  1. What does the R-value of a window mean?
    R-value measures the resistance of thermal transfer or heat flow through the window. The higher the R-value the better. A typical R-value for the centre of a double glazed window is R2. When Low-E and argon gas are added, the R-value typically doubles to about 4, reducing heat loss by approximately 50 per cent.

  2. What are the benefits of an energy efficient window?
    Energy efficient windows increase the comfort level in your home by reducing cold drafts and making a house feel warmer in the winter and cooler in the summer. They help control condensation because the interior surfaces of energy-efficient windows stay warmer, allowing you to maintain a higher level of humidity without worrying about condensation on your windows. They also last longer because condensation can cause premature deterioration of windows, walls and finishes leading to high maintenance and replacement costs. Most importantly, energy efficient windows save a lot of money. By minimizing air leakage and improving thermal performance of your windows, you could reduce heat loss through windows by up to 50 per cent and reduce your energy bills.

  3. How much money can I save by installing energy efficient windows?
    On average it costs Canadian homeowners approximately $1,200.00 per year to heat a home. Of that, industry standards indicate that about 25 per cent or $300.00 is due to heat loss through windows, if the windows are standard double paned units. By replacing drafty, old windows with energy efficient windows like Window Wise approved units, a homeowner can save almost 60 per cent of their energy costs, or $180.00 a year.

  4. Wood, vinyl, fiberglass, metal... Which is best?
    Frames and sash are manufactured using a variety of materials. Each material has its strengths and weaknesses and it is important to remember that good quality windows can be made from any of these materials as long as they are designed properly. Vinyl windows command the largest share of the window market because of their low maintenance, energy-efficiency, durability and competitive cost
