Frequently Asked Questions

What is spray foam insulation?

Spray Polyurethane Foam (SPF) is a spray applied plastic that provides insulation while providing an air and moisture barrier for roofs, attics, crawlspaces, walls and basements. Spray Foam is a two-component foam that includes an “A” side of isocyanate and a “B” side of Resin and when combined creates a chemical reaction to make foam. After the chemicals are mixed by a trained professional, the foam is dispensed through professional equipment at high heat as a liquid and expands as it sprayed on to a substrate filling any cracks, gaps and voids. Spray Foam Insulation comes in the form of open and closed cell foams. Open cell foam is a light density half pound foam, that can expand up to 100 times when sprayed and has a sponge like texture. Most open cell foam applications are used in the interior of buildings and provide noise-reduction. Closed cell foam is a medium to high density 2 pound foam that is air and water impermeable. Closed cell foam is used for interior building applications, exterior building applications lifting and has a ridged like texture.

A power source (generator or shore power), a proportioner, a compressor, an air dryer, transfer pumps, a hose and guns. These are main components, but further customizations are available, and our sales representatives will help you find the best equipment for your spraying needs.

The warranty on a spray foam insulation rig varies by manufacture. The typical warranty is one year on all components.

The total average cost, including all necessary components is around $100k. Spray Foam Systems makes low-cost options like our cart setups or our mobile spray rigs that average between $50 – $80k.
