The Truth About R-Values

The Truth About R-Values

You are here

R-value does not measure heat movement carried in the air.

When the time comes to assess the type of insulation your home needs, R-Value is a common term you will hear. Insulation R-Value measures how well a particular insulation resists heat flow. It does not measure heat movement carried in the air.

It’s important to note that installing thicker insulation, or insulation that has a high R-Value doesn’t necessarily mean that your home will then have a better insulation and air seal. Traditional types of insulation offer R-Value that relates only to insulating power, so you may actually continue to have higher-than-average heating and cooling bills. That’s why you should be thinking about an insulation and air seal material, like ICYNENE spray on foam, when choosing your insulation.

Air Loss Facts

  • Air leakage can be the underlying cause of up to half of your home’s energy loss.
  • When your home isn’t properly sealed, the gaps found throughout your home’s building envelope can add up to the size of a basketball.
  • All of those gaps can end up leaking enough air to fill two blimps every day.

Selecting an insulation and air seal material

Icynene sprayed in foam is an insulation and air seal system that works to help ensure that your home doesn’t suffer from air loss, while providing an effective R-Value. By expanding 100 times its original size, ICYNENE seals cracks and gaps in attics, walls, ceilings and other spaces, where air might escape. It does this better than traditional types of insulation.

* R means resistance to heat flow. The higher the R-value, the greater the insulating power. Compare insulation R-values before you buy. There are other factors to consider. The amount of insulation you need depends mainly on the climate you live in. Also, your fuel savings from insulation will depend upon the climate, the type and size of your house, the amount of insulation already in your house, and your fuel use patterns and family size. If you buy too much insulation, it will cost you more than what you'll save on fuel. To get the marked R-value, it is essential that this insulation be installed properly.This can help to reduce your heating and cooling bills. Icynene sprayed in foam insulation is able to provide a high, code-compliant R-Value, while also air sealing your home. You’ll be maximizing your comfort while minimizing your heating and cooling bills.
