Spray foam is a composite material formed when two chemicals—isocyanate and polyol resin, typically—react with each other at the tip of a professional-grade spray gun. When sprayed on a surface and fully cured, the foam expands up to 100 times its liquid volume, filling every nook and cranny in a structure to create an air and moisture barrier. This is why it has such a high R-Value and provides top-notch insulation for energy savings, comfort and mold prevention.

Spray foam insulation can be sprayed on a variety of surfaces, from walls to floors to even metal roofing. But before spraying foam, crews will need to prep the area to be sprayed. This could mean moving items out of the way or covering them with plastic if the crew is working in a basement rim joist area. The crew will also need to run a hose to the area and suit up, so they can start spraying.

The Future of Insulation: Unveiling the Power of Spray Foam

While many companies make spray foam insulation, each product is unique. Each contains the same basic ingredients, but different manufacturers use varying percentages of isocyanate and polyol resins to achieve their specific R-Value. The “A” side of a spray foam system, or formulation, contains main liquid components that vary from one manufacturer to another, but the “B” side is usually comprised of polyols, catalysts and blowing agent—and, like the “A” side, each has its own proprietary blend.

While some spray foam formulations contain petroleum-based chemicals, there are many that have been ‘greened’ with replacements such as a non-toxic soy-based blowing agent that does not include HCFCs, which have a GWP (Global Warming Potential) of 2700, or methane, which is 27 to 30 times more potent on the GWP scale than carbon dioxide. Building Energy uses a closed-cell spray foam, HEATLOK SOY, that is both environmentally friendly and has excellent R-Values.
