Benefits of Vinyl Windows

Vinyl windows have dominated the window market because of the many advantages they offer over other options, such as wood or aluminum framed windows. Technological advancements have created windows that perform well even in the harshest of Canadian climates. With Window Mart vinyl windows, you can enjoy a more comfortable home any time of year.

100% Lead-free uPVC
Window Mart windows are made from a 100% lead-free uPVC powder compound. Their unique construction gives them excellent resistance to impact, cracking, and discoloration.

Sealed Glass Unit
Window Mart windows feature a completely sealed glass unit with 13/16″ overall thickness. We offer multiple options for glazing and thickness depending on the model.

Fusion Welded Corners
Fusion welding creates a watertight and airtight window frame. Internal walls are also welded to improve overall strength and structural integrity.

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

Vinyl is a desirable material for window construction. Homeowners, builders, and sub-contractors prefer vinyl windows because of their outstanding thermal performance. Window Mart is committed to providing high-quality and energy-efficient window options. We use Low-E glass, warm-edge spacers, and vinyl window frame with a unique multi air chamber system to improve energy-efficiency for all our windows. Unlike aluminum or wood framed windows, vinyl windows significantly reduce heat loss and maintain a comfortable and consistent environment inside your house all year round.

The quality and energy-efficiency of vinyl windows can vary which is why it is important to choose ENERGY STAR Rated windows. The ENERGY STAR rating system guarantees a minimum standard for energy efficiency. All the windows available at Window Mart are ENERGY STAR Rated, so you can rest assured that you are investing in quality products.

Professional installation is also a major factor that contributes to the overall performance 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. Window Mart offers complete window installation services to ensure that your investment in new vinyl windows is handled properly.

Worth Reading: Understanding Energy Efficiency Ratings for Windows

Vinyl windows are the ideal window option because of how low maintenance they are. They do not require the same upkeep as other window frame options, as they are more durable and resistant to deterioration. Vinyl windows are also simple to clean, with as little as a gentle wipe down to remove any built-up dirt and grime.

Vinyl windows come in a wide variety of styles, configurations, and colors. Window Mart’s selection of vinyl windows include an array of distinctive, artistic touches from old-fashioned rosettes for interior trim all the way to wood-stain finishes for that truly elegant flair. With virtually endless options, vinyl windows can be flawlessly integrated into any aesthetic.

All Window Mart windows are manufactured using 100% lead-free uPVC (unplasticized polyvinyl chloride) powder compound, which provides exceptional resistance against moisture, fading, and impact. Our vinyl window frames are backed by a robust warranty package that guarantees they will not warp, crack, or blister. With vinyl window frames, your windows will boast outstanding performance and long-lasting beauty that stands up against the Canadian elements.

Unlike wood or fibreglass framed windows, vinyl windows are a cost-effective option for home renovations as well as new construction. They are an excellent investment as they require little to no maintenance and can greatly reduce home energy bills. Their durability also means that your investment will stand the test of time.
