Windowsville offers an extensive line of glass options to choose from, ranging in the degree of light, privacy, and design. The following options are available:

low-e glass sliding doors


An elegant and smart choice for any patio door is energy-saving Low-E coated glass. Its advanced coating allows the warmth to stay indoors when it's cold, and prevents the sun's rays from making your home too hot during the warmer months. Not only that, but the coating also protects carpets and furniture from fading - a great bonus!

Internal mini-blinds

Internal mini-blinds are an evergreen choice for those looking to add a refined touch to any room, while still providing control over the amount of natural light coming in and ensuring absolute privacy. Not only do these classic window coverings look great, but they're easy to use and require minimal maintenance - making them an unbeatable option for any home.

Sliding Doors Features

casement vinyl window construction

Vinyl Construction

Windowsville sliding patio doors are made from a unique, 100% lead-free Canadian-made premium uPVC. As a result, our windows withstand impact and discolouration better than the competition.

Easy-to-operate Screen

Our easily operable sliding patio door screens are placed on the outside of the door, where they best protect against insects and elements. Boasting a light construction and chic design, these screens are strong and secure with their aluminum frame and fiberglass mesh. They are lockable, offering both protection and maximum airflow. The perfect combination of form and function!

tempered glass sample

Tempered Glass

Tempered glass is often called safety glass due to being 4 to 5 times stronger than ordinary annealed glass, which makes it much more resistant to force. It is heat resistant and its thermostability is twice that of regular glass, meaning it can withstand higher temperatures. Should the glass ever break, it does not separate into large and dangerous shards like regular glass does, but shatters into small pieces, significantly reducing the risk of injuries, especially for young children.

Argon gas filling

The inside of the thermal glass unit is filled with argon instead of air. Argon is an inert, odourless, safe gas, which is denser than air. As a result, our sliding patio doors provide reduced inter-pane convection and yield improved thermal insulation efficiency. Coupled with the Low-E coating, Argon brings the temperature of the door closer to room temperature, while also offsetting water vapour to prevent condensation.

warm edge super spacer

Warm Edge Spacer

The non-metal, structural foam spacer is the seal that keeps the glass unit in place. The dual-seal unit combines the sealant that performs the adhesive function and the second sealant which has moisture and vapour resistant properties. Both sealants perform well in both high and low temperatures, and withstand height humidity and ultraviolet exposure.

Interior Finishes

Vinyl casings are an ideal solution for an enhanced look in your house. Vinyl is a perfect material for a casing because it does not deteriorate, chip, fade, or rot with time. We provide advanced technology with the finest materials for durable, flawless finishes that will retain their original colour overtime. There is a variety of options when it comes to selecting rosettes (trim corners), that will add a unique look to your sliding patio door.

Double and triple-pane insulated thermal units

Our sliding patio doors can come with two or more layers of glass joined in a completely triple-sealed thermal unit which provides an effective barrier to heat, humidity, and sound transfer for optimal comfort.

casement window integrated brick molda

Integrated brickmold

A brickmold is an exterior trim of the sliding patio doors, framing it like a picture. It is used to fill the gap between the door and the exterior surface (stone, siding, brick, stucco etc.) while aesthetically providing a richer look. We provide various sizes and styles of brickmolds, which can be bent into shapes.

Low-E Glazing Options

Low-E coating is not visible for most of its grades and lets the most visible light through, and it provides year-round solar control and comfort in all types of weather. In hot weather, it rejects the sun's heat and harmful UV rays. In cold weather, it reflects heat back into the room. Different levels of Low-E coating are available.

Frequently Asked Questions About Sliding Doors

You will need to measure the width of your doorway. Measure the total opening of the door frame, including moulding and other trim around it. Check to make sure that the width of your doorway is larger than the width of the sliding door you want to install.

Yes! Sliding doors can help keep your home comfortable by providing an additional layer of insulation against drafts while still letting light in during sunny days - essentially creating a "greenhouse" effect within your home during cold months! 

Sliding doors typically require minimal maintenance, mostly consisting of checking the hardware to ensure it is properly secured and lubricating parts when necessary. Additionally, occasionally wiping down the door with a damp cloth will help preserve its appearance.

This depends on the size and model of the sliding door being installed, as well as the type of opening it is going into. Generally speaking, most sliding doors require at least twice their width in order to open fully without obstruction.
