The Advantages Of Foam Insulation

By Edited Jan 5, 2016 1 0

Foam insulation is the Cadillac of home insulation techniques and is becoming very popular, very fast. If you are considering getting foam insulation for your home or office, you've come to the right place. Here, we discuss the advantages of foam insulation. You will also learn facts about foam insulation to help you make the right decision when you are ready to buy insulation for your home.

Home insulation helps your home retain its heat in the cold weather months and helps keep your home cool during the warmer months. House insulation helps reduce heat loss in the winter which can help save money on energy bills.

Building insulation is measured by its resistance to heat, hence the R-value. The higher the R-value, the more resistant your insulation is to heat. Through the past century or so we have come to adopt building codes and those building codes have continued to evolve as time goes on. As the building codes have evolved, so have our methods of insulating. Foam insulation is quickly becoming the number one method of insulating a building.

There are several home insulation techniques that are used for insulating a house, the main insulation options being fiber glass insulation and foam insulation. Neither of these techniques are new, however with modern technology, foam insulation is increasing in popularity. Foam insulation used to be too expensive to be a practical energy saving option for the common home owner. Foam insulation has become less expensive in recent years and is an ideal method to insulate your new home or home remodeling project. In fact, there are now foam insulation kits that make the job even easier. If you want more information, read this article about foam insulation kits, you may find it helpful.

The Benefits Of Foam Insulation

In order to understand the benefits of foam insulation it is necessary to first understand what is needed in a home to help keep it dry, warm and cool. The R-value of insulation is directly related to how much room you have to insulate. In other words, if you have a home with 2X4 construction, you only have 3 5/8 inches of insulating room. If you have 2X6 construction you have over 5 inches of insulating room. Therefore, a home with 2X6 construction has the potential to get better insulation than a 2X4 home can. Aside from insulation, you also need a vapor barrier to help keep the moisture created by a drastic temperature change out of your home. This is traditionally achieved by tar covered kraft paper or by polyethlene plastic sheeting. Another factor is the air barrier. Typical fiber-glass insulation only slows air down and does not stop it.

Foam insulation can accomplish different things for your home at different coating depths. To simplify this concept, the advantages of foam insulation are as follows:

  • At one inch deep, foam acts as an air barrier, effectively sealing out any drafts. This helps to make your home air tight through the walls.
  • At two inches deep, foam acts as a vapor barrier and completely retards condensation and other moisture sources.
  • At three inches deep, foam acts as a vapor barrier, air barrier and gives you an R-value of R-19. R-19 is used to insulate 2X6 walls. This translates into being able to insulate a 2X4 home to the same R-value as a 2X6 home while providing a vapor and air barrier.
  • At five inches deep, foam gives you an R-38 value. This is sufficient for use in attics.
  • Foam is an excellent sound barrier.
  • Foam increases the rigidity of the home, effectively making your home stronger to withstand any structural damage caused by high winds or environmental risks.
  • Foam has no nutritional value. Who cares about nutritional value, you say? You do. Because foam has no nutritional value, mold cannot and will not grow on foam.
  • Unlike fiberglass, rodents cannot nest in or survive in foam insulation.
  • There are government tax credits available when you choose foam insulation for your home.


    • Initial cost. Foam insulation costs about $.80- $1.20 per square foot, per inch for coverage. However, the energy savings will pay for the price difference within a few years.
    • Temperature requirements. The surface of the walls or ceiling to be insulated need to be above 40 degrees Fahrenheit, in order for the foam to bond to the wall properly.

      Overall, foam insulation is a superior product that has been around for a very long time. It is now easily available to the average consumer thanks to the break through savings in production costs and the rising cost of traditional fiberglass insulation. Consider hiring an insulation company for foam insulation for your home. The money you save long term will be well worth your investment.

  • Despite all of these great foam insulation advantages, using foam to insulate your home does have a couple of drawbacks. The main drawbacks to foam include:
