What color is blown-in fiberglass insulation?
Blown fiberglass comes in three common colors: white, pink or yellow and the colors simply identify the manufacturer. Blown-in fiberglass insulation in attics typically has an R-value of 2.5 per inch. The density of the blown-in fiberglass determines the R-value just like it does for a batt.

Which is better blown in fiberglass or cellulose?
At 3.5 per inch of material, the R-value of blown-in cellulose is 23% better per inch than fiberglass batts! According to research done at the Oak Ridge National Lab, fiberglass loses up to 50% of its R-value in very cold conditions; making cellulose a better choice for homes in northern climates.
What are the disadvantages of cellulose?
Disadvantages. Installation costs for cellulose can be higher than for fiberglass. Cellulose insulation creates an enormous amount of dust when it is installed, so a certified breathing mask is absolutely essential. Dry-blown cellulose sags and settles, reducing its R-value over time.
What are the dangers of cellulose insulation?
If you use loose-fill cellulose insulation on the attic floor, the airflow from the vents will cause the material to drift, leaving spaces in the attic uninsulated. Also, as that outside air moves through the cellulose, pollen, bacteria, and mold spores can cling to it.
