Vinyl Windows & Doors

At Clera Windows and Doors, we built our products with only the best types of vinyl; this adds to the distinctiveness of our products, making us one of Canada’s major producers and installers of replacement vinyl windows and doors. We have a wide range of inventory for you to browse, both classic and modern.

Our highly trained and certified staff will help you get the right door and window replacements for your home or office. There are many things you need to consider, in addition to your personal preferences, such as existing building code requirements. Different technologies may also affect your choices. Double or triple pane windows, for instance, have heavier glass and wider frames, and are typically supplied in smaller sizes, unlike single-pane windows that come in very large sizes.

Still, there are numerous styles and technologies to help you create a custom door and window with the exact features you are looking for.

We prefer vinyl for a variety of reasons. It is able to retain its shape through a rough climate without degrading its capacity to retain its shape. It’s very inexpensive, too, making vinyl a sensible choice. You don’t have to invest a ton of cash to maintain your doors and windows to look beautiful and clean in Mineola.

High R-Value is also one of the reasons why we like vinyl. It is capable of regulating the temperature of the room because it is very efficient in keeping back heat waves. It’s also a lightweight element that makes it easy to install.

As the main choice for the residents of Mineola and adjacent areas, we built our vinyl doors and doors to meet your particular demands. We trained our workers in our special course, under the surveillance of the Canadian Standards Association. We are committed to ensuring that you have the biggest and most complete control over our products.

Meet the Team at Clera Windows & Doors in Mineola

Clera Windows and Doors is a family-owned business that focuses on customer performance and affordability. We have focused more on offering you with the biggest possible experience. Our products are designed to meet the particular requirements of our clients. We’re trying to please our customers with our services. That’s why we’re attempting to build our replacement doors and windows to be both environmentally friendly and pleasant to look at.

Our custom windows are manufactured with consideration of the newest technologies that can be useful to our clients in different environments. For instance, our self-cleaning windows use Pilkington Active, which is manufactured using the same advanced pyrolytic technology as glass panels for photovoltaic solar cells and electronic applications, and applied to one surface of clear float glass to make your windows stay cleaner longer – often for their lifetime.

Clera custom windows also use argon, low-e glass, and warm edge spacers to improve the energy efficiency of our windows, reduce condensation, prevent harmful UV radiation passing through, prolong the life of your new window replacements, and improve environmental friendliness.

Our double and triple glazed windows are filled with argon gas between the panes to improve insulation by reducing the transfer of heat and cold through the window. Using low-e glass gives nearly the same insulation effect as having an extra pane of glass.

Combining low-e glass with argon gas gives you twice the energy efficiency of clear glass. While some of the gas will leak over time, Argon is an inert, non-toxic gas that occurs naturally in the atmosphere. It is completely safe, plus the leakage is very minimal – you can expect a 10 percent loss over the course of two decades.

With our group of specialists, we guarantee that the product you’re purchasing is what you’re searching for. If you’re going to replace your windows and doors, we can provide you with free inquiries about your next projects. Drop by our nearest place in Mineola and we’re going to help you out!
