What is R-Value?

The R-value is a measure of the insulation batt's resistance to heat flow, also known as thermal resistance. The greater the R-value, the greater the resistance to heat transfer, and the greater the insulating effect and subsequent energy savings.

When it comes to choosing the right insulation for your home, select the required R-value at a thickness that fits into the available space.

A holistic approach to insulation

In order to get the most benefit from insulation it is important that a holistic approach is taken to address heat gain through windows, skylights and other penetrations. Shutters, deciduous trees and internal fixtures such as blinds or curtains can be used to reduce heat gain and loss, in combination with appropriate and thorough insulation.
