Thermally Broken Aluminum Windows (Energy Star Certified)
Meeting today's strict North American building codes doesn't mean you have to sacrifice the sleek, modern aesthetics of metal frames. Designed for architects, builders, and developers, our thermally broken aluminum windows are fully Energy Star certified, delivering architectural-grade durability without the thermal transfer issues of traditional aluminum.
Whether you are spec'ing a high-end residential build in a cold climate or outfitting a commercial space, these windows provide the structural integrity of aluminum while dramatically lowering HVAC loads.

Why Spec Our Energy Star Aluminum Windows?
As one of the leading energy efficient aluminum window manufacturers in North America, we engineer our products to solve real-world construction challenges:
- Advanced Thermal Break Technology: We use reinforced polyamide struts to separate the interior and exterior aluminum profiles. This completely breaks the conductive thermal bridge, eliminating condensation and heat loss.
- NFRC Rated & Energy Star Compliant: Independently tested to meet stringent U-Factor and Solar Heat Gain Coefficient (SHGC) requirements, ensuring your projects qualify for local energy rebates and tax credits.
- Architectural Flexibility: Narrow sightlines maximize glass area and natural light. Available in standard and custom energy star aluminum windows for cold climates, ensuring a perfect fit for complex structural openings.
- Commercial-Grade Durability: Extruded from heavy-duty T6063-T5 aluminum alloy, these frames resist warping, corrosion, and structural fatigue, even under heavy wind loads.

FAQ
Q: Are these windows rated for Energy Star Northern climate zones?
A: Yes. By utilizing triple-pane glazing, high-performance Low-E coatings, and wide polyamide thermal struts, our windows achieve the U-Factors (≤ 0.22) required for the strictest Northern climate zones in the US and Canada.
Q: What exactly makes these frames "thermally broken"?
A: Standard aluminum conducts heat and cold easily. We insert a structural polyamide insulator (a poor conductor of heat) between the interior and exterior aluminum extrusions. This "break" stops the transfer of exterior temperatures to the interior, eliminating drafts and frame condensation.
Q: Do you offer custom sizing for large-scale commercial projects?
A: Absolutely. While we stock standard sizes to keep lead times short, we specialize in commercial grade energy star aluminum windows for home use and high-rise applications. We can manufacture to your exact architectural rough openings.
Q: Are your windows NFRC certified?
A: Yes. All of our Energy Star certified lines carry National Fenestration Rating Council (NFRC) labels, providing verified, third-party data on U-Factor, SHGC, and Visible Transmittance (VT) for your building inspectors.
Q: What is the standard lead time for bulk B2B orders?
A: Lead times vary based on customization and volume. Standard configurations generally ship within 4–6 weeks, while custom colors or oversized custom geometries typically require 8–10 weeks. We provide firm timelines during the quoting process.
Q: Can these windows help a project achieve LEED certification?
A: Yes. The energy efficiency (U-Factor/SHGC) contributes to energy performance points, while the recycled content of our aluminum and the longevity of the product can contribute to materials and resources credits.
Q: How does the warranty work for contractors and distributors?
A: We offer a B2B-focused warranty: 10 years on the aluminum finish (AAMA 2604 standard), 20 years on the insulated glass units (against seal failure), and 5 years on hardware. We work directly with our trade partners to expedite any replacement parts.
