Heatlok XT closed-cell spray foam insulation increases the sustainability of this high-performing product, which now contains more than 20 percent renewable and recycled content. The product’s winter formulation can be sprayed at temperatures as low as 10 degrees Fahrenheit. 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 inch-on-2 inch application. In ASTM-E-84 testing, the standard test method for surface burning characteristics of building materials, the 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.
