Insulfoam taper is cut from the same high quality eps as our flat insulroof products and meets or exceeds the requirements of astm c578 standard specification for rigid cellular polystyrene thermal insulation. Tapered eps insulation provides the required positive slope to drain while retaining the structural and economic advantages of a flat roof deck. The goal of tapered roof insulation systems is to reduce or eliminate the amount of ponding standing water on the membrane when the roof deck does not provide adequate slope. After the decision has been made to use a tapered roof insulation system designers architects and specifiers must determine which tapered roof insulation system is best.
