If you plan to install spray form insulation, you can easily get confused by the various available. You should know that not all spray foam is created equal, and many different technologies are at play. Here’s a guide to the four primary types of spray foam insulation to help you determine what’s right for you.
Firstly, there is the Gap And Crack Filler.
As its name suggests, this spray foam insulation can also be used to fill 4 to 5 inch gaps and cracks as it expands after spraying. There is also the Big Gap Filler spray foam insulation which works best to fill really big gaps as it expands much more than the Gap and Crack Filler.
Another type of spray foam insulation is Window and Foam, which is specially designed for use on doors and windows between the jam and frame. Unlike other types of spray foam insulation, Window and Foam doesn’t expand in a manner that pushes against door and window frames. There is also Pest Block spray foam insulation which contains components repulsive to rats and other pests. If you live in an area with a high population of rodents, Pest Block spray foam insulation could be the best for you.
