What makes windows energy efficient?
Are you thinking about replacing your windows? If so, it’s important to choose wisely. It can be tempting to opt for the least expensive models, but by choosing energy-efficient windows that are well made, you’ll save money on your heating and cooling bills. Here’s what makes some windows more energy-efficient than others.
- Multiple panes.
Two or three panes of glass with air or gas between them are better at insulating than a single pane. Multi-paned windows therefore help regulate the temperature in your home by preventing air exchange with the outdoors. They also keep out sounds, which is a plus if you live on a busy street.
- Gas fills.
While the space between the panes of glass in a window may look empty, there is in fact a layer of gas that’s been injected inside. Energy efficient windows have argon, krypton or other gases between their panes. These insulate better than plain air, and are non-toxic, odourless and colourless..
Newer windows have low-emissivity (low-E) coatings, which help to prevent heat loss in the winter and keep cool air inside during the summer. This coating also helps to block UV rays, thereby protecting your carpets and upholstery from fading.
Though you can find frames made of wood and aluminum, ones made of vinyl or PVC tend to be better at insulating. Vinyl offers the highest level of insulation and comes with the added benefit of being affordable and easy to maintain.
Finally, even top-quality windows won’t do much good if they’ve been poorly installed. Let the team at Canadian Comfort Windows & Doors in Ottawa ensure that the job gets done right.
- Energy efficiency rating
Wondering how to tell if your new windows are energy efficient? All you have to do is look for the Energy Star rating. This symbol marks products that have been tested by an independent and accredited agency like the Canadian Standards Association (CSA) for a variety of factors including the energy rating and rate of heat transfer.
In short, if a window has an Energy Star sticker, you can be sure it’s an energy-efficient and high-quality product.
