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.
