Windows play an important role. They allow in natural light, increase ventilation and help beautify the space they occupy. Here are some additional benefits of replacing your windows:

    They’re more secure. New windows are built to be strong and are therefore less susceptible to burglary and break-ins. Many have advanced locking mechanisms as well. Plus, if your window happens to break, the glass is tempered and therefore designed to shatter into small, dull-edged pieces rather than large, dangerous shards.

    They’re more energy-efficient. Replacing your windows can help you reduce your energy bills. When properly sealed and installed, modern windows offer superior insulation. This helps keep your property cool in the summer and warm in the winter.

    They’re aesthetically pleasing. Choosing the right replacement windows can improve the curb appeal and value of your property.

    They block out UV rays. Most modern windows come with UV protection, which helps prevent your furniture, flooring, countertops and artwork from becoming discoloured. In addition, replacing your windows with ones that are UV-resistant can help prevent premature skin-ageing.

If your windows are drafty, have rotten frames or are difficult to open and close, it may be time to replace them. The team at Canadian Comfort Windows & Doors would be happy to help.
