Sliding Doors Features

Vinyl Construction
Windowsville sliding patio doors are crafted from premium, 100% lead-free Canadian-made uPVC. This advanced material offers superior resistance to impact and discolouration, outperforming traditional options for long-term durability and appearance.
Easy-to-operate Screen
Our easy-to-operate sliding patio door screens are installed on the exterior side of the door for optimal protection against insects and the elements. Designed with a lightweight aluminum frame and durable fiberglass mesh, these lockable screens offer reliable security and excellent airflow, combining practicality with sleek, modern design.


Tempered Glass
Tempered glass, often referred to as safety glass, is 4 to 5 times stronger than standard annealed glass, making it highly impact-resistant. It offers superior heat resistance and double the thermal stability of regular glass. In the rare event of breakage, it shatters into small, blunt fragments instead of sharp shards, significantly reducing the risk of injury, especially for children.
Argon gas filling
The space inside the thermal glass unit of our sliding patio doors is filled with argon gas instead of air. Argon is an inert, odourless, and safe gas that’s denser than air, helping reduce heat transfer between panes and improving insulation performance. Combined with Low-E coating, it brings the glass temperature closer to room temperature and helps prevent condensation by reducing water vapour buildup.


Warm Edge Spacer
The non-metal structural foam spacer helps keep the glass unit firmly in place and improves energy efficiency. Our dual-seal system combines an adhesive sealant for structural integrity and a secondary sealant that resists moisture and vapour. Both sealants are highly durable, performing well under extreme temperatures, high humidity, and prolonged UV exposure.
Interior Finishes
Vinyl casings are an excellent way to enhance the look of your sliding patio door. Vinyl is a durable, low-maintenance material that won’t chip, fade, rot, or deteriorate over time. We use advanced technology and premium materials to ensure a flawless finish that retains its original colour. A range of rosette (trim corner) styles is also available to add a unique, decorative touch.


Nylon Rollers
Enjoy a whisper-quiet sliding experience with our precision-engineered nylon rollers. These smooth-gliding rollers allow for effortless operation, without any noise or disruption.
Double and triple-pane insulated thermal units
Our sliding patio doors are available with two or more layers of glass joined in a fully triple-sealed thermal unit. This advanced design creates an effective barrier against heat loss, humidity, and noise, ensuring maximum comfort and energy efficiency in your home.


Integrated brickmold
A brickmold is the exterior trim that frames your sliding patio door like a picture, filling the gap between the door and the surrounding surface, such as brick, siding, stucco, or stone. It adds a clean, finished look to the exterior. We offer a range of brickmold sizes and styles, many of which can be shaped to fit curved or custom openings.
Low-E Glazing Options
Low-E coating is nearly invisible and allows the majority of visible light to pass through, while providing year-round solar control and comfort. In warm weather, it blocks heat and harmful UV rays; in cold weather, it reflects indoor heat back into the room. Multiple Low-E coating levels are available to suit different performance needs and climates.

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!Â
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.
