EFFECTIVE R CALCULATOR

 

 

 

*The Effective R Calculator tool is fully optimized for best performance in
Google Chrome.

The purpose of this R Value 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.
