Tapered Polyiso Insulation: Commercial Roof Systems – ISO301

The goal of tapered roof insulation systems is to reduce or eliminate the amount of ponding or standing water on the finished membrane when the roof deck does not provide adequate slope. Draining the water in a timely and efficient manner minimizes the adverse effects on roof membranes. A properly designed tapered roof insulation system not only provides the positive drainage needed, it also helps extend the life of the roof membrane and provides thermal value, reducing the heating and cooling expenses of the building owner.

Learning Objectives:
  1. Understand the features and benefits of tapered polyisocyanurate insulation.
  2. Identify and understand key terms in a tapered insulation system: panel, profile, and slope.
  3. Identify specific design questions to consider when comparing tapered quotes: minimum R-value, slope, squares of fill, 2-way or 4-way design.
  4. Accurately compare different tapered designs and quotes.
