Rolled insulation is another type of insulation blanket similar to batt insulation. The main difference between insulation batts and rolls is that batts are installed in pieces, while rolls are rolled out between wall and ceiling framing. Insulation rolls leave less opportunity for gaps between sections, making them sometimes more effective than batts.
Best for unfinished walls, floors, ceilings and wherever long and continuous insulation pieces are needed.
Available in pre-cut widths to fit between studs and joists.
Come in continuous lengths ranging from 20- to 40-feet.
Another one of the most affordable types of insulation. Comparable in price to batts.
Like batts, standard fiberglass rolls have R-values ranging from R-2.9 to R-3.8 for every inch of thickness. High-density insulation rolls can have R-values as high as R-4.3 per inch.
