It’s still October, but if you’re like most of us, your thoughts have already started to wander to the upcoming holidays and inevitable colder weather. It will be here before you know it! When it gets cold outside, we normally rely on our HVAC systems to keep our homes warm and comfortable. But if your house is not properly insulated, your HVAC system will have to work harder than normal and your home still won’t be as comfortable as it could be.
That’s where spray foam insulation comes in.
Spray foam is exactly what it sounds like — a liquid foam that hardens to form a solid, air-tight foam insulation. It is an environmentally-safe, non-toxic way of insulating residential and commercial buildings. As opposed to traditional insulation, it is installed by directly spraying the polyurethane foam onto the wall and floor cavities. It can also seal spaces around electrical outlets and light fixtures.
Traditional insulation, like fiberglass and cellulose, operates like a wool sweater. It can keep you warm, but air is still able to pass through. This air leakage is what causes high heating and cooling bills in your home. According to the US Department of Energy, 40% of a home’s energy is lost as a result of air infiltration through walls, windows and doorways. Spray foam insulation, on the other hand, acts as a hard, air-tight seal against your walls that prevents cold air from seeping into your home during the winter months. It can insulate as much as 50% better than traditional insulation products.
While traditional insulation is cheaper than spray foam insulation, it is also less effective – especially during the cold winter months. Spending a little more to invest in spray foam insulation will pay off in the short- and long-term.
There are two types of spray foam insulation – closed cell and open cell. Open cell spray foam is softer and weaker form, because of the tiny open cells within the foam. Closed cell spray foam, on the other hand, creates a harder foam because the cells are closed and packed tightly together.
Each type has its own advantages and disadvantages. Open cell uses fewer chemicals, provides a strong air barrier and can reduce outdoor sounds; however, it is not as air-tight as a closed cell foam would be. Closed cell is much denser, making it a stronger barrier against air leakage and water vapor. It can be used anywhere in the home as well as outdoors. Because of its stronger structure, though, it is more expensive than other alternatives.
