R Value Calculator

How does your wall actually perform?

Enter your wall configuration below and see how your Total Wall R-Value compares with and without a thermal break. The calculator accounts for frame material, insulation, cladding and stud layout to give you a clearer picture of where performance is being lost and how much you can gain.

*Please note, results are indicative and based on standard wall configurations. For project-specific energy modelling, we recommend working with a qualified energy assessor.
