Effective R-value calculator with durability analysis
*The tool is fully optimized for best performance in Google Chrome.
The purpose of this online tool is to provide designers with climate zone-appropriate insulated wall assembly solutions that are easily comparable with national and provincial energy efficiency prescriptive provisions.
Each assembly lists:
- Effective thermal resistance Reff* for complying with the National Building Code (NBC) for houses and the National Energy Code for Buildings (NECB) for larger buildings
- Installed R-value for complying with the Ontario Building Code
- Centre of cavity R-value for complying with the Quebec Construction Code.
*The calculation of effective thermal resistance is performed in compliance with NBC Subsection 9.36.5. of Division B.
Each assembly comes with a climate-specific colour-coded durability assessment, which has been determined considering computer analysis and field experience by building science experts in Canada.
