FAQs
Are Energy Efficient Windows a Good Investment?

Although the Ontario energy rebate program, GreenON, has unfortunately ended, eco-friendly windows still offer a host of savings for homeowners. Our window replacement experts will guide you through the benefits of energy efficient windows, explaining the insulation, double or triple glazing, vinyl material and high quality frames. All the characteristics of energy efficient windows makes them the best choice for your home as they contribute significantly towards lowering of your energy bills.
In addition to this when prospective buyers look at your house they see energy efficient windows as a major plus point.
Why Choose Vinyl Windows in Ancaster?
Vinyl windows are cost effective and energy efficient at the same time. Vinyl windows minimize the air flow, trapping indoor air and preventing outdoor air from entering your home. These windows are extremely customizable as they come in a variety of colours and can easily match the style of your home. As opposed to other windows types such as aluminium windows, vinyl windows won’t transfer heat or cold, resulting in lowering of your energy and HVAC bills.
