Spray Foam Insulation: How It Works
If you own a home or business, you’ve probably spent at least some time
thinking about various forms of insulation. Spray foam insulation is one
such form and it works a little differently than the traditional pink
fiberglass stuff. Here is how it works.
The primary trait of spray foam insulation that sets it apart from other forms is its ability to expand. When mixed with oxygen as it is when sprayed, it can expand beyond its original dimensions. This property allows it to be sprayed in hard to reach places, but it also means installers have to be cautious about where they put it. More than one homeowner has had structural damage due to improperly placed applications. The insulation has the potential to expand to almost ten times its original size when it gets wet, which can easily cause damage to wood and other materials.
Why is this such a good thing? Unlike traditional fiberglass sheets, the spray foam insulation creates a seal. Through this seal, no air will escape or enter. That means a tight barrier, which is the best kind of insulation a homeowner can hope for. If you’re serious about keeping your electricity bills down, it is the only way to go. When the house is properly closed off, the air conditioner and heater doesn’t have to work nearly as hard to achieve the same results. As an added bonus, it will protect the house from rodents and insects that might want to make their home in the attic.
If you’re interested in spray foam insulation, you should contact some contractors near you to see what they have to say about setting it up in your house. If you have the choice, call around to a couple of different companies and see what kinds of prices they offer. Don’t make your decision solely on price, though. Find a contractor who is well known and respected in the community and has the references to let you know that
