Spray Foam Insulation: Safety Considerations

Closed-cell polyurethane spray foam is amazing stuff. It is considered a great insulator with a higher R-value per inch than almost any other commonly available material. It is mostly preferred because when installed at least an inch thick, it will essentially block water vapor and air movement. Because of these qualities, foam is getting more popular.

Spray foam insulation has its own class level of insulation. It is the only one that requires a supplied air respirator which means no cartridge filter which can protect against the fumes. Once foam is properly cured, most sources show no significant health risks. As heard from other people who are sensitive to odors, improperly cured foam will cause headaches and throat irritations. Even if the foam is properly cured it still has an odor that they detect, however no health concerns appear on material safety data sheets for properly cured foam. It is necessary to provide plenty of ventilation to avoid breathing vapors and mist until the foam has hardened. With this foam insulation, it saves energy and improves comfort because foam is an excellent insulator. It effectively blocks water vapor movement when installed in which the thickness depends on the product that eliminates the need for an additional vapor retarder. Most of all, it is the most straightforward and safest way to insulate existing foundations with a rough surface.

With spray polyurethane foam, it plays a valuable and effective role in helping meet energy efficiency goals. This will act as an air barrier that prevents air leakage and seals cracks and gaps. And the air leaks waste up to 40% of the energy used to heat and cool a single-family home, with spray foam insulation it offers more savings in energy and comfort.
