How many roles needed for 1050 SHARE FT 25X42
Asked by: Johnny
The square footage of each roll is (15"*470")/144 = 2500 sqft/roll. You have 1050 sqft of space to cover. 2500/1050 = ~3 rolls.

Bought 9 rolls, 4 of them are gorgeous snow white, the other 5 are black?? Is that normal? Or did they get wet & moldy?

Asked by: Blou
Hello Blou, Thank you for your interest in Johns Manville's fiberglass building insulation. Johns Manville manufactures fiberglass batts that are either white or brown in color. There is a binder or glue that holds the fibers together which is either white (acrylic) or brown (bio based). Although the products have a different appearance, they both perform the same at a given thickness and density. Best regards, Doug Fast

Wish i knew that they had different widths though. I should've used the 23" instead of the 15". My own mistake. I simply doubled up. Good for them bad for my wallet.
