What is blanket insulation?

Do you need to insulate your home in Southern California? Chances are you’ll probably use a blanket insulation system. Consisting of either batts or rolls, blanket insulation is one of the most commonly used types of insulation.

This type of insulation is made up of small fibers—mostly fiberglass but also sometimes mineral wool (rock and slag) or natural fibers. Roll insulation comes with and without facing, and continuous rolls can be cut and trimmed to fit the space you need to fill. Batt insulation is available in various widths and pre-cut panels.

Where to Install Blanket Insulation

Blanket insulation is typically installed in unfinished walls (including foundation walls), floors and ceilings. It is fitted between joists, studs and beams that are free from obstructions like pipes, wiring, ducts, etc.

Blanket insulation can also be used as acoustical insulation for retrofitting warehouses and other such commercial buildings, as well as thermal insulation for areas inside the home (often in attic spaces). In fact fiberglass insulation is one of the best types of insulation to use for sound control!

The R-Value of Fiberglass Blanket Insulation

The R-value of fiberglass blanket insulation depends on its thickness. It has an R–value of approximately R-2.9 to R-3.8 per inch of thickness. To give you a better idea, insulation that is 3 ½ inches thick has an R-value of about 11, and insulation that is 12 inches thick has an R-value of about 38. R-value can be tricky to understand—but a professional insulation company will be able to help you out!
