Spray foam insulation is sold in cans for small jobs. You can purchase it from home improvement centers, hardware stores, and even some department stores. For bigger jobs, large quantities of spray foam can be pressure-sprayed into place by professionals. The traditional applications of expanding polyurethane foam are to plug up drafty doors and windows, insulate new and old walls, and seal and insulate floors. But that's not all spray foam is good for. There are several unusual and very useful ways to use spray foam insulation. Continue reading to learn more:
Seal Duct Work
In order for your HVAC system to run efficiently, all the ductwork in your home must be sealed tightly. Use foam insulation to plug up any holes and cracks to prevent air from escaping. This will improve the comfort level in your home because your HVAC system will be able to properly control the temperature. You will also notice a reduction in your energy bill because the system won't have to work so hard to maintain the desired temperature in your house.
Protect Fragile Items When Moving Or Shipping
One of the most frustrating things about moving is packing fragile items so that they won't break, and then worrying about those items throughout the whole move. Spray foam is perfect for this task. Simply spray foam into a sealable plastic bag until it's about half or three quarters full, and then close it up. Put the bag at the bottom of a box and put the first layer of breakables on top. Then put another foam-filled bag on top and gently press down. The foam will mold around the fragile items to create a perfectly shaped shock-absorber that will protect these delicate items during transit.
Provide Pest Control
Spray foam provides many different types of pest control solutions to keep bugs and other small creatures out of your home. Some of these solutions include:
Apply foam insulation between the garage door jam and the wall to stop bugs and rodents from getting in.
Spray a wasp nest with pesticide and then plug the hole with spray foam to seal it.
Keep squirrels out of your attic by putting chicken wire in the spaces underneath the eaves of your roof. Then spray foam insulation on the wire to create an incisor-proof barrier.
You can plug up other small holes in your exterior walls, like those left behind from old cable or satellite TV cables, to prevent little pests from entering your home.
Improve Insulating Properties In A Cheap Cooler
The main characteristic that separates a cheap cooler from an expensive one is the amount of insulation it has. Go ahead and buy an inexpensive cooler. Then take it home and drill two small holes into the hollow cover. Insert the straw end of the spray foam can into the hole and to fill the hollow cover with insulation. The other hole is there to allow for expansion so the foam won't crack the cover. Once hardened, scrape off the foam that has overflowed through the holes to make the cooler more aesthetically pleasing. Or, leave it there for a fun conversation starter.
Here are a few more unusual ways to use up your can of spray foam:
Quiet your washing machine by spraying some foam insulation where the water supply pipes meet the walls.
Stop plastic waste lines from your toilet from rattling every time water runs through them by spraying foam insulation around the pipes where they meet the floor joists.
Use this foam to bond rocks together when building a waterfall in your backyard.
Spray foam insulation around the foundation of replacement windows to anchor them to masonry walls.
Fix a loose pull knob on a hollow bi-fold door by injecting spray foam through the screw hole. This gives the pull something to anchor too.
Since a lot of foam comes in a can of foam insulation, knowing some of these alternative uses is a great way to get your money's worth. You may even find that spray foam insulation is the better choice over other products specifically designed for a particular task. Consider keeping a can of foam insulation around as your go-to solution to many different household issues.
