What is an ENERGY STAR® window?
ENERGY STAR® means a window (or a specific config) meets efficiency criteria for the Canadian market. It is not a window “style”: it is measured performance.
Why it matters here
Better everyday airtightness and insulation, more stable comfort, and often a requirement tied to grants like Rénoclimat — under program conditions.
Watch the options
A grille, an out-of-range size or certain glazing can take a config out of ENERGY STAR®. We spell that out on the quote, opening by opening.
