    Q:How much Installation would I need for a 14 x 40 building that’s 11.2 feet tall

    1 Answer
    Answer This Question

    A:  40' x 11.2' = 448 sq feet. (one long side of building) 14' x 11.2' = 156.8 sq feet (one short side of building) Two sides = 604.8 square feet [R-TECH 4' x 8' sheet = 32 sq feet] 604.8 / 32 = 18.9 sheets for 1 long side and 1 short side of building If all 4 sides combined = 37.8 sheets

      Love this product! Wish you still carried it. Larger sheets are just to large and unmanageable.
