Times are hard and seem to only be getting harder. One of the newest products available right now is Spray Foam. Spray foam is highly energy efficient. Although a little costly out of pocket spray foam quickly pays for itself.
The company I have become fond of is Natural Polymers. The main reason I have chosen this company is because they are GREEN. They offer green materials, so while you are making your home more energy efficient you are also using recycled materials, which is very cool. Their product is Low Emitting (1-4 points) and recycled materials (1-2 points)
Getting your home blown with spray foam while under new construction is ideal because the foam covers every nook and cranny, leaving no room for air or bugs to make its way through and significantly lowering your energy bills. Spray foam is not just for new construction only. You can call a local Spray Foam Contractor and have spray foam installed in attics, under pier and beam (which is really helpful with noise, weather, critters making nest and so forth) and even covering the roofs of trailers. Trailer homes are really benefited by spray foam as they tend to use a lot of energy escaping from the roof. There are very few things you can do to help out your trailers energy bills, spray foam is one of them.
When looking at the various ways you can make your home more energy efficient, do not over look spray foam, it is an inexpensive way to cut back on energy bills.
