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.
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.
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.
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

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
