Vinyl vs. Aluminum Windows

/in /by

Quick Answer

For most Metro Vancouver homes, vinyl windows are the better choice. They achieve U-factors as low as 0.17 W/m²K, qualify for CleanBC rebates of up to $9,500, last 30–50 years with minimal maintenance, and perform well in Vancouver’s 192-day annual rainfall climate without corrosion risk. Aluminum windows are better suited to large-format contemporary applications, folding glass walls, and floor-to-ceiling glazing where slim profiles are architecturally required and a higher budget is available.

For Metro Vancouver homeowners, the vinyl vs aluminum decision has a local context most comparison guides ignore: 192 annual rainy days, salt-air exposure on the North Shore and coastal areas, and BC’s Energy Step Code requirements that set minimum window performance thresholds. This guide compares both materials specifically for BC conditions. For rebate eligibility for either material, see our BC window rebate guide .

Windows not only enhance the appearance of a home but also play a significant role in comfort and energy savings. This guide provides a detailed comparison to help you make an informed decision for your Vancouver home.

Key Takeaways

  • Vinyl windows last 30–50 years in Metro Vancouver’s climate; aluminum typically lasts 20–30 years.
  • Vinyltek’s Boréal Plus casement achieves a U-factor of ≤0.17 W/m²K, among the highest energy ratings from any Canadian vinyl manufacturer.
  • Both materials can qualify for CleanBC rebates of up to $9,500 with ENERGY STAR Most Efficient certification.
  • Vinyl is non-corrosive, with no salt-air degradation in coastal Metro Vancouver neighbourhoods such as White Rock, West Vancouver, and the Richmond waterfront.
  • Aluminum is better for floor-to-ceiling glass, with profiles 40–60% slimmer than vinyl, making it ideal for folding glass walls and large contemporary glazing.
  • Vinyl windows are manufactured locally in Delta, BC since 1986, with no overseas shipping delays or import markups.

What Are Vinyl Windows?

Vinyl windows are made from polyvinyl chloride (PVC), a highly durable and versatile plastic. Vinyltek uses 100% virgin uPVC from P.H. Tech’s exclusive UV-stabilized compound , which is more resistant to discolouration, impact, and warping than standard or recycled PVC. Our frames are used in products like our Boréal Casement & Awning Windows and EuroTwist Tilt-and-Turn Windows .

What Are Aluminum Windows?

Aluminum windows are favored for their slim profiles and larger glass areas. They are less effective as insulators without thermal breaks. Vinyltek’s Cortizo European aluminum door systems use polyamide thermal breaks suitable for floor-to-ceiling applications where slim profiles are architecturally required.

Durability

Vinyl Windows

Vinyl windows resist moisture, UV rays, and extreme temperatures; they will not warp, crack, or corrode. In Metro Vancouver’s coastal climate, this matters: homes in West Vancouver, Richmond waterfront, and White Rock experience salt-air exposure that corrodes uncoated metals. Vinyl is entirely non-reactive to salt air. See how long Vinyltek vinyl windows last in Vancouver for a full lifespan comparison.

Aluminum Windows

Aluminum windows are strong and durable. Aluminum conducts heat and can be prone to condensation. Untreated aluminum corrodes in coastal salt-air environments without protective powder coating. Modern aluminum windows incorporate thermal breaks to improve insulation properties.

Maintenance

Vinyl Windows

Vinyl windows require minimal maintenance: soap and water twice yearly. No painting, sealing, or coating inspection is needed. For step-by-step maintenance guidance, see our guide to maintaining vinyl windows for longevity .

Aluminum Windows

While generally low-maintenance, aluminum windows require periodic inspection of protective coatings, especially in coastal Metro Vancouver. Any scratches exposing bare aluminum should be addressed promptly to prevent corrosion.

Energy Efficiency and Insulation

Vinyl Windows

Vinyltek’s multichamber uPVC design amplifies vinyl’s natural insulating properties. Our Boréal Plus casement achieves U-factors as low as 0.17 W/m²K, among the highest from any Canadian vinyl manufacturer. All Vinyltek windows hold ENERGY STAR Most Efficient certification , the highest tier from Natural Resources Canada. Learn more about what makes a window energy-efficient for Vancouver homes .

Aluminum Windows

Aluminum has higher thermal conductivity than vinyl. Premium thermally-broken aluminum systems can achieve comparable U-factors, typically at 50–100% higher cost. For large-format applications, Vinyltek’s Cortizo folding glass door systems incorporate polyamide thermal breaks.

Design Flexibility and Aesthetics

Vinyl Windows

Vinyltek’s vinyl windows are available in a wide range of colours and finishes. For heritage homes, our DoubleNature simulated wood-look series provides a wood appearance with vinyl performance, popular for Fort Langley, Steveston, and Oak Bay renovations.

Aluminum Windows

Aluminum’s structural strength allows profiles 40–60% slimmer than vinyl, enabling larger unobstructed glass areas—a growing preference in West Vancouver and Whistler luxury builds.

Environmental Impact

Vinyl Windows

Vinyl windows are recyclable at end of life. Vinyltek manufactures locally on Annacis Island in Delta, BC, eliminating overseas shipping emissions. See our sustainability initiatives page .

Aluminum

Aluminum is highly recyclable; recycled aluminum requires only 5% of the energy of primary production. However, primary aluminum production is energy-intensive.
