Products / MIGHTYPLY Roofing Membrane

MIGHTYPLY Roofing Membrane (product code 2890) is a black polyester-reinforced ply coated on both sides with asphalt, used with MIGHTYPLATE or MIGHTYPLATE II roof coatings as reinforcement in cold-process built-up roofs, for cap sheeting over existing roofs and for new construction. The data sheet lists a 50 mil thickness, a weight of 0.33 pounds per square foot, and a 1 by 20 meter (215.2 square foot) roll covering 190 square feet in one ply. New construction requires a double-ply cap sheet, and the maker lists aluminum roof coating or ceramic roofing granules as optional surfacings. The sheet mentions a limited warranty without stating a term.
