Full answer is here. Considering this, what is the density of fiberglass insulation?
Loose-Fill and Blown-In Insulation
| Cellulose | Fiberglass | |
|---|---|---|
| Density in lb/ft3 (kg/m3) | 1.5–2.0 (24–36) | 0.5–1.0 (10–14) |
| Weight at R-38 in lb/ft2 (kg/m2) | 1.25–2.0 (6–10) | 0.5–1.2 (3–6) |
how long is a roll of fiberglass insulation? Owens Corning R-19 Kraft Faced Fiberglass Insulation Roll 23 in. x 39.2 ft.
Also Know, how much does a roll of insulation cover?
The cost for batt and roll insulation starts at $0.12 to $0.16 per square foot for a three-and-a-half-inch barrier that provides a value of R-11. The cost of a single roll of reflective insulation varies according to its R-value.
How thick is r19 fiberglass?
An example would be compressing R-19 insulation (typically 6 ¼”) thick into a 2x4 stud cavity that is 3 ½” deep. A. When you compress fiber glass batt insulation, the R-value per inch goes up, but the overall R-value goes down because you have less inches or thickness of insulation.
