U-VALUE – (Heating Energy Loss)

Measures the rate of heat loss through glass and other products. The lower the U-Value the better the insulating qualities of the glass which will reduce heating costs in the winter as well as keeping the interior glass surface warmer which will reduce the likelihood of any glass condensation.

What is the GreenON Rebate Program?

In mid-December, the Ontario government launched a new program offering rebates on the purchase and installation of select high-performance windows. This program, called GreenON, was created to promote the reduction of energy costs and fight climate change. It offers $500 per window replacement, and up to $5,000 per house.

About the Program

  • Available for single homes, semi-detached and townhomes already built (not on new construction).
  • Available on full-frame installation only (no retrofit installs allowed).
  • Bay and bow windows are eligible (but a bay/bow counts as 1 opening).
  • Registered Heritage homes: GreenON is working on the parameters of the program.
