Advantages and Disadvantages of Spray Foam Insulation

Spray foam insulation is applied to the walls, roof, and attic of new construction or existing homes, pole barns, and commercial buildings. It creates a tight, airtight envelope that stops the transfer of heat from the interior to the outside in the winter and vice versa in the summer. It also prevents moisture from causing mold and wood rot.

Unlike other types of insulation, such as fiberglass and cellulose, spray foam does not deteriorate over time. It can last for the lifetime of your building. It does not compress or sag and is non-toxic when cured. The material is sprayed into place from a hose or gun and is made of two chemicals that meet at the tip. The A side contains isocyanate – which sounds scary, but it’s also the main ingredient in Gorilla Glue! It reacts with the B side of spray foam, which is a mix of polyol resins, catalysts, blowing agents, and a measure of fire retardant.

One of the biggest advantages is that it helps prevent condensation on the exterior of your home, which is a major cause of ice dams in the winter. Spray foam also keeps heat from escaping through gaps in your buildings envelope.

However, some of the early “green” spray foams contain blowing agents with a high global warming potential (GWP). These can off-gas into your home over time, even with a ventilation system. Some manufacturers have started to use low-GWP blowing agents, which are much safer.
