When it comes to selecting windows for high-end residential or commercial projects, the decision goes far beyond aesthetics. Modern construction demands windows that deliver exceptional energy efficiency, security, and ease of use — all without compromising on design. This is where
tilt and turn windows have emerged as the preferred choice for architects, builders, and property developers around the world.
What Are Tilt and Turn Windows?
Tilt and turn windows are a European-engineered window system that offers two distinct opening modes from a single handle position. Turn the handle 90 degrees, and the window swings inward like a traditional casement window, providing full ventilation and easy access for cleaning. Turn the handle 180 degrees, and the window tilts inward from the top, allowing fresh air circulation while maintaining security and keeping rain out.
This dual-action mechanism is not just a convenient feature — it is an engineered system designed to deliver superior protection against air, water, and noise for decades of reliable service. For multi-story buildings, the inward-opening design is particularly advantageous, as it allows safe cleaning from inside the room without the need for external access.
Why Choose Aluminium Tilt and Turn Windows?
While tilt and turn windows are available in various materials,
aluminium tilt and turn windows offer distinct advantages that make them the top choice for luxury and performance-driven projects.
Superior Structural Strength — 6060-T66 grade aluminum profiles with thicknesses from 1.8mm to 2.5mm provide exceptional rigidity and resistance to deformation, even in large-format installations. This allows for expansive window openings that would be impractical with uPVC or wood frames.
Outstanding Thermal Performance — Multi-chamber thermal break systems with PA66GF25 insulation strips achieve K-values as low as 1.3 W/m²K, meeting the most demanding energy efficiency standards including Passive House requirements.
Slim Sightlines, Maximum Views — The inherent strength of aluminum allows for narrower frames and larger glass areas, maximizing natural light and panoramic views without sacrificing structural integrity.
Long-Lasting Durability — Powder-coated aluminum frames resist corrosion, fading, and weathering. With 240-hour salt spray corrosion resistance certification, these windows maintain their appearance and performance for decades, even in coastal environments.

Flagship Product: AW90 Passive Window
The AW90 Passive Window is the crown jewel of the ALPES tilt and turn range — a high-performance inward-opening system engineered to meet the stringent requirements of Passive House certification. This is not simply a window; it is a precision-engineered thermal barrier designed for projects where energy performance cannot be compromised.
AW90 Key Specifications:
Profile Grade: 6060-T66 aluminum, 1.8mm thickness meeting new national standards
Thermal K-Value: 1.3 W/m²K — among the lowest in its class
Insulation: Multi-chamber insulation strip with insulation sponge
Frame Wall Width: 90mm for robust structural performance
Hardware: Winkhaus (169 years of German engineering) with optional ROTO C-Slot configuration
Sealing System: Dual-Matrix Eight-Layer Sealing — incorporating extended, composite, welded, threaded, and dense sealing strips
Security: 360° locking points distribution for full-perimeter protection
Corrosion Resistance: 240-hour salt spray test certified
Shear Resistance: 5,000N strength rating
The AW90 features full injection adhesive bonding across the frame, mullion, glass sash, and screen — creating a seamless monolithic structure that eliminates weak points. The eight-layer sealing system ensures exceptional protection against wind-driven rain, dust infiltration, and external noise, making it suitable for the most demanding climates.
AW113 Series: Versatile Performance
For projects requiring a different frame configuration, the AW113 Series offers a 113mm frame width with the same premium 6060-T66 aluminum construction. It features CMECH hardware — a German Red Dot Design Award winner independently tested to 30,000 operating cycles — and a triple-sealing defense system that effectively blocks wind, rain, noise, and extreme temperatures.
What You Gain When You Source from ALPES
Choosing a dedicated
tilt and turn aluminum windows factory like ALPES means you are not just buying products — you are investing in a comprehensive manufacturing and supply partnership.
Custom Manufacturing — Every window is built to your exact specifications, including custom sizes, colors, glass configurations, and hardware options. There is no "standard size" limitation.
Premium German Hardware — ALPES partners exclusively with industry leaders: ROTO transmission boxes and anti-pry lock points, Winkhaus full hardware sets, CMECH award-winning handles, and Wehag premium hardware — all tested to tens of thousands of cycles.
Uncompromising Material Quality — Only 6060-T66 grade aluminum (not lower-grade alloys) and PA66GF25 multi-chamber insulation strips are used throughout the product range, meeting or exceeding the latest national standards.
Global Project Expertise — ALPES has successfully delivered luxury villa and commercial projects in Saudi Arabia, Dubai, Australia, and across the Middle East. This international experience means the team understands diverse building codes, climate conditions, and architectural preferences.
Factory-Direct Value — By manufacturing in-house at a 100,000 m² facility and selling directly, ALPES eliminates intermediary markups. You receive premium, German-hardware-equipped windows at competitive pricing that makes high-end specification accessible.
Color, Glass, and Finish Options

Custom color matching is available for projects requiring a specific palette.
Glass configurations include a range of insulated glass units with multiple tint and style options. For enhanced thermal performance, 27A super large insulating glass with inert gas filling is available on ｓｅｌｅｃｔ models, further reducing heat transfer and improving energy efficiency.
Ideal Applications
Tilt and turn windows from ALPES are engineered for a wide spectrum of project types:
Luxury residential villas and private residences
High-end apartment complexes and multi-family developments
Commercial office buildings and corporate headquarters
Hotels, resorts, and hospitality venues
Passive House and green building certified projects
Coastal properties and high-wind locations requiring superior weather resistance
The tilt function provides secure, weather-protected ventilation — ideal for bedrooms, bathrooms, and kitchens — while the full inward-swing mode allows for maximum airflow and effortless cleaning from inside the building. This makes tilt and turn windows particularly valuable for upper-floor installations where external access is limited or unsafe.
