FAQs
Are Energy Efficient Windows a Good Investment?
Energy efficient, eco-friendly windows are an excellent choice for your Richmond Hill home. In a city with such extreme weather conditions, we know that you’re always looking for ways to lower your energy bills and HVAC costs. Energy efficient windows happen to be great for both! Designed in a way that maximizes climate control and minimizes air flow in and out of the house, eco-friendly windows mean that your air conditioning and heating units will never have to work as hard.
Thinking of moving at some point in time? Energy efficient windows can do wonders for your home’s curb appeal, increasing your property’s value and making it an easier sell to prospective buyers.
Why Choose Vinyl Windows in Richmond Hill?
There are many materials to choose from when considering a window replacement, but in many ways, vinyl comes out on top. Vinyl windows are incredibly energy efficient for two reasons: they provide an air-tight seal between the window and its frame, preventing air from escaping and entering the home, and vinyl has low heat transference properties, meaning that cold or hot air from outside won’t affect what happens indoors. When combined with double- or triple- glazed glass, vinyl windows are the ultimate choice in energy efficiency.
Aesthetically speaking, vinyl windows are extremely versatile as well. Choose from a range of colours or simply paint over white vinyl, and you can easily match your home’s décor, even if it changes often.
The Cardinal Glass Difference
A major differentiator for Thermo-Bilt is Cardinal Glass products, an innovative glass-engineering company, goes into all of our products, which stands out from other glass manufacturers in the GTA and Ontario. Not only do they have superior insulation properties that block out heat, cold and UV rays, but they are also uniquely self-cleaning due to a special coating that’s added during the manufacturing process. Cardinal Glass is Energy Star® compliant, demonstrating the company’s dedication to energy efficiency.
