ENERGY STAR Rated Vinyl Windows Made in Canada

Window Mart custom windows are constructed with a 100% lead-free uPVC powder compound — one of the most durable window materials available. Unlike aluminum windows, our aluminum clad vinyl windows combine the strength of aluminum cladding with the thermal performance of vinyl. This unique mixture makes every high performance window exceptionally resistant to impact and discolouration. You can rest assured that your investment will stand the test of time.

Why Vinyl Windows?

Vinyl has become one of the most popular window materials because of its unique blend of style, performance, and convenience. Boasting exceptional quality and outstanding energy-efficiency, vinyl windows deliver a great return on investment for any house. As a trusted dealer of vinyl windows and doors across Canada, Window Mart offers a wide range of window types — from casement and awning to slider and hung.

All feature a unique multi-chamber construction that maximizes insulation, thermal efficiency, and sturdiness. With extensive customization options, our windows for house projects — new builds or renovations — will complement any home perfectly.

FAQs

Vinyl windows are made from high-performance uPVC (unplasticized polyvinyl chloride). This material provides excellent thermal insulation, are non-biodegradable, resists warping and moisture, and requires minimal maintenance compared to wood or aluminum. That’s why they’re ideal for Canadian climates with harsh winters and hot summers.

Quality vinyl windows use multi-chamber frames, Low-E glass, argon gas, and tight seals to reduce heat transfer. These features keep heat inside in winter and outside in summer, which will lower your utility bills and improve comfort year-round. Window Mart products are ENERGY STAR® rated for Canada.

Our high-quality vinyl windows typically last 30–40 years with proper installation and care. Lower-end products may age faster, especially under extreme weather conditions, which is why material and installation quality matter.

We offer strong warranty protection, including:

  • 25-years on all vinyl components
  • 25-years on sealed glass units
  • 25-years on all hardware
  • 25-years on labour and materials

Our warranties are fully transferable, and non-prorated Adding value for owners and future buyers.

Double-pane windows are standard and energy efficient. Triple-pane adds a third layer of glass and an extra argon chamber, boosting insulation and reducing noise transfer— a good choice for colder climates like Alberta and Saskatchewan if you want maximum performance.

Replacing a single window can improve comfort locally, upgrading all old, drafty windows often maximizes energy savings and ensures uniform performance and appearance. Our experts can walk you through the best approach for your home.

Light condensation inside your home is normal in very cold weather. Persistent condensation between panes or continuous moisture can indicate poor insulation or failing seals. This can cause major problems — something we evaluate during your free consultation.

This is a common myth based on older technologies. Modern high-quality vinyl windows, like the ones sold by Window Mart, are engineered specifically for the Canadian climate. We use uPVC (unplasticized polyvinyl chloride), which is significantly more rigid and durable than standard plastic. It is fortified with stabilizers to resist impact even at -40°C and UV inhibitors to prevent warping or discoloration during hot summer days. In short: they are built to flex slightly with thermal expansion without losing structural integrity.

Absolutely. Canada has clear energy zones, and our windows meet or exceed the Energy Star requirements for the coldest zones (Zone 3), covering Alberta, BC, Saskatchewan, and Ontario. By installing our Triple Pane vinyl windows with Low-E coating and Argon gas, you ensure maximum heat retention, which may also qualify you for local government rebates and energy loans.

Not with Window Mart. We use premium-grade virgin-grade vinyl powder compounds containing high concentrations of Titanium Dioxide (TiO2). This acts as a powerful sunscreen for your windows, protecting the white finish from harmful UV rays. We stand behind this with our comprehensive warranty against discoloration.
