Set of 3 Sheets of Continuous Strand Fiberglass! The sheets measure 50 inches wide, and .06 inches thick. The weight is 2 oz per square foot. Please note, we are by NO MEANS fiberglass experts, these specs are our best effort of discerning the way fiberglass is measured. These are pre-cut, so we cannot give you bigger sheets. You will not receive one continuous 3-yard piece of fiberglass, these are pre-cut, so you will receive between 2-4 pieces that equal out to 3 Yards.
