Premium Thermal Break Aluminium Casement Windows | Direct Manufacturer
Sourcing reliable fenestration products shouldn't be a bottleneck for your project timeline or your profit margins. As leading thermal break aluminium casement windows manufacturers, we engineer window systems designed specifically for commercial developers, custom home builders, and regional distributors.
Our casement profiles combine 6063-T5 structural grade aluminium with advanced polyamide thermal barriers to meet stringent 2026 energy codes, preventing heat transfer and eliminating condensation issues. Whether you are outfitting a residential development or a high-rise commercial space, our custom-fabricated units deliver on both performance and aesthetics.

Key Engineering Features
- Advanced Thermal Performance: Integrated 24mm to 35.3mm polyamide (PA66) thermal strips drastically reduce thermal bridging, bringing U-values down to passive-house standards.
- High-Security Hardware: Equipped with secure multi-point locking systems (compatible with German hardware like Siegenia or Hoppe) to meet commercial security testing standards.
- Glazing Flexibility: Fully compatible with double or triple glazed configurations, including Low-E and argon-filled cavities for superior acoustic insulation.
- Architectural Finishes: Available in 200+ RAL colors, including the highly demanded matte anthracite grey, as well as highly durable marine-grade powder coating and sublimation wood grain finishes.
- Weather Sealing: Automotive-grade EPDM triple-gasket sealing prevents water ingress and wind drafts, even in extreme coastal or high-altitude environments.

FAQ
Q: What is the average cost of aluminium casement windows per square metre for bulk orders?
A: Because we are a direct manufacturer, our wholesale cost of aluminium casement windows per square metre typically ranges from $120 to $250. This variance depends entirely on your chosen profile thickness, glazing specifications (double vs. triple), and custom hardware requirements. Contact our sales engineering team for an exact project quote.
Q: Do you manufacture triple glazed aluminium casement windows for cold climates?
A: Yes. Our thermal break profiles are extruded with wider glazing beads specifically designed to accommodate heavy-duty triple glazing (up to 44mm total glass thickness). This ensures maximum thermal efficiency and prevents winter condensation.
Q: What is your standard manufacturing lead time?
A: For standard colors (like white, black, or anthracite grey) and standard hardware configurations, our lead time is 20-25 days from drawing approval. Custom RAL powder coating or specialized architectural shapes require 30-35 days.
Q: Can these windows integrate with secure multi point locking systems?
A: Absolutely. Security is a baseline requirement for our commercial clients. All our operable casement sashes are pre-routed to accept heavy-duty, secure multi-point locking mechanisms, ensuring high-level intrusion resistance.
Q: How do you package the windows for international shipping?
A: We use export-grade packaging. Corners are protected with hard plastic casing, the frames are wrapped in shrink film to prevent scratching, and the entire unit is secured in fumigated wooden crates or steel pallets to guarantee zero damage during sea freight.
Q: Do you provide shop drawings before production begins?
A: Yes. Once a deposit is placed, our in-house CAD engineers provide detailed shop drawings (including cross-sections, opening directions, and node details) for your architect or site manager to sign off on prior to manufacturing.
Q: Are your profiles suitable for high-rise commercial applications?
A: Yes. We offer commercial-grade profiles (2.0mm wall thickness) that are structurally tested to withstand high wind loads (Class C5) making them highly suitable for mid-to-high-rise commercial developments.
