Energy Facts



 

Energy efficiency facts:

 

On average, Canadian homeowners pay $1,200 a year to heat their home. According to SAWDAC, “industry standards indicate that about 26 per cent or $300.00 is due to heat loss through windows” (SAWDAC).

“Canadian window manufacturers now lead the world in developing new technology. One example: argon-gas-filled, double-paned glass that provides remarkable energy efficiency and costs about 20 percent more than standard windows” (Maclean’s).

Energy efficient windows are extremely important in Canada given the extremes of our climate.

An energy efficient window guards against heat loss, cold drafts, and condensation, which effectively reduces HVAC (heating, ventilation and air-conditioning) costs. Most people give little thought to the efficiency of their windows, and don’t realize the difference a high quality, well-installed window can make.

During the winter, the sun’s low elevation in the sky at midday enables it to shine through south-facing windows (placement). These solar gains can help reduce your heating costs during the Winter (OEE).

Energy-efficient windows are least likely to have condensation. Their resistance to condensation, however, depends on the indoor humidity level. A humidity level of more than 40 per cent, when the outside temperature is -20 C or colder, may cause condensation even on a good performing window (OEE).

The heavy gas fills in high-performance windows, which reduce conductive and convective heat losses, also reduce sound transmission from the exterior to the interior. The greater the number of panes, the better the sound absorption (OEE).

Your window is made up of approximately 75% glass and 25% frame. The price of the window is 75% frame and 25% for the glass. Your heat loss and heat gain is concentrated in the glass part of your window. By now, you must have realized that the glass is a most important part of your window unit. A wall in a new home has an insulating value of about R10 to R20. There are now insulated glass units available that will give you R Values of up to 10!

An insulating glass R-Value of 2 (regular double pane) will not give you the performance required for a regular Ontario winter. Insulated spacers available in today’s sealed glass units can reduce the condensation that usually occurs on the bottom of your glass unit. A higher R-Value will increase your interior glass temperature, thus allowing for higher humidity levels before condensation occurs. Low-emissive coatings applied to glass surfaces can reduce the loss of radiated heat in the home.

With the increasing complexity of window technology, installation is not something you want to play around with. Unless you are an experienced carpenter, window and door installation is not a do-it-yourself project. A crack in a gas-filled window will limit its effectiveness- and you won’t have a warranty if anything goes wrong.

Performance


Where performance really counts for your windows.

 

Energy efficiency in windows and doors has been making a larger impact in recent years. Reducing energy consumption not only helps cut costs and improve comfort around the home, but it also reduces the release of harmful emissions to the environment.

 

Our windows maximize energy efficiency through fusion welding, weather-stripping, the types of glass used, as well as the low-emissive glass coatings. The use of Super Spacer insulating glass unit is also implemented, which provides optimal thermal performance and has the lowest U-Value in the industry.

 

What is Energy Star?



 

Energy Star is a joint program between the U.S. Environmental Protection Agency and the Canadian Department of Energy that protects the environment by mandating energy efficient products and practices. Certification from Energy Star can only be approved after vigorous testing from an independent laboratory. All Vinyl-Pro products not only meet but exceed Energy Star standards.

 

Understanding the Energy Star performance markers:

 

U-Factor

 

The U-Factor is a measurement of the amount of energy a material can conduct. In terms of windows, the lower the U-Factor, the stronger that window will resist to heat loss. The lower the U-Factor, the more money you will save over the winter months.

 

Solar Heat Gain

 

A Solar Heat Gain co-efficient is a measurement of the amount of solar radiation transmitted through a material. The lower your Solar Heat Gain co-efficient, the more ultraviolet (UV) rays will be absorbed through your windows. This is fantastic for saving money during the summer months.

 

Air Leakage

 

An Air Leakage rating is a measurement of the amount of air passing through cracks in the window. This affects both heat losses as well as heat gain. The lower the Air Leakage rating, the less air will pass through cracks in the window.

 

Energy Rating

 

Energy Ratings are determined through a combined analysis of the Solar Heat Gain co-efficient, air leakage and heat loss.
