Which level is right for you?

When shopping for windows and doors, choosing products with ENERGY STAR certification ensures you're getting energy-efficient, high-performance solutions. ENERGY STAR® is a trusted government-backed program that helps homeowners identify the most energy-efficient products on the market. For windows and doors, ENERGY STAR certification means the product has been tested to meet strict standards for:

  • Insulation - keeping heat in during winter and out during summer
  • Solar Control - managing how sunlight affects indoor temperatures 
  • Airtightness - Preventing drafts and leaks 

For homeowners, this translates into lower energy bills, year-round comfort, and a reduced environmental footprint - all while increasing the value of your home. 

ENERGY STAR - ER 34

Our ENERGY STAR - certified windows achieve an Energy Rating (ER) of 34.

What this means for you:

  • Strong energy efficiency at an excellent value
  • Reliable performance that meets Canada's national standards
  • Noticeable savings on heating and cooling bills
  • Greater comfort with fewer drafts and more consistent indoor temperatures 
  • Eligibility for Canada's Greener Homes Loan (CGHL), making upgrades more affordable.

These windows are a smart choice for most Canadian homes. 

ENERGY STAR Most Efficient - ER 40

For those seeking maximum performance, ENERGY STAR Most Efficient products go a step further achieving an ER of 40.

What this means for you:

  • Elite energy performance - among the top tier of windows in Canada
  • Superior insulation and tighter sealing for maximum comfort
  • Ideal for extreme climates or homeowners seeking the best long-term savings
  • Eligibility for Canada’s Greener Homes Loan (CGHL), giving you access to financing options that make investing in top-tier efficiency even easier

Choosing an ER 40 window means you’re getting the highest level of efficiency available today—with the added benefit of financial support through CGHL.

So, which is best?
  • ENERGY STAR-certified products are excellent for most homes and provide strong energy savings at a good value.
  • However, if you want the highest level of efficiency, greater comfort, and the potential for larger rebates, Most Efficient products are worth the investment.

Ultimately, choosing any ENERGY STAR-certified product is important. It ensures your home is more comfortable, more cost-effective to run, and better for the environment—all without sacrificing quality or performance.
