Tapered Insulation Systems

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. Tapered polyiso is frequently the tapered system of choice.
