The Coeur d'Alene Window Company is committed to providing industry leading thermal efficiency.  

Our window testing is certified through the NFRC (National Fenestration Rating Council.

The NFRC assigns ratings for several thermal factors including U-value (the reciprocal of an R-value), solar heat gain and air leakage.  

The NFRC also rates a window for visible light transmission and condensation resistance.

To see complete test results for all products, please click on the NFRC logo to be routed to their official testing area.

We have included testing for several configurations here as well.  TESTING DATA MAY NOT BE CURRENT AS OF THIS DATE AND MAY TAKE SOME TIME TO BE UPLOADED TO THE NFRC SITE.  Please contact a Coeur d'Alene representative for the most up to date information.



Rebates are often available through local utilities or state programs when you upgrade your windows with newer more energy efficient models.

Make sure you confirm the availability of rebates, low interest loans or other incentives directly with the issuing body.  The Coeur d'Alene Window Company provides these links as a service only and makes no promises or guarantees that the information is accurate or current as of this date.
