Foam Insulation: A Boon To Buildings

Spray foam insulation is made of polyurethane foam, which is the same insulation that manufacturers have used in refrigerators and hot water heaters. This liquid is pumped through spray nozzles. First you conduct a test spray and you must remember to use it sparingly because it will expand to over 100 times its size. You should spray between the gaps and on the exterior and allow it to expand so it fills the gaps. When it lands around your attic or side walls, it expands to form insulation. Then take a handsaw blade and cut away any excess foam that protrudes out. Then you are ready to install the drywall.

Foam insulation protects the environment by minimizing the use of harmful chemicals. Traditional insulating materials are usually made from fiberglass or cellulose that insulate the house but can create a lot of waste and may also damage the environment. Many foam industries have decided to create a quality product with the highest renewable resource content to encourage homeowners to purchase this product as it protects the environment. Earlier individuals used traditional insulating materials like fiberglass and cellulose. Now, with the invention of spray foam, the product can seal and fill tiny cracks and crevices that may not be even seen with the naked eye.

Spray Foam insulation has a high R-value when it comes to thickness. Thanks to its high R-value, homeowners can use different construction, that can save framing costs and illuminate door jambs. This foam can also increase the living space by as much as an extra closet all around the house. The foam insulation can help control moisture and condensation and it tends to not shrink or settle. It is a fire and insect resistant too.

Most individuals hire a contractor who is certified in applying spray foam insulation for the whole house. If you are insulating a small wall or a portion of the house, you can probably buy a tank of spray foam from a contractor but if you plan on undergoing a large project you should hire a professional to make sure the job is done correctly.

Since it is not a do-it-yourself project, you may have to endure a cost by hiring a contractor. The contractor will have the machinery available to do the job quickly and efficiently. The process could be messy, that makes it is easier for new construction rather than existing homes. Even though it is easier to do on new construction, thousands of people are getting spray foam insulation on renovations. Using this product in sidewalls may be difficult and delay the process especially if electrical and plumbing contractors do not regularly work with the material. The installation cost of the versatile spray foam can be as much as three times more than traditional materials. However, the increase in R-value and air sealing can lower your utility bills by as much as 30 percent, which means you will pay back the difference in energy savings in less than five years.

If you are renovating your house or constructing a new house, you should consider spray foam insulation. Even though the installation costs can be high, the benefits outweigh the costs.
