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.

Thomas Reinboldt

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.

Natalie M

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.

FAQs

Are Energy-Efficient Windows and Doors a Good Investment?

Despite the end of the Ontario energy rebate program, GreenON, energy efficient windows are still a wise choice for your Markham home. When it comes to the bottom line, our Markham window installers will tell you that replacement windows and doors that are energy efficient can make a big difference. Having older, poorly-sealed, drafty windows can take a big toll on your energy savings. With unpredictable and extreme weather conditions in Markham, energy efficient windows and doors are not just a luxury, they’re a necessity.

Apart from practicality, energy efficient windows can also increase the value of your home. As prospective buyers search for a new place to live, energy efficient windows are sure to make an impact on their decision.

Why Choose Vinyl Windows in Markham?

If you’re stuck deciding between vinyl and other window materials for your Markham home, we can give you several reasons to choose vinyl windows. One of the biggest pros of vinyl windows is their exceptionally long life expectancy; compared to other window types, vinyl windows have been known to outlast. Not only do they outlast, but they also outperform; in terms of energy efficiency, for example, due to their superior insulation and air-tight construction, vinyl windows are excellent at stopping outdoor air from coming in, and indoor air doesn’t escape. Aesthetically speaking, vinyl windows are also much easier to paint and re-paint, depending on your Markham home’s overall décor.

What is the Cardinal Glass Difference?

A key distinction between Thermo-Bilt and other windows and doors replacement companies is our use of Cardinal Glass for all of our products. Cardinal Glass, an innovative glass manufacturing company, is on a mission to design and fabricate the most advanced residential products in the industry, and we believe they’ve been wildly successful.

Cardinal Glass sets itself apart from most other replacement window glass companies through:

  • Superior insulation that reflects warm air back in to the home throughout winter, and prevents damaging UV rays from entering on sunnier days
  • A special coating that allows the glass to clean itself through the power of UV rays
  • Full Energy Star® compliancy
