Spray polyurethane foam (SPF) insulation has grown in popularity in large part because it is so good at keeping homes warm in winter and cool in summer.
Some Benefits of SPF in homes
- Increases comfort
- Impedes entry of insects and pests where it is applied
- Minimizes air infiltration that can generate condensation and result in mold growth
- Seals small cracks to help insulate large areas, such as walls and roofs
- Resists settling due to its general stability
- Can qualify for utility rebates, tax credits and green certification

Because it is sprayed directly into the gaps, cracks and other surfaces that contribute to heat transfer, it both insulates and air seals, offering one of the easiest and most effective ways of weatherizing existing homes and new construction.
Among other benefits, it can help save on energy use, reduce heating and air conditioning equipment size, and reduce drafts and noise.
As a homeowner hiring someone to install SPF insulation for you, there are a number of important considerations, including specific questions that you will want to ask your contractor before, during and after the job is done.
