Triple-glass windows have become an extremely popular option for modern Canadian homes. With temperatures reaching all-time lows, Canadian winters can get pretty extreme, which is why homeowners often opt for the ultimate protection that is only offered by triple-glass (or triple-glazed) windows. They’re durable, tough, and can endure the harsh Canadian climate. But what makes these windows so special? In order to get a full understanding of why triple glass windows are so popular, we first have to understand how windows are evaluated in the first place. Here’s what determines the quality of a window:
In Canada, windows and doors are tested using particular standards and values that are determined by the Canadian Standards Association, including:
- Energy rating - measures the balance between the U factor, solar heat gain and air leakage. Energy rated windows and doors bear the energy star label, which means their energy performance was certified by an accredited agency in Canada.
- The U factor or heat transfer.
- Solar heat gain or how much of the sun’s heat can pass through the window.
- R-Value or resistance to heat transfer.
- Centre-of-glass rating that only refers to the glass portion of the product.
- Visible transmittance or how much light can pass through the product.
