Blanket Insulation

Do you need insulation for your home or commercial building? Chances are the project will require blanket insulation, which can be made up of rolls or batts.

Blanket insulation is one of the most commonly installed types of insulation and is often made of fiberglass batts. It is mainly installed in spaces that are relatively free from obstructions.

Blanket Insulation Installation & R-Value

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 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. A professional insulation company will be able to answer all your R-value questions.
