Spray Foam FAQ’s

The answer to this question is very difficult to explain. Technically spray foam is rated by an R-Value per inch. The R-Value really does not apply to foam because foam does not only insulate, but also reduces airflow, which is the root cause to energy loss. Please read the following article for more info on R-Values. R-Value Article and “R” Fairy Tale The Myth of Insulation Values by David South

The Department of Energy has concluded that 40% of energy lost in a home is due to unwanted air infiltration. Spray foam insulation is effective in sealing these air infiltrations and providing an effective air barrier. With the installation of Spray Foam Insulation an homeowner can expect an energy savings of 30-70% dependent upon the time of year.

A conservative estimate would be 3-5 years for a return on your investment. It would depend a lot on your life style and whether or not the utility companies raise their rates (they wouldn’t dare)

OK lets do some math. You are getting a new home built. Your new home is 1800 sq ft .and will cost $175,000 with fiberglass insulation. Using open cell foam the price is $178,000. On a 30 year mortgage at 6% your fiberglass house payment is $1050 per month your foam house payment is $1067 per month. $17 difference. Now forgetting all the other benefits of foam insulation if you can reduce your energy bill by up to 50% you will save more than the $17 dollars a month.

Open cell foam is also referrred to as 1/2 lb foam. Open cell foam is a great product and offers insulation value far superior to batt or insulation. It is effective in providing an effective air barrier, sound deadener and is somewhat hydrophobic. Closed cell foam also referred to as 2lb foam is more dense than open cell foam and is an effective moisture barrier as well as an effective sound and air barrier.

Choosing between open cell and closed cell foam will depend on the specifics of your home and your budget. Closed cell foam has a greater R-Value per inch than open cell foam, but costs more.

The most important thing to remember is Spray Foam Insulation is a far superior way to insulate your home and offers immediate money and energy savings for your existing or New Construction home.

Why Should I use Foam Insulation?

Should I Use Open Cell or Closed Cell Foam?

What is the energy savings I hope to get from Spray Foam insulation? How soon will I get a return on my investment?

What is R-Value and does it apply to foam?

New Homes– All electrical and plumbing should be complete. Spray Foam insulation should be the last trade before drywall is installed.

Existing Homes– Typical installation is in attic spaces and crawlspaces. All items stored in attics and HVAC units should be covered with plastic or removed. All fresh air vents should be installed for gas furnaces and hot water heaters in the attic.

What should I do to prepare for the installation of Foam Insulation?

Foam Insulation is the most energy efficient and effective means to insulating Attics, Walls, and Crawlspaces. It provides a completely sealed envelope which virtually eliminates air infiltration to the home which is the leading cause of energy loss. It’s application has a energy saving benefit that is evident in new homes or existing homes.
