Spray Foam Insulation – Pros and Cons

Spray foam insulation in Minnesota creates an airtight seal and acts as a barrier for moisture and condensation in the nooks and crannies of your home. This improves temperature regulation, which translates into lower energy bills.

When sprayed on a surface, the tiny pockets (cells) of spray foam expand in place to fill all cracks and voids, making it an extremely efficient material. It also serves as a sound reducer, curbing outside noises and sounds between rooms.

Spray Foam Insulation Pros and Cons

Compared to fiberglass batt insulation, spray foam offers superior coverage. This is because a professional can simply point the spray gun in a tight space, squeeze the trigger, and watch the foam expand to fill the entire area. As a result, there’s no need to remove any existing insulation in the area that’s being insulated.

While there are some DIY options for a spray foam installation, many homeowners choose to hire a professional. Not only does this ensure a quality job, but it also gives homeowners peace of mind knowing that their spray foam insulation is working properly to protect and insulate their homes.

Before a crew arrives to install spray foam insulation, it’s essential that the area is clean and free of dust, dirt and debris. The installer will then prepare the area by scrubbing it down and vacuuming it to ensure it’s ready for insulation. When the spray polyurethane is applied, the “A” side of the product is combined with the “B” side, which contains polyols, catalysts, blowing agents, and flame retardants (although the exact formulas vary by manufacturer). When a reaction occurs, the spray foam insulation expands in place and forms an airtight seal.
