How Much Coverage Does One Can of Spray Foam Provide?

Are you looking for a quick and easy way to seal gaps in your home and save on energy costs? Aerosol foam insulation is the answer. Seal spray foam is a great option as it can be applied directly by connecting a spray nozzle to the can. There are different versions available, with some expanding more than others. The minimum expansion type is suitable for applications where things can move, such as window frames or doors.

When it comes to coverage, one board foot equals one square foot of coverage at one inch. To provide adequate air sealing, a minimum of two to three inches of spray foam is required. Consider the size of the area to be insulated and the proper thickness in inches of foam needed. For small projects, a smaller two-component spray foam kit may be sufficient.

I have used Seal Spray Foam to fill in any space between the rough edges of the sheets and walls when insulating my workshop. It allows several users to spray at the same time, instead of just one with larger two-component tanks. A 27.4 ounce can, pack of 24 with gun, nozzle and cleaner yields 600 board feet. Keep in mind that conditions of use will have a big effect on the usable amount of foam.

You'll also need to make sure you buy plastic and adhesive tape to prepare it, to make sure that the spray foam doesn't get where you don't want it to.
