Image Credit Lloyd Alter. It's getting harder and harder to know what to use in green building. Sprayed polyurethane foam is a favourite among green builders because of its high R value and tight seal but the Environmental Protection Agency is raising some questions about its safety. Tristan Roberts at BuildingGreen explains that the issue is Isocyanates such as MDI methylene diphenyl diisocyanate that are chemicals that react with polyols to form polyurethane.

Learn how spray polyurethane foam SPF insulation works.
Home / Homeowners / SPF Insulation Basics. How Does Spray Polyurethane Foam SPF Insulation Work? Spray polyurethane foam SPF is made by mixing and reacting chemicals to create a foam. The mixing and reacting materials react very quickly expanding on contact to create foam that insulates air seals and provides a moisture barrier. SPF insulation is known to resist heat transfer extremely well and it offers a highly effective solution in reducing unwanted air infiltration through cracks seams and joints. There are different types of SPF.

Spray Foam What is Spray Foam Insulation? WhySprayFoam.org.
What is Spray Foam. Spray polyurethane foam SPF is a spray-applied plastic that can form a continuous insulation and air sealing barrier on walls roofs around corners and on all contoured surfaces. It is made by mixing and reacting unique liquid components at the job site to create foam. The liquids react very quickly when mixed expanding on contact to create foam that insulates seals gaps and can form moisture and vapor barriers. SPF insulation is known to resist heat transfer extremely well and it offers a highly effective solution in reducing unwanted air infiltration through cracks seams and joints.

And it's also highly hydrophobic water-repellent. Rigid fiberglass can also be used in this application and it's currently used as part of the Tuff-N-Dri/Warm-N-Dri foundation insulation system. Another option for exterior foundation walls is spray polyurethane foam SPF insulation. I hadn't realized that this was an acceptable application for SPF until my recent research but it's becoming fairly common in Canada and parts of the Upper Midwest in the U.S. Beneath concrete slabs XPS holds nearly 100% of the market today but the use of SPF in this application is growing in Canada. Some insulation contractors use a higher-density SPF formulation in this application the type used for roofs.
