Advanced Glass Technology for Canadian Comfort

 

At AlphaTech Windows, we use advanced glazing systems engineered specifically for the Canadian climate. Our high-performance LoE-180 and LoE-366 glass options deliver exceptional comfort, clarity, and efficiency—helping you save energy and maintain year-round comfort in your home.

Double-pane & Triple-pane glass

Every AlphaTech window is crafted using Cardinal Glass Industries’ latest Low-E coatings and our premium Super Spacer® technology, creating one of the clearest, most efficient window systems available today.

Glass Options

LoE-180 Glass – Cardinal CG + Simply Clean™

High Efficiency for Northern Climates

Key Benefits

  • Triple-glazed performance in a double-glazed format
  • Superior Low-E efficiency compared to standard coatings
  • Energy Star® rated (Zone C or greater)
  • Exceptional UV protection to prevent fading and damage
  • High solar heat gain for passive winter warmth
  • Includes Simply Clean™ ultra-smooth surface for easy maintenance
  • No haze, ensuring maximum clarity

Our energy-optimized design pairs LoE-180 glass coatings with our warm-edge Super Spacer® for enhanced performance. Choose from double or triple glazing with argon gas fill for maximum insulation.

In winter, LoE-180 captures heat energy from sunlight while reducing nighttime heat loss. In summer, it minimizes heat transfer from hot, humid outdoor air—resulting in lower heating and cooling costs year-round.

 

Designed for the Canadian Climate

LoE-180 improves the insulating value of your window by up to 40%, offering exceptional clarity, light transmission, and solar control. It’s the clearest, highest-performance glass solution for cold and mixed climates.

Glass Options

LoE-366 Glass – Cardinal CG

The Ultimate in Year-Round Performance

For homes seeking top-tier energy savings and comfort, LoE-366 glass delivers the perfect balance of solar control, visibility, and insulation. With three layers of silver coating, LoE-366 offers superior UV protection and temperature stability in any climate.

 

Key Benefits

  • Innovative triple-silver coating for ultimate efficiency
  • Blocks 95% of UV rays that cause fading and damage
  • Reflects 64% of unwanted solar heat
  • Retains 98% of indoor heating and cooling
  • Delivers the highest R-value for superior insulation
  • Crystal-clear appearance with no haze

Advantage LoE

Unlike standard Low-E products that block beneficial winter sunlight, LoE-366 allows free passive solar heat into your home while reflecting unwanted infrared heat in summer—delivering consistent comfort in every season.

Glass Options

HPE Glass (L8+)

Enhanced Triple-Pane Performance

Our HPE glass system combines multiple Low-E coatings in a triple-pane format for the highest possible energy efficiency. It features four layers of Low-E coatings—Cardinal LoE-366 on the exterior and LoE-180 on the interior—along with two gas-filled chambers (argon or krypton).

Available on all AlphaTech Platinum Series Windows, HPE glass provides:

 

  • Superior insulation and comfort
  • Increased condensation resistance
  • Compatibility with internal and external grills

Super Spacer® Technology

Superior Edge-Seal Performance

Every AlphaTech window is built using Super Spacer® Premium Enhanced technology—a non-metal, warm-edge spacer that delivers exceptional thermal efficiency and durability.

 

Key Advantages:

  • Low thermal conductivity for better insulation
  • Long-lasting edge-seal durability
  • Flexible foam matrix for structural stability
  • High desiccant content for moisture absorption
  • High-quality silicone sealant for strength
  • Excellent argon gas retention

Sound Reduction & Security

Quiet Comfort and Peace of Mind

By combining Super Spacer®, optimal air space, and SSP® (Sound & Security Performance) glass, AlphaTech windows achieve remarkable sound reduction—creating a quieter indoor environment.

 

  • Sound Reduction: Significant noise control through multi-layer design
  • Security: Outer SSP® glass layer increases strength and resistance—offering 10× the security of standard glass
  • Performance: LoE coatings combined with SSP® enhance overall U-value, R-value, and SHGC performance
