What Is the Purpose of Thermal Windows?

If you’ve been shopping for windows recently, you’ve likely come across the term “thermal replacement windows.” Unless you are a window expert, you are probably wondering what a thermal window is. The phrase “thermal windows” can refer to a historic type of window that was used in ancient Rome (also called Diocletian windows), but today, the phrase is more commonly used in reference to energy-efficient windows. Whether you are looking for Diocletian windows or energy-efficient windows, Quality Window & Door can help.

About Diocletian Windows

Diocletian windows are a type of arched windows that were commonly used in the public baths of ancient Rome. They fell out of usage after the fall of the Roman Empire but have started to regain some popularity today. Diocletian thermal windows are large semicircular windows that are broken into three window compartments. Although they can vary slightly in appearance, they generally look like this:

Today, these windows fall within the category of special shape windows or geometric windows for many window manufacturers. Diocletian windows can give your home a distinctive look that will be the envy of your neighborhood.

If you are interested in having windows of this style installed in your home or business or would simply like to learn more about our arched window selections, visit one of our window showrooms or schedule an in-home consultation today!

About Energy-Efficient Thermal Windows

Chances are, you are looking for energy-efficient thermal windows rather than the ancient Roman variety. Energy-efficient thermal windows are double or triple-paned and have features that are designed to improve the energy efficiency of your home or business. These windows are typically filled with an insulating gas such as argon or krypton—designed to slow the transfer of heat into or out of your home or business. This means lower heating and cooling costs! In fact, upgrading to energy-efficient thermal windows can help you reduce your heating and cooling costs by as much as 40 percent!

At Quality Window & Door, we carry a variety of energy-efficient thermal replacement windows from many leading window manufacturers. Whether you are looking for wood windows, vinyl windows, or composite windows, we have energy-efficient thermal windows that will meet any home’s unique design needs.

Great company that backs their product. We built a new house and Quality Window & Doors was the subcontractor for our Weathershield windows and doors. Wayne and Noe came out to service a broken handle on our 16' Weathershield sliding door. We were technically beyond the warranty period but they repaired the handle for free. They also took the time to go around and adjust our other exterior doors to make sure they were well aligned now that the house had settled a bit. Wayne was a real expert and got all the doors adjusted and working perfectly!

We are thrilled with our new windows and door! Excellent job from estimate to completion! The install team was fantastic and I loved that the lead installer was also present during the initial measurement phase. It took a few months for the windows to arrive so it was really nice to see a familiar face for the install and he knew exactly what to do! Highly recommend!!

QWD is a first rate company. The staff from product selection, estimate, showroom, measurement and installation were professional and highly competent.
