Houses that are in a cold or hot climate can benefit a lot by getting the spray foam applied in their attic. Spray foam is known to seal any small cracks in the attic, completely insulating it and saving you lots of energy.
However, a poor spray foam insulation job can badly hurt your energy savings, and might even damage your roof. So, if your are a homeowner looking to get spray foam applied in your house, here are some mistakes that you should avoid. If you have a contractor, keep a close eye on their work and see if they are repeating any of these mistakes.
Using The Wrong Type of Spray Foam
There are two types of spray foam that is sold for insulation. Open cell and closed cell. Open cell spray foam, as the name suggests, us made up of open cells. These cells let the outside come in the foam, and so, this foam can catch moisture over time.
Closed cell foam on the other hand is very different. It is made up of closed cells that do not let any air come into the foam. This way, the foam does not allow the moisture to seep in.
Open cell foam is not fit for use in hit climates. In these climates, humid cold air can come inside the foam and make a condensate to damage the roof of your house. Closed cell foam is your best bet if you live in a cold area. Closed cell foam can also be used, but you will have to install vapor barrier alongside this foam.
Uneven Spraying of Foam
Another thing that can ruin your spray team’s effectiveness is uneven application by the contractor. So, you should only hire qualified spray foam insulation contractors to do the job for your house.
