Columbia has the widest range of ENERGY STAR® certified skylights in Canada.

ENERGY STAR® is a joint environmental program of the U.S. Environmental Protection Agency, the U.S. Department of Energy, and the Canadian National Resource Council that helps consumers identify the most energy-efficient products on the market.

Energy efficient choices can save families about a third on their energy bill with similar savings of greenhouse gas emissions, without sacrificing features, style or comfort.

  • The current iteration of the ENERGY STAR® Canada standards and targets (Version 5) took effect on January 1st, 2020. The most significant difference between version 4 and 5 is the elimination of all zones across Canada.
  • In version 5, all skylights are required to have a maximum U-factor value of 2.29 (metric) or 0.40 (imperial) to be ENERGY STAR® certified.
  • By choosing an ENERGY STAR® skylight you save on energy costs and protect the environment.
  • Columbia is the only skylight manufacturer offering triple glazed on all skylight models, fixed & venting, standard and custom sizes.
  • Every glass skylight model Columbia manufactures has an ENERGY STAR® glazing option.
