The simple lack of adequate insulation is rarely a problem in new homes these days. However, insulation improperly installed, can effectively “kill” or significantly lower anticipated R-values.

Take for example a ceiling with an R-30 insulation batt that has been significantly compressed. The effective R-value could be reduced in half to R-15. Likewise, wall insulation that contains voids or gaps and is not properly aligned or in contact with the sheetrock wall can suffer the same fate.

Proper installation techniques result in insulated wall and ceiling assemblies that function as designed. The benefits for the homeowner translate into a more energy efficient and comfortable living environment.

There are two basic guidelines builders should consider when installing insulation.

First, insulation should always be installed according to the manufactures’ recommendations, which includes attention paid to gaps, voids, compression and wind intrusion. And secondly, insulation and the air barrier must be installed in physical contact with each other.

After insulation has been installed, an inspection should be performed to determine if proper installation techniques were followed. Insulation contractors who are held to high standard of quality will perform to that level if they know there work will be scrutinized.
