Demilec Raises Industry Bar for Sustainability With Heatlok XT Closed-Cell Spray Foam Insulation

ARLINGTON, TX – October 14, 2015 - Demilec, one of North America’s largest manufacturers of spray foam products, introduces its newest Heatlok closed-cell spray foam insulation product, Heatlok XT. Heatlok XT significantly increases the sustainability of this high-performing product, which now contains more than 20 percent renewable and recycled content. Heatlok XT can now earn commercial and residential construction projects up to ten LEED certification points.

“We are continuously improving and rigorously testing our spray foam products to ensure the highest standards and to achieve sustainable and cost effective solutions. For example, since launching our recycled bottle program in 2004, Demilec has recycled more than 300 million plastic bottles into our Heatlok family of closed-cell insulation products,” said Douglas Brady, Vice President of Strategic Marketing at Demilec.

Heatlok XT yield has increased more than 10 percent over our existing closed cell offerings. With products focused on the spray season, Heatlok XT’s winter formulation can be sprayed at temperatures as low as 10 degrees (F) - the lowest in the spray foam market.

In addition to boosting the product’s eco-friendly attributes and cold-climate temperature range, sprayability has been increased to save time with a 2”-on-2” application (within seconds of spraying two inches of foam, another two 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. 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.
