Benefits of Spray Foam Insulation
Spray foam has many benefits over other types of insulation. One immense benefit of spray foam is its R-Value. Another tremendous benefit that spray foam gives homeowners is that it keeps mice and other pests away.
What is R-Value?
R-Value is a measure of resistance to heat flow through a given thickness of a material, like insulation, with higher numbers indicating better insulating properties. With an R-Value of about 7 per inch, spray foam allows a higher R-Value to be installed in less space. For example, you could use 2 x 4 walls instead of 2 x 6 in specific applications.
You can also get more out of spray foam because it stops airflow on top of its insulating value. When sprayed on, the foam will expand to fill any gaps or cracks there might be. This virtually eliminates any drafts you might have in your home.
Once sprayed, spray foam is also a vapor barrier. You could save money in situations where one is needed. Another benefit you can get from choosing spray foam is to spray it on many different surfaces. From your attic to your foundation, it can be used almost anywhere.
Homes and commercial buildings insulated with spray foam have better protection against things like mildew and mold. The polymer within the insulation is inert, meaning that it provides no food source for mold or bacteria. It also provides a moisture barrier preventing mold from growing.
Since walls are a building’s primary structural component, they need to be sturdy. When spray foam insulation is inside of walls, it provides additional strength. The building is supported more efficiently.
Can spray foam be used in
existing walls with no insulation?
Closed-cell spray foam insulation, which has the highest R-Value, needs to be sprayed onto the flat surface. If your walls are closed in from both sides, that will not work. However, we have other great options for you.
Our best option for insulating walls that are entirely closed is injection foam. Injection foam is an open-cell type of spray foam. It is designed to rise slowly, allowing it to travel down to the bottom of the wall cavity and slowly rise to fill all nooks and crannies.
Injection foam is usually installed by removing pieces of your siding, drilling holes through your wall, plaster, or sheetrock. Then, we fill the wall cavities with foam. Once the walls are filled with foam, we return your siding to its original condition. Some injection foam applications may vary.
