low e glass sliding door


Energy-saving Low-E coated glass is a simple, elegant option for your sliding patio door. This glass features a clear, high-tech coating helping to reduce heat loss by reflecting it back into the home in cold weather. In warm weather it provides the opposite effect of reflecting the sun’s rays to help keep the home’s interior cool. Energy-efficient Low-E coating also helps protect floors and furniture from fade damage. There are a few grades of Low-E glass available, such as Low-E 180, Low-E 272, and Low-E 366.

Internal mini-blinds

Internal mini-blinds are a classic tested by times. They are perfect to control the amount of light to let in during the day and ensure absolute privacy at any time. They are easy to operate and practically maintenance free.

grilles on sliding door


Make your doors special by adding unique decorative grille pattern. Decorative grilles can make an otherwise standard door look extraordinary and add a whole new dimension to your home appearance. Some home owners prefer the look of grilles in their doors to complement the architectural design and augment the look of their home. Interior grilles are installed between the glass units and require no maintenance, which leaves the door surface smooth for easy cleaning.


V-Groove glass offers an alternative to grilles adding a decorative option to personalize sliding patio doors. It adds a touch of luxury without compromising practicality and not impeding light. There are options of Prairie or Colonial V-Groove patterns.

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 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. While featuring a light construction and elegant design, the screens are sturdy with aluminium frame and fiberglass mesh and lock and provide protection allowing maximum air flow.

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 much more resistant to force. It is heat resistant and its thermo stability is twice that of the regular glass, meaning it can withstand higher temperatures. In addition, should the glass break, it does not separate into large and dangerous chards as the 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 the 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 resistance 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 with time. 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.

Nylon Rollers

Our nylon rollers make sliding patio door operation not louder than a whisper with smooth gliding.

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 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

While Low-E coating is not visible for most of its grades and lets most visible light through, 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.
