2.     Energy saving features of efficient windows

ü       Double paned - double paned windows create an air space between the panes of glass that acts as an insulator. Double paned windows are better than single paned windows because they reduce air convection (movement of air caused by differences in temperature). A thicker air space insulates better than a thin one, but increasing the air space beyond 1/2 inch provides no further gain in energy performance and convection loops might occur.

ü       Low-conductivity gas fill - By substituting the air between the panes of glass for another gas such as argon, heat loss can be greatly reduced. Argon is a denser gas that has lower conductivity than air. This means that the argon gas fill allows less heat to be transferred. It also prevents convection loops from forming because argon requires more energy to heat it and make it rise.

ü       Low-Emissivity coating - Low-E means lower heat exchange! Low-E glazing allows visible light to pass through but reflects infrared heat radiation back into the house. This means a warmer house in the winter and a cooler house in the summer.

ü       Low-conductivity warm edge spacers - The material on the edge moves the heat!   The edge spacer provides an air seal and holds the two panes of glass apart. Ask for warm edge spacers when buying new windows.

ü       Low-conductivity frames - The choice of window frame material plays a large role in the energy performance of your windows. Choose a material with low conductivity. Low conductivity materials are essential when it comes to keeping heat in. Vinyl is an excellent choice for frame material.

Remember, A Window Wise installation automatically includes all of the above features!!!

3.     Consumer Information

Although appearance, cost and resilience are important considerations, please ensure that you select a high-performance window that meets CSA standards and has a good ER number.  This quality of window will also tend to be better designed and manufactured and will offer better resistance to condensation.

What you should know:

ü       CSA certification eliminates companies that produce inferior products.

ü       CSA inspects our  supplier’s plants regularly to ensure compliance to certification.

ü       All our windows are CSA Certified - Above minimum requirements.

ü       Do the vinyl profiles have a smooth, high-gloss finish?

ü       How are the insulated units designed?  Are they engineered in such a way that there will be few insulated unit failures?

ü       Are the corners of both the frame and sash fusion welded?

ü       Is durability designed with double walls or internal screw bosses for mounting hardware?

ü       Does the glass have adequate insulating air space, thermally improved spacers, a low-e coating and other features that improve performance?

ü       Can the sash be tilted in and lifted out for easy cleaning?

ü       Have the frame and sash material been tested for colour stability and impact resistance?

ü       Are test reports available to validate the window’s resistance to wind, air and water leakage?

5.     Warranty

ü       Does the window come with a good warranty?

ü       What are the conditions, limitations and exclusions from coverage under the warranty?

ü       What is the warranty on labour?
