The company received Special Recognition in 2024, then won Manufacturer of the Year for Fenestration Products and Promotional Campaign of the Year in both 2025 and 2026. "We do not take this for granted," said Harry Sunner, CEO of Durabuilt Windows & Doors. "There are much larger manufacturers in this program, and any one of them could have won. We just try to build the best window we know how to build, and to keep getting better at it. Being recognized twice in a row is humbling. I would like to recognize our whole team and congratulate them on this achievement. Every department has a hand in this, from the plant floor to engineering to the people who install the windows and doors. It also goes to the dealers, builders, contractors, partners and homeowners who trust us with their projects." A national program built with local partners The 2026 awards recognize work carried out in 2025. That year Durabuilt shipped over 90,000 ENERGY STAR(R) certified window products across Canada. The company introduced the ENERGY STAR(R) Most Efficient and High Efficiency symbols on qualifying products, so homeowners can spot the highest performing options at a glance. Reaching those homeowners took a coordinated national effort. Durabuilt worked with hundreds of retail and dealer locations in nearly 200 Canadian communities to promote ENERGY STAR(R) certified products. The company expanded into British Columbia through new dealer partnerships and premium Delta Fiberglass product lines, with further provincial growth planned. Durabuilt also worked to put higher efficiency windows within reach of more homeowners. Two Free Triple Pane Upgrade campaigns, one in spring and one in winter, made triple pane available as a complimentary upgrade. The company helped homeowners access the Canada Greener Homes Loan by connecting them with the pre-retrofit energy evaluation the program requires. "Most people buy windows once or twice in their whole life," said Henny Sunner, Director of Marketing and Renovation Channel at Durabuilt Windows & Doors. "It is a big decision, and the information can get overwhelming fast. Our goal was to make the efficient choice, the easy choice. If a family ends up in a more comfortable home with a lower energy bill, the campaign did its job." Every Durabuilt window and door is built to meet or exceed ENERGY STAR standards. From the Alpha and Omega window lines to the premium Delta Fiberglass line, every product is engineered to reduce energy loss, improveyear-round comfort, and help Canadian homeowners save on heating and coolingcosts. "Two years in a row sets the standard we musthold now," says Henny Sunner. "We are growing in British Columbia, and the goal remains the same. A homeowner should be able to walk into any dealer we work with, get a straight answer, and end up with a window that is efficient and genuinely well made. Efficiency matters, so does how the windowlooks and how long it lasts." About Durabuilt Windows & Doors.
