Single Hung Window

Single hung windows are some of the most popular replacement windows in Toronto, being the go-to choice for new home builds, retrofits, and renos. Similar to double hung windows, but with only one opening sash, these energy efficient windows are affordable, durable, and versatile, fitting best in rooms with little wall space, such as bedrooms, bathrooms, porches, and storage spaces.

Single Hung Windows Toronto

While single hung windows are generally considered the most straightforward replacement window for homes (and therefore more economical), Thermo-Bilt’s windows offer even more value through the replacement glass we use. We’re one of the select Toronto window companies that use Cardinal Glass, a tech-forward glass that protects against common and expensive seal failure problems. Cardinal Glass offers an industry-leading 0.2% seal failure rate, meaning better energy efficiency and thermal performance than any other windows you’ll find in the GTA.

Thermo-Bilt Reviews

We purchased 10 energy efficient thermal pane windows and two doors in March. The representative Mr. Barry Liburkin did a fantastic job explaining the benefits of his products. We were very happy with the installation team led by Stan and Igor. The office staff was also very friendly and we will gladly refer this company to everyone for their windows and doors needs. A job well done! Thank you.

Fantastic windows and installation services! Staff were prompt, courteous, and skilled. These windows are definitely high quality but the costs were affordable. Make a point of calling this excellent company.

We are very pleased with this company. They replaced 8 Windows in our house. Peter and his crew did a masterful job on our Bow window build. The job was done fast and efficient and we love the high quality of the product.
