Spray Foam Insulation – The Good and the Bad


When properly installed, Spray Pro Insulation makes your home cozy and comfortable. It reduces heat loss in the winter and keeps your air conditioning cool in the summer. It works by sealing the air and reducing energy infiltration, lowering your utility bills and cutting carbon emissions.

But shoddy installation and improper application can cause serious damage, including wood rot and toxic mold. And homeowners have no legal recourse when their homes are damaged by contractors who use low-quality spray foam.

Benefits of Spray Foam Insulation for Your Home

A shortage of qualified installers is a big problem in Vermont and across the country, where Efficiency Vermont reports only about 2,000 homes get weatherized a year when 13,400 need it to meet the state’s climate goals. The shortage is also making it difficult for builders to add spray foam and other high-performance insulation in new construction.

The foam, made of polyurethane or elastomeric resins and blowing agents, is sprayed into wall cavities, attics and crawlspaces to create an effective thermal envelope. The open- and closed-cell foam forms pockets that block the transfer of heat and moisture from one area to another, keeping a building’s interior climate consistent.

In addition to its efficiency, spray foam’s other selling point is that it doesn’t require a separate layer of drywall, which saves time and money during construction. But the plastics used in the foam are not sustainable, which means that when those plastics break down they can release hydrofluorocarbons (HFCs), which have a global warming potential (GWP) of 3,400 times as much as carbon dioxide on a per kilo basis.
