The purpose of roof insulation is to ensure that air does not escape from your home through the roof. It acts as a secondary barrier to other insulation installed in your home. An “R-value” distinguishes all roof insulation. The “R” stands for “resistance” and refers to the resistance a material has to heat flow, or temperature conveyance. The higher the number, the better the insulation.
The photograph shows a form of roof insulation that we use for all of our single-ply and metal roof installation projects. R-Tech is a brand of fanfold roof insulation, which is a lightweight yet high-performance sheathing that consists of a superior closed cell, creating excellent resistance to water.
This type of insulation lays on top of the sheathing and acts as an underlayment for the single-ply membrane or metal panels.
