Premium Quality, Unbeatable Prices. Here’s How.

Alpha’s pricing reflects smart, efficient operations — not a race to the bottom. Every dollar you save comes from how we work, not what we build.

• Direct-to-Customer Model — We’re factory-direct. No distributors, no showroom markups, no sales commissions. The savings go straight to you.
• Lean Operations — Modern workflows and smart processes minimize waste. Efficiency at every step means you’re never paying for someone else’s overhead.
• Technology-Driven Accuracy — From precise measurements to optimized production, our technology eliminates errors before they become costly surprises.
• Focused Expert Team — We keep our team lean and skilled. Every person contributes directly to your windows, not to unnecessary administrative layers.

What you’re not paying for: exorbitant showroom rents, multi-layered sales commissions, or outdated manual processes.

The result? Exceptional windows backed by our 25-year warranty, at a price that reflects smart business practices — not compromised quality.

Vinyl Construction — Built to Last

Every Alpha window is manufactured from an exclusive, 100% lead-free uPVC powder compound — engineered for the Canadian climate, not just certified to meet it. This proprietary compound delivers superior resistance to impact and discoloration, so your windows hold their colour and structure through decades of freeze-thaw cycles and UV exposure. They will not crack, blister, or warp — and they require zero maintenance to stay that way.

• Impact-resistant uPVC — no dents, no rot, no painting
• Colour-stable through UV and extreme temperature cycles
• Will not crack, blister, or warp over time
• Completely maintenance-free for the lifetime of the window

Super Spacer® Technology — Advanced Glazing

Super Spacer® is the industry’s most durable insulating glass spacer system — included as standard in every Alpha window. It is a dual-seal insulating glass system: one material acts as a high-strength structural adhesive, the other as a dedicated moisture vapour barrier. Each does one job, and does it exceptionally well.

This 100% metal-free, structural foam spacer resists condensation, reduces energy costs, delivers long-life durability, and adds lasting comfort and value to your home.

• Optimized energy savings
• Enhanced comfort and health near windows
• Condensation and mold resistance
• Extreme durability for sustainable performance

The Glass That Separates a Quality Window from a Builder’s Basic

Most tract-built homes come with clear double-pane glass — functional, but that’s it. Low-E coatings are what make windows genuinely energy-efficient, year-round comfortable, and protective of your home’s interior. All Alpha windows use Cardinal LoE glass.

• LoE 180 — Warmth First (Best for cold climates)

  Designed for Canada’s cold winters. LoE 180 lets the sun’s warmth in during the day and keeps that heat inside at night. U-Factor: 0.26. Solar Heat Gain: 0.69. Best for north-facing windows or colder regions.

• LoE 272 — Year-Round Balance (Most popular)

  The go-to choice for most Canadian homes. LoE 272 delivers reliable cold-weather insulation while blocking enough summer heat to keep your cooling costs down. Reduces window heat gain by up to 50% compared to standard glass. U-Factor: 0.25. Solar Heat Gain: 0.41.

• LoE 366 — Ultimate Clarity & Control (Maximum solar protection)

  Three layers of coating give LoE 366 the best heat and UV protection available in a double-pane window. Blocks 95% of UV rays. Meets Energy Star requirements across all four Canadian climate zones. U-Factor: 0.24. Ideal for south- and west-facing windows.

• LoE i89 — The Efficiency Booster (Triple-pane performance, double-pane price)

  Added to the inner surface of the glass, LoE i89 works alongside any other LoE coating to dramatically improve heat retention. A double-pane window that performs close to a triple-pane at a fraction of the cost. U-Factor: 0.20 (with LoE 272). Scratch-resistant and virtually invisible.
