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?

Although the GreenON Ontario energy rebate program has unfortunately expired, energy-efficient windows are still a wise investment for your home. After a window installation for your Ajax home, you’ll start to see a drastic impact on heating, cooling, and other energy bills. By keeping the warmth or cool air emitting from your furnace and air conditioner, respectively, in your home, you’ll save a noticeable amount on HVAC costs.

A window replacement also adds curb appeal to your home, increasing its overall value. When the time comes to move, you should easily make back the amounts you invested in your Ajax home’s energy efficient windows and doors.

Why Choose Vinyl Windows?

Vinyl windows come with a long list of benefits. First of all, the life expectancy of vinyl windows far exceeds most other materials available on the market. Aside from being long-lasting, vinyl windows are also incredibly energy-efficient, consistently shaving off heating, cooling, and other HVAC costs in your Ajax home. Vinyl windows offer a lot of room for customization as well. This material can easily be painted to match the overall aesthetic of your home, and it will not fade in the sunlight even over long periods of exposure

What is the Cardinal Glass Difference?

All of Thermo-Bilt’s replacement windows and doors are built with state-of-the-art Cardinal Glass, an innovative glass manufacturer whose mission is to design and fabricate the most advanced residential glass products in the industry.

Cardinal Glass is engineered to deliver the perfect balance of solar control and visibility, while providing the highest levels of year-round comfort and energy savings. Cardinal Glass’ superior insulation works hard to keep cold air out in harsh Ajax winters, and hot air out in the summer months. All Cardinal Glass products are manufactured with a special manufacturer’s coating designed to be self-cleaning, using only the power of the sun’s natural UV rays to keep your windows cleaner, longer. Due to Cardinal Glass’ excellent insulating value, all products are also Energy Star® compliant, meaning you can rest easy knowing that your windows and doors are certified energy-efficient.
