Benefits of Window Mart Window Frame

Multi-chamber window frame

Window Mart Windows are made from 100% lead-free uPVC powder compound. It makes our windows more resistant to impact, cracking and discoloration.

Our windows have the highest number of internal air chambers, giving them outstanding insulation and sound abatement qualities, as well as maximizing thermal & energy efficiency.

Fusion welding corners have very attractive appearance and also eliminate any need for adhesive and sealants. Fusion welding creates perfect joints making a window frame completely watertight and airtight. Internal walls are also welded to improve an overall structural strength.

Why Vinyl Windows?

Vinyl has become one of the most popular window frame material for its unique blend of style, high-performance and convenience. High-quality and energy-efficient vinyl windows deliver great return of investment through energy saving, as well as through being a low maintenance product. Vinyl windows will serve you for many years without the need to be repaired or refinished.

Energy-efficient Vinyl Windows

Energy Efficient

Vinyl windows is a desirable material for homeowners, builders and sub-contractors because of their outstanding thermal performance. Window Mart pays a lot of attention to energy-efficiency in vinyl windows. We use Low-E glass, warm-edge spacers and window frame with unique air multi-chamber system to improve energy-efficiency of our windows.

Unlike aluminum windows – which conducts heat rapidly – vinyl windows do a better job at reducing heat loss and maintaining a comfortable environment inside a house all year round.

The quality and energy-efficiency of vinyl windows can vary. It depends on various factors, such as manufacturing, glazing, frame material, insulation, and many others. Always look for the ENERGY STAR symbol to make sure that you’re getting energy-efficient windows. You can also compare key metrics, such as U-factor, solar heat gain coefficient (SHGC) and energy rating.

2022 ENERGY STAR® Standards

Windows are eligible for ENERGY STAR® based on their U-factor that measures their overall heat loss, or, their Energy Rating (ER) that combines their passive solar heat gain (SHGC) through the glass with their overall heat loss and air leakage. Models must have a U-factor of 1.22 W/m2 or lower, or, an ER of 34 or higher.

Caution is advised when selecting windows and sliding glass doors with passive solar heat gain (SHGC) values above 0.45 that will face south or west, especially if there is more glass area than exterior wall area (high window to wall ratio), as this could cause uncomfortably warm room temperatures and higher cooling costs.

Professional installation is a major factor in determining the performance and ROI of the vinyl windows. If air is allowed to pass around the frame, then even the most energy-efficient and high-quality vinyl windows will lead to problems.

Low Maintenance Vinyl Windows

Low Maintenance

Vinyl windows are so popular due to the fact that they are low maintenance. Basically all you need to do is dust or clean them on occasion with a gentle detergent. On the other hand wood frames require a lot of upkeep due to rotting, splintering and fading.

You will find yourself constantly repainting, treating and repairing widows with wooden or metal farms. Vinyl windows are weather resistant so they can survive the elements without needing constant upkeep and repairs.

Durable Windows


All Window Mart windows are manufactured from 100% lead-free uPVC (unplasticized polyvinyl chloride) powder compound. This gives our windows strong resistance against moisture, fading, and impact as well as environmental sustainability.

uPVC window frame ensures that a window will not warp, crack, or blister.

Your windows will perform and look like new for years, even with such a changing Canadian climate.
