What to Look for in a Replacement Window

There are a few reasons you might be considering window replacements. For one, your windows may not work quite like they used to – they’re drafty and cold-to-the-touch. They might feel flimsy, offering little protection against intruders. Or, your windows might simply look dated, in need of a curb-appeal-improving facelift. 

Whatever the reason, you want to ensure that your new windows make an appreciable difference in your home. To do that, you need to source quality windows and doors from a company that knows how to install them properly. Sounds straight forward, right? 

Unfortunately, not all homeowners know what they’re looking for. If you feel a little lost in your search for quality replacement windows, you’ve come to the right place. Here are a few key features to look for in a new window. 

Energy Efficiency

Energy Efficiency should be your top priority. It’s an indication of quality construction, solid materials and proper installation. 

Windows have the potential to be a major source of energy loss in your home – up to 30% according to Energy.gov. Low-quality, improperly installed windows could leave you paying a handsome premium on your energy bill, which is why it’s wise to shop for efficiency. 

Choose a window replacement company that partners with ENERGYSTAR and lists “energy ratings” for each of its products.. 

Noise Reduction

When shopping for windows, consider sound insulation. You want a window that does a decent job blocking outdoor noise for those times when your neighbour is having a raucous outdoor BBQ. 

In general, double-glazed windows do a good job of reducing sound transmission. If you’re serious about noise reduction, however, choose a triple-glazed window. That extra pane of glass and argon fill really helps buffer sound. 


According to home security experts, burglars often look for points of weakness in a house. If the door seems solid and secure, they head for the windows. Often, they don’t even “break in” – they merely exploit the weakness of a lock to open the window. 

To deter burglars, look for a window with a multi-point locking system. In most cases, a sophisticated locking system will suffice to discourage a would-be intruder. If you’re worried about a burglar breaking the glass, you may consider triple-glazed windows. 


With efficiency, noise reduction and security covered, you can turn your attention to looks. Obviously, you want a window that looks great in your home, one that fits the architecture and décor. 

Before you settle on a window company, make sure that they can customize their products. You should be in charge of the size, shape, grille style, colour and hardware of your new windows. Otherwise, you may end up with a product that seems out of place. 

If you are on the market for new windows, take these key features into consideration. Ultimately, what you want is a window that lowers your energy bills, reduces sound transmission, improves security and looks fantastic. That isn’t too much to ask!
