What is Window Insulation Foam? (Types/Manufacturers/Cost)
There’s a fix to the outside air leaking in around your windows – foam insulation.
Now you’re probably wondering what window insulation foam is and how it works. All will be revealed in good time friends – or as you read this article.
Window insulation foam can help reduce those drafts you get around your windows. In some cases, when the windows are installed, the cavity around them isn’t filled with any kind of insulation. Those leaky areas can contribute to your home being uncomfortable, as well as high energy bills.
We here at RetroFoam of Michigan are on a mission to give homeowners all the information they need to make an informed decision. We have insulated more than 10,000 projects with spray foam and injection foam, so we understand how the material works and how it can help create an air barrier in your home.
Now let’s take a look at what window insulation foam is, who makes it, and how much it costs.
What is Window Insulation Foam?
Window insulation foam is a low-expanding, low-pressure polyurethane spray foam that is designed to create a weather-tight seal around windows, as well as around doors.
Not to be confused with froth packs, window insulation foam is sold in a can.
Installing Window Insulation Foam
There are two ways you can install window foam insulation – removing the window frame or removing the window itself.
The best method to ensure you fill the cavity around the window is to remove the frame around the window and then spray the canned foam in the gap. The foam, if installed properly, will create an air seal around the window so you don’t experience any more leaks.
Because window and door insulation is a low-pressure foam, the material doesn’t have a high expansion rate and is easy to control during the install. The biggest thing to remember is ensuring you fill the space around the window completely.
To install window insulation foam in your home, you will need at least three or four cans.
