Precision-Engineered Aluminum Windows and Doors, Built to Order
Our custom aluminum windows and doors are made-to-measure architectural glazing systems built around a thermally broken aluminum frame. Each unit is manufactured to your exact dimensions, configuration, color, and glazing specification, delivering the strength and slim profiles of aluminum with the energy efficiency required by Passive House standards and modern building codes.
Performance is backed by third-party certification across our manufacturing group. Our casement systems are NFRC certified for the North American market, our Passive House–certified aluminum frame achieves a whole-window U-value of 0.78 W/(m²K) — Passive House efficiency class phB for cool, temperate climates — and our insulating glass units are certified to the Australian standard AS 4666:2012. This makes our systems suitable for high-end residential projects, energy-efficient builds, and specification-driven architectural work across the U.S., Canada, and Europe.

Frequently Asked Questions
Are your aluminum windows Passive House certified?
Yes. Our aluminum window frame (XML-S96) is a Certified Passive House Component (PHI Component-ID 2557wi03), achieving a whole-window U-value of 0.78 W/(m²K) and Passive House efficiency class phB for cool, temperate climates.
What U-value can your windows achieve?
Our certified frame achieves a whole-window Uw of 0.78 W/(m²K) with 0.70 glazing. With higher-quality glazing (Ug 0.54), the window U-value improves to 0.68 W/(m²K). Installed U-value is 0.84 W/(m²K).
What certifications do your products have?
Our casement systems are NFRC certified (CPD HHT-M-1) for North America, our aluminum frame is a Certified Passive House Component (PHI ID 2557wi03), and our insulating glass units are certified to AS 4666:2012 (CSi Licence 7664). All certificates can be independently verified with the issuing bodies.
Can I customize the size, color, and glazing?
Yes. Every unit is made to order. You can specify custom dimensions, any RAL color, single or dual-color finishes, and glazing from double to triple (up to 56.7mm), including Low-E, laminated, acoustic, and solar-control options.
What is the thermal break made of?
Our frames use a low-lambda polyamide thermal break (0.21 W/mK) combined with Kooltherm (0.022 W/mK) and PE foam insulation, plus SWISSPACER Ultimate Pro warm-edge spacers — the combination that delivers Passive House–class performance.
Do you offer OEM or private-label manufacturing for distributors?
Yes. As a direct manufacturer, we offer OEM and private-label options, competitive wholesale pricing, and export support to the U.S., Canada, and Europe.
Do you provide CAD and BIM files for architects?
