FAQs
Are Energy Efficient Windows a Good Investment?
In a word, absolutely! Energy efficient windows are not only good for the environment, they’re great for your bottom line too. By preventing outdoor air from entering the room and indoor air from escaping, energy efficient windows make climate control in your home a breeze! (Without the actual breeze.) Investing in these replacement windows will help you save on your monthly HVAC and energy bills, lowering heating costs in the winter and cooling costs in the summer.
Aside from function, energy efficient windows add curb appeal to your home. Prospective buyers will be impressed by your replacement windows, as well as the savings you’ll be passing on to them.
Why Choose Vinyl Windows in Mississauga?
Vinyl windows are an excellent choice for your Mississauga home. Not only is vinyl more customizable than other window types, meaning your windows don’t have to stick out from the rest of your home’s design, they’re also more cost effective and energy efficient. With superior air tightness sealing your home off from the world outside, vinyl windows are a wise choice for your wallet, too.
The Cardinal Glass Difference
Cardinal Glass is Thermo-Bilt’s first choice for windows and doors, every time. Uniquely self-cleaning due to a special coating added during manufacturing, you will rarely have to spend time or money on cleaning your replacement windows. Cardinal Glass is fully Energy Star compliant, largely due to its superior insulation value.
