Here is why fiberglass does not make a good insulator

There are many reason that fiberglass does not make a good insulator. Here is a short list:

* Fiberglass insulation loses 40% of its insulative properties when outside temperatures drop to 20 degrees. Not good news for New Englanders.
* A 1.5% increase in moisture content inside a wall or ceiling cavity reduces the R-value of fiberglass insulation by up to 50%.
* For fiberglass insulation to be effective it must touch stud cavities on all six sides, with no air gaps.
* Fiberglass insulation must be fully expanded. Stuffing insulation into gaps eliminates its insulative properties.
* In shell wall cavities, areas surrounding utility outlets are impossible to properly insulate using fiberglass.

Soy-based spray foam insulation is the way to go. Learn more about our spray foam products on our website http://www.greenbearinnovations.com.
