Windows, Doors & Sealed Units

Poor installation, years of hard use, shifting foundations and seasonal warping can often force windows and doors to become out of square with their frames, resulting in energy loss up to 25% in your home. In Canada’s climate, this means higher energy bills for you.

HAT Smart defines a Sealed unit as a sealed window unit which is part of an advanced glazing system that features two or more sheets of glass separated by an adhesive spacer and filled with air, argon, or krypton. The whole unit is then sealed along the edges to prevent a vacuum or gas from leaking.

Criteria

To qualify, each window must have a U-Factor rating between 1.05 and 1.22 W/m²K. The U-Factor is the rate of heat transfer from warm to cold areas. The lower the number, the more efficient the product.

Rebate amount

Rebates amounts are per rough opening; windows are also based on the U-Factor of the new installed unit.

$100 for new energy efficient doors
$125 (1.14 ≤ 1.22 W/m²K)
$150 (1.05 ≤ 1.13 W/m²K)

Maximum rebate: $2,500
