HOMEOWNER GUIDES

R-Values & Performance

A depth measurement and an insulation R-value are related but different pieces of information. This topic covers thermal resistance, product instructions, coverage and the limits of judging performance from appearance. The launch guide explains the difference between an added amount and a finished target, and why one universal inches-to-R rule is not enough.
Use the materials guide to compare product forms and the attic insulation page to connect the specification to the work. Program targets belong to their specific rebate route; see the rebate guide for that separate question. For your own quote, ask which product and installation records will support the proposed level.
