FAQs
Are Energy Efficient Windows a Good Investment?
Yes, energy efficient windows are absolutely worthwhile! They not only look great, but their performance is unparalleled. Although the Ontario energy rebate, GreenON, has been dissolved, energy efficient windows still come with a host of savings. When properly installed, they seal your home off completely from the outside world, meaning less drafts, less condensation, and less money wasted on heating and cooling. Double- or triple-glazing, vinyl, and energy-efficient frames all combine in lowering your monthly energy bills.
Apart from function, energy efficient windows can also be great when it comes to selling your house. As residents in one of Toronto’s most affluent suburbs, Oakville-ites know that any upgrades that can increase the value of your property, are a good idea.
Why Choose Vinyl Windows in Oakville?
As mentioned above, vinyl windows are fantastic when it comes to energy efficiency. Extremely air tight, vinyl acts as a firm seal between your home’s exterior and interior. Unlike aluminium, for example, vinyl doesn’t allow for any heat transference, meaning the material won’t be affected by heat or cold coming from outside. With all of these benefits you would think that vinyl is more expensive, but it is actually more cost-effective than many other materials!
What is the Cardinal Glass Difference?
