Three Alternative Uses For Spray Foam Insulation

Posted on: 2 December 2014


Spray foam insulation, which consumers can purchase in smaller amounts via spray cans, has some advantages over traditional rolled insulation and blown cellulose insulation. What you may not know is that you can use spray foam insulation in some other, off-label ways. If you have never tried to use spray foam insulation for anything other than insulating your home, you may want to give these three alternative uses for excess insulation a chance.

Sealing an Air Leak in Tires

You cannot use the spray foam for leaks that you have on the tread surface as it will just crunch and flake off, but you can use it if someone stabs your tires with something sharp. If you are lucky and the hole is smaller than a couple of inches, and the tire is not completely flat, take some spray foam insulation and use it as a patch on the hole. Wait until the spray foam has solidified and dried before driving. Then the tire will not lose any more air, and you can drive your car to the nearest air pump and refill the soggy, patched tire.

Sealing Cracks in Your Foundation

You may not want to do this for a long-term solution, since you will have to repair your foundation before the cracks make it much worse than it presently is. Yet, for a short-term solution, using spray foam insulation to seal cracks in your foundation will help you keep bugs, rodents, and rain from entering your home. Your foundation repair contractor will have no trouble removing your temporary patch of foam insulation when he or she arrives to fix your foundation. A good painter's knife and some elbow grease will scrape it off and out.

Patching a Hole in Your Watercraft

Surprisingly, spray foam insulation is an excellent boat, canoe or kayak patch. Because it is designed to be waterproof and keep precipitation out of your attic, it doubles beautifully as a watercraft patch. Once your boat is back on land, you can remove the patch and have a boat repair service fix the hole.

Paying and Using What You Pay for

Since your roofing and insulation contractor charges you for "x" amount of spray foam insulation, whatever he or she does not use technically belongs to you. The application process for commercial spray foam insulation is different from the cans you buy in a hardware store. If you ask your contractor to give you the remainder of the product you paid for, you will have to find your own means of dispersing it for these alternative uses. 

It might be a good idea to talk to an insulation provider like Specialty Insulation about how safe it is to use the specific type of spray foam insulation you have for these other uses, before giving them a try.
