose Heatlok to qualify for up to 10 Leadership in Energy and Environmental Design (LEED) certification points.

In addition to boosting eco-friendly product attributes, soy polyols in Heatlok formulations improve product performance.

In ASTM-E-84 testing – the standard independent test method for surface burning characteristics of building materials – Heatlok XT scored a zero in fire resistance and flame spread.

“We’re constantly developing and testing spray foam products that meet current standards and even anticipate new regulations,” Ostvig says.

Soy-based spray foam innovation and savings extend all the way to application processes.

This year, Demilec introduced Heatlok HFO High Lift, the newest version of the company’s best-selling Heatlok XT, which is designed with Solstice®Liquid Blowing Agent. Solstice complies with Montreal Protocol and has a Global Warming Potential (GWP) of one, which is 99.9 percent less than traditional blowing agents. Heatlok HFO High Lift significantly increases spray ability by allowing up to 6.5 inches of foam to be applied in one pass to achieve an R value of 7.5 per inch. A winter version of Heatlok XT can even be sprayed at temperatures as low as 10 degrees Fahrenheit, which is the lowest in the spray foam industry.
