When selecting windows for a new build or renovation project, homeowners, architects, and contractors increasingly turn to a European innovation that has transformed the fenestration industry: tilt and turn windows. Unlike traditional casement or sliding windows, tilt and turn windows offer a dual-function opening mechanism that delivers superior ventilation, security, and ease of maintenance — all within a single, elegantly engineered frame.
A tilt and turn window operates in two distinct modes. Turn the handle 90 degrees, and the window swings inward like a casement window, allowing full access for cleaning and maximum airflow. Turn the handle 180 degrees, and the window tilts inward from the top, creating a narrow gap for secure, controlled ventilation. This dual-action design is what sets aluminium tilt and turn windows apart from conventional window types, and it is a key reason why they have become a staple in European architecture and are gaining rapid adoption in markets across the Middle East, Australia, and beyond.
The benefits of tilt and turn windows extend well beyond their dual opening mechanism. Here are the key advantages that make them a preferred choice for high-end residential and commercial projects.
The tilt function allows fresh air to enter from the top of the window while keeping the opening secure. This creates a gentle, draft-free airflow that is ideal for nighttime ventilation or for use during light rain, as the tilted sash naturally deflects water away from the interior.
In tilt mode, the window opening is too narrow for anyone to enter, yet the room remains ventilated. When fully closed, multi-point locking hardware distributed around the entire perimeter of the sash provides robust protection against forced entry.
Because the sash swings inward, both the interior and exterior glass surfaces can be cleaned safely from inside the building — a major advantage for upper-floor installations where external cleaning would otherwise require professional access equipment.
Unlike outward-opening casement windows that protrude into exterior spaces, tilt and turn windows operate entirely within the plane of the wall. This makes them ideal for balconies, terraces, and walkways where exterior clearance is limited.
Modern tilt and turn window systems are engineered with multi-chamber thermal break profiles and advanced sealing systems that deliver outstanding insulation against both heat transfer and outside noise.
At ALPES, we manufacture premium aluminum tilt and turn windows that combine European engineering principles with competitive direct-from-factory pricing. As a leading tilt and turn window manufacturers based in China, we operate two major production centers in Foshan and Zhaoqing, Guangdong, spanning a combined 100,000 square meters of manufacturing space.

The AW90 is our highest-performance tilt and turn window, designed to meet Passive House standards. Its Dual-Matrix Eight-Layer Sealing system — incorporating extended, composite, welded, threaded, and dense sealing strips — delivers exceptional air tightness, water resistance, and acoustic insulation. The 360° locking point distribution ensures full-perimeter security, while Winkhaus hardware brings 169 years of German precision engineering to every unit.
AW113 Series — Versatile Performance
The AW113 series offers a balanced combination of performance and value for projects that do not require Passive House-level certification. It shares the same 6060-T66 aluminum grade and rigorous manufacturing standards as the AW90, with a compact frame design that suits a wide range of architectural styles.
Color & Mesh Options
Both models are available in our standard color palette — Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee — with custom color matching available upon request. Screen mesh options include 40# black stainless steel mesh, 80# black/gray stainless steel mesh, and black high-definition anti-PM2.5 mesh.
With project experience spanning Saudi Arabia, Dubai, Australia, and the broader Middle East, ALPES understands the requirements of diverse climates and building codes. We manufacture to international standards, and our factory-direct model eliminates intermediary markups, giving you premium quality at competitive prices.
Every ALPES window uses 6060-T66 grade aluminum profiles with thicknesses from 1.8mm to 2.5mm, exceeding new national standards. Our PA66GF25 insulation strips ensure long-term thermal stability, and our hardware partners — ROTO, Winkhaus, CMECH, and Wehag — are among the most respected names in the industry.
From frame color and glass configuration to hardware selection and mesh type, every ALPES tilt and turn window is built to your exact specifications. Whether you need a single custom unit or a bulk order for a multi-unit development, our production lines are equipped to deliver.
Each window undergoes thorough quality checks throughout the manufacturing process. Our full glue-injection process, integrated corner brackets, and seamless welded corner seals ensure structural integrity and long-term durability. The AW90 has passed a 240-hour salt spray corrosion resistance test and achieves 5,000N shear resistance strength.
