What is a Spray Foam Insulation Retrofit?

spray foam insulation toronto Like most other insulation varieties, spray foam insulation is usually installed in homes during the construction process. This is because insulation can easily be installed inside wall cavities before drywall is installed over top of it. A complete home retrofit is when spray foam insulation is installed into an existing building. This is often facilitated by “injecting” the insulation into small openings in wall cavities. This will allow the insulation to be installed without compromising the structure of your home or building.

Initial Consultation and Home Assessment

Since insulation retrofits require your insulation installation company to work around the existing structure of your home, you will need to conduct both a consultation and a home assessment. The consultation with the installation team will be used to establish your goals. For some homeowners, their goal is to decrease utility costs, whereas for others, comfort is their priority. The installation team can proceed accordingly.

The home assessment will allow the insulation team to asses your exisitng insulation and areas that may be more or less insulated, identifying priority areas like attics, crawl spaces or basements.

Installation Process

The actual installation process of spray foam insulation is rather seamless and is something that most homeowners do not need to be present for. Your insulation team will seal any significant air leaks, install the spray foam insulation with their expert techniques, and then ensure that your home has enough time to cure and off-gas. Once the off-gassing period is over, homeowners can go back home and enjoy the benefits of their new insulation.

Benefits You’ll Notice After Your Spray Foam Insulation Retrofit

Improved Energy Efficiency: Spray foam insulation has a high R-value, which will result in lower heating and cooling costs.
Stable Temperatures: Spray foam insulation can help promote temperature stability, allowing for more comfortable indoor temperatures.
Fewer Drafts: Fresh insulation helps create a barrier between the inside and outside of your home, preventing unwanted air and drafts from entering.
