Because our windows and doors are always custom manufactured to project-specific requirements, we can design products to meet ENERGY STAR guidelines for any zone. Figures provided are for sample configurations: please contact us for more information and project-specific energy calculations.

Our standard products are ENERGY STAR qualified for all US zones and for Canada zones AB (shown above). Many Cascadia products also meet ENERGY STAR specifications for Canada zones ABC; some are qualified for all Canada zones ABCD (see tables at left).
