Aluminum Casement Window Guide: How to Select the Right Type for Hotel Project?

🏗️ Project Experience:

We don’t just supply windows; we engineer solutions for complex environments. For instance, in the Hurtle & Co. apartment project in Adelaide, Australia, and the prestigious Banana Island Foreshore luxury residential area in Lagos, Nigeria, the developers faced a dual challenge: high acoustic requirements due to urban noise and extreme weather durability.

In both cases, we deployed our aluminium casement window system A80T. This solution balanced the need for modern, slim sightlines with the robust structural integrity required to withstand coastal winds and urban clamor.

To understand the broader landscape of window types and how they fit into architectural designs, you might want to read about the Types of Aluminium Windows: Styles and Features.

Modern projects typically require thermally broken aluminium casement windows. This involves a polyamide strip separating the interior and exterior aluminium profiles, significantly reducing heat transfer.

• Chamber Design: High-end systems utilize multi-chamber designs (isobaric chambers) to facilitate drainage and improve sound insulation.
• Finish: For projects near the coast (like our Banana Island case), surface treatment is crucial.

(To decide between finishes, refer to our guide on Anodizing vs. Powder Coating.)

The glass makes up 80% of the window’s surface area.

• Double glazed aluminium casement windows: The standard for modern construction, typically featuring a 12mm to 20mm argon-filled gap.
• Triple Glazing: Used in extreme climates for ultra-low U-values.
• Low-E Coatings: Essential for reducing solar heat gain in hotels and offices.

The durability of commercial aluminium casement windows depends heavily on the hardware.

• Dobradiças: Heavy-duty friction stays are required for large sashes.
• Handles & Locks: Multi-point locking mushrooms ensure the sash pulls tightly against the frame for security and sealing.

A sophisticated hidden drainage system is often employed in the A80T system, where water is channeled out through the sub-frame, preventing backflow during storms. EPDM gaskets are used for their longevity and resistance to UV degradation.

✅ Performance Standards

We believe in data-driven engineering. Our A80T series (covering both casement and tilt and turn aluminium windows) has undergone rigorous testing under the North American Fenestration Standard (NAFS).

• Design Pressure: Tested at approximately 1920 Pa for a 1200×1800 mm sample.
• Water Tightness: Achieved approximately 290 Pa, ensuring zero leakage even under heavy storm conditions.
• Thermal Performance: With double Low-E glazing, the whole window U-value is approximately 1.6 W/m²·K.
• Certifications: We hold NFRC certified aluminium windows status and multiple international standard certificates.

• Ventilação superior: The sash acts as a funnel, catching passing breezes and directing them indoors—perfect for aluminium casement windows for hotels in resort locations.
• Unmatched Sealing: The harder the wind blows, the tighter the sash presses against the frame.
• Security: Hook-shaped locks embedded in the frame make them extremely difficult to pry open.
• Aesthetics: Slim sightlines offer a modern, unobstructed view.

• Space Constraints: Outward opening sashes can obstruct walkways or balconies.
• Size Limits: The weight of the glass puts stress on hinges, limiting the maximum width compared to sliding systems.
• Custo: Generally, aluminium casement window prices per square meter are higher than sliding windows due to complex hardware and profiles.

Inward Opening Aluminium Casement Window

Common in Europe and high-rise buildings where exterior cleaning is dangerous. They require clear space inside the room to operate.

Outward Opening Aluminium Casement Window

The standard in the UK, USA, and Australia. They are excellent for waterproofing as the sash overlap prevents rain ingress.

🔄 Tilt and Turn Aluminium Windows

A hybrid engineering marvel. The tilt and turn aluminium window can swing inward like a door or tilt the top of the sash into the room for ventilation. This combines security with airflow.

For skyscrapers, we often see aluminium casement window details for curtain wall applications. These are “floating” sashes inserted into the grid of the glass facade, providing natural ventilation without disrupting the building’s sleek exterior skin.

For more on this system, see our guide on Curtain Wall Parts: The Complete Components Guide.

🏗️ Project Experience:

The Banana Island Foreshore project was a masterclass in location-based specification. The owners desired floor-to-ceiling glass. However, the coastal location meant salt spray was a constant threat.

We supplied the A80T system with a marine-grade PVDF coating and stainless steel 316 friction stays. This setup ensured that the aluminium casement windows vs upvc windows debate was settled: only aluminium could provide the structural strength for such large openings while resisting the corrosive environment.

Do you need NAFS rated aluminium windows for hurricane zones? Or energy efficient aluminium casement windows for cold climates? The A80T is versatile, but the glass spec must change accordingly.

While initial aluminium casement window prices per square meter might be higher than vinyl, the longevity of aluminium reduces replacement costs.

How does the window connect to the wall? Aluminium casement window installation details must be compatible with the external cladding. Poor waterproofing at the sub-sill is a leading cause of project failure.

🤝 Project Signals:

In many overseas bids, we actively assist the design team in writing the technical specifications. We ensure that critical parameters like U-values and aluminium casement window details for curtain wall integration are explicitly stated.

For the A80T system, we provide developers with a full technical dossier, allowing them to benchmark other suppliers against our NAFS rated aluminium windows. This transparency eliminates “apples to oranges” comparisons during procurement.

• Ignoring Maintenance Access: Designing fixed windows next to outward opening aluminium casement windows on high floors without a cleaning strategy.
• Hardware Overload: Exceeding the max weight of friction stays. Always check aluminium casement window sizes and dimensions against hardware charts.
• Thermal Bridging: Using non-thermally broken frames in cold climates, leading to condensation.
• Leakage at Miter Joints: Ensure corners are crimped and glued with high-quality sealant.

✅ Transparent Quality Assurance

For peace of mind, we have made our Quality Assurance data transparent. You can visit our product pages to view the NFRC energy labels, NAFS test reports, and ISO certifications for the A80T series.

Each project we undertake is backed by a dedicated technical team—from the initial aluminium casement window specification for projects to the final site acceptance.

If you are currently planning a residential complex, hotel, or office tower, we invite you to share this guide with your procurement and design teams.

1. Can I mix casement and sliding windows in the same project?

Yes. It is common to use aluminium casement windows for bedrooms (for seal and soundproofing) and sliding doors for balconies (for space-saving).

2. What is the best opening restrictor for hotel rooms?

We recommend concealed restrictor arms that limit the opening to 100mm. This meets safety codes for aluminium casement windows for high rise buildings while allowing ventilation.

3. Are thermally broken aluminium casement windows necessary for all climates?

Not necessarily, but highly recommended. In hot climates, they stop heat entering; in cold climates, they stop heat escaping. They are essential for achieving low U-values and are often required by code.

4. How do I maintain the hardware?

Clean the tracks and lubricate the hinges annually. For a detailed guide, see How to Clean Aluminium Window Frames.

5. What are the standard aluminium casement window sizes and dimensions?

While we specialize in custom fabrication, standard widths range from 600mm to 900mm, and heights up to 1500mm (or higher with heavy-duty hinges).
