Why Choosing Energy Star Certified Windows & Doors

When comes to choosing new or replacement windows and doors, we all have our own preferences. Having said that, if saving money and being more eco-friendly are high on your agenda, then the first thing to look at when choosing a window or door is whether it has Energy Star certification.

"ENERGY STAR" certified products meet strict technical specifications for energy performance and are monitored by federal government. Here are some of the benefits for choosing ENERGY STAR certified windows and doors:

  1. Increased energy efficiency: Windows, exterior entrance door and sliding patio door can all be a significant source of energy loss in your home. In cold climate such as Quebec, this means higher energy bills for you. On average, ENERGY STAR certified windows are about 20% more energy efficient than the regular ones, while ENERGY STAR certified doors are about 15% more efficient, according to Natural Resource Canada.

  2. Improved comfort: With better insulation, ENERGY STAR certified windows and doors can help improve the overall comfort of your home. You may experience less heat loss, less drafts, and more consistent temperatures throughout your home. This is an important element to consider with more and more people are now working from home.

  3. Reduced condensation: ENERGY STAR certified windows and doors can help reduce condensation on the glass, which can help prevent moisture buildup and reduce the risk of mold growth.

  4. Environmental benefits: By choosing ENERGY STAR certified windows and doors, you can help reduce greenhouse gas emissions and other pollutants associated with energy production. This can help protect the environment and contribute to a more sustainable future.

  5. Enhanced curb appeal: ENERGY STAR certified windows and doors are available in a wide range of styles and designs, so you can choose the products that best fit your home's aesthetic. They can also help enhance your home's curb appeal, which can improve its overall value.

Key features to look for when choosing energy efficient windows and doors such as those certified under Energy Star certification according to Natural Resource Canada:

  • Special coatings: known as low emissivity coatings, or “low-e glass”. The lower the e- value the better insulation and less condensation on the glass. 

  • Triple glazing: for better exterior noise reduction and even more energy savings.

  • Window gas fills: Special inert gases between the glass panes rather than simple air for better insulation.

And equally important: 
  • Make sure to hire professionals to install your windows or door. Poor installation may cause condensation, cold drafts or even allow water to leak into your home. The damage water can cause is usually invisible until it is very costly to fix.

  • Take advantage of the government incentive programs to purchase your windows and doors. For the residents and business in Quebec, we have the following programs:
