FAQs
Are Energy Efficient Windows a Good Investment?
With the hyper-competitive real estate market in Toronto, any investment that adds value to your home is a good one. Energy efficient windows are a considered a major upgrade, and a valuable addition to your Toronto home.
Although no longer eligible for the Ontario Energy Rebate Program, GreenON, energy efficient windows have been proven to lower energy bills and HVAC spend significantly. Designed for climate control and low heat transference, your new windows were made to prevent drafts, breakages, and leaked air. You will never feel the cold in harsh Toronto winters, or the beating sun of stuffy Toronto summers.
Why Choose Vinyl Windows in Toronto?
Vinyl windows are a great choice for your Toronto home for several reasons. First off, they are extremely energy efficient, creating an air-tight seal between the glass and the frame. Unlike other materials, such as aluminium, vinyl doesn’t transfer heat, meaning that your home won’t be susceptible to weather conditions regardless of what’s going on outside. Aesthetically speaking, vinyl is easily customizable; choose from an array of colours, or simply paint over white vinyl to achieve the desired look for your home. Surprisingly, despite all of these benefits, vinyl windows are also more cost-efficient than many other types of home windows.
