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 a Good Investment?

YES! Energy efficient windows are an excellent choice for your Oshawa home. As a lakefront city, Oshawa is known to experience extreme weather conditions, especially in the winter. Having properly insulated, double- or triple- glazed energy efficient windows can make all the difference when it comes to climate control and major savings. Even though the Ontario energy rebate program is unfortunately no longer around, energy efficient windows have still been proven to make a positive impact on your energy bills and HVAC spend.

Thinking of selling your home? Energy efficient windows are a great value-add to any property. Impress prospective buyers with a major upgrade on your home, and pass on the energy savings to future homeowners.

Why Choose Vinyl Windows in Oshawa?

There are many reasons to choose vinyl windows for your Oshawa home. Vinyl is a very versatile material, flexible and airtight enough to tightly seal any opening, and with such low heat transference, vinyl windows beat out many other window types in terms of energy efficiency. Aesthetically-speaking, vinyl windows come in a range of colours, and can be painted to match your home’s décor.

What is the Cardinal Glass Difference?

All Thermo-Bilt products are crafted exclusively with Cardinal Glass. Cardinal glass is not only beautiful, it offers high insulation value, repelling cold air while retaining hot air in the winter, and rejecting heat and sunrays in the summer. Cardinal Glass is also uniquely self-cleaning, coated with a special coating that uses the power of UV rays and rain water to eliminate and wash away dirt and grime. All Cardinal Glass products are Energy Star® compliant, meaning that energy efficiency is high on the priority list.
