Energy Ratings

Energy Rating (ER)

Energy Rating (ER) for a window or a door is calculated using a formula that balances a product’s U-factor with its potential solar heat gain coefficient (SHGC) and its air tightness regardless of the manufacturing or assembly method and the materials used.  The higher the ER number, which typically ranges from 0 to 50, the more energy efficient the product is.

Windows and doors don’t consume energy but they can be the major cause of heat loss in homes and buildings. You will have to spend more for your heating and cooling needs if your windows or doors don’t insulate the outside temperature properly.

In Canada, energy efficient windows and doors are identified through labels with the Energy Star symbol. Energy Star is managed and monitored by the NRCan’s OEE (Natural Resources Canada’s Office of Energy Efficiency).

The Energy Star label also indicates if the window or door is suitable for the climate zone where you live.  See Canada’s Energy Star map that shows the four climate zones (A, B, C and D).  Based on the climate zone map, choose the type of window or door that is rated for your area’s climate. It is better to buy windows and doors that are considered suitable for more than one climate zone.

Purchasing the right ENERGY STAR rated windows and doors will give you potential energy cost savings of up to 40%.  Learn more about energy efficiency ratings at the NRCan OEE website.

Testimonials
  • I am proud to recommend Euro-Tech Windows. I am a research Engineer for a majour Canadian company. I researched energy efficient windows for the better part of 10 months before selecting Euro-Tech as ‘by far’ the most energy efficient windows available. I selected triple pane windows with solar glass which would give me both cold & heat protection. My home was uncomfortable with it’s temperature differences from room to room and it was expensive to heat due to the hill top location of the home. Euro-Tech triple pane windows gave me exactly what I expected from a quality product, comfort!

  • It is not easy for me to write these comments about my window purchases. I had a quote from Euro-Tech Windows in 2008. While the quote process was very informative and educational, I selected another company because the price was about 10% less than Euro-Tech. I have to admit that I did not heed the advice of the Euro-Tech consultant and check out the quality of all quotes on the government web site, I shopped solely on price. Now here it is two years later and I have called Euro-Tech to come out and to take out my two year old windows. I had made a very expensive mistake, my cheaper replacement windows were colder and far noisier than my 30 year old windows. I purchased new windows from Euro-Tech, this time I followed the consultants advise and upgraded to triple pane windows. They are exactly what I thought I would have had from the cheaper company; much warmer in the winter, cooler in the direct sun of the summer and FAR quieter due to triple pane technology. Yes, I bought windows twice in a two year period, but I am far happier having spent that little extra to get a great deal more.

  • I am a full-time LEED engineer, I recommend the best ways to save energy to building designers & engineers. I searched the internet for the most energy efficient windows available anywhere when I was planning to change my second home into an energy efficient showplace. After comparing all the available energy efficient windows I selected EURO-TECH WINDOWS as having all the features I sought. The consultant was knowledgeable and helped in selecting options that were best for my location. I will be recommending Euro-Tech Windows to professionals & homeowners alike as outstanding value for the cost.

  • I recently had my windows replaced by Euro-Tech windows. Your window consultant was extremely helpful and taught me what to look for when purchasing windows. I had other companies give me quotes and I checked the quality they offered. The comparison was definitely in Euro-Tech’s favour. I am retired and consider myself very frugal. Having to pay a bit more for top quality windows was by far the right decision as I did not want to have to replace lower quality windows again in 5 to 8 years. The high efficiency Euro-Tech windows will give me the comfort level I want. I was impressed by the energy savings, explained to me by your sales representative. The installers were very professional and did a fast and efficient job. When they were finished, my home was left in pristine condition, cleaned up with no mess left, just as it was when they started. I thank you Euro-Tech for the high quality windows and the fast and professional installation you did for me. I had Euro-Tech back a few months later to install more windows.
