What if I find a fenestration product with an ENERGY STAR label that does not show information for the Canadian climate zones?
• This may be a product that qualifies for ENERGY STAR in the United States but not necessarily in Canada. Remember, specific ENERGY STAR criteria have been developed for Canada’s climate, which tends to be colder in winter than most parts of the U.S. A fenestration product that does not show the Canadian climate zones may not qualify for ENERGY STAR where you live.
