When it comes to choosing windows for a new build or renovation project, homeowners and builders face a sea of options. Casement windows, sliding windows, double-hung — the list goes on. But among all these choices, one style has been steadily gaining traction across Europe, the Middle East, and beyond:
tilt and turn windows. These dual-function windows offer a unique combination of ventilation control, security, and ease of maintenance that traditional window styles simply cannot match. In this guide, we will explore what makes tilt and turn windows a standout choice, and introduce you to ALPES — a leading China-based manufacturer delivering premium aluminum tilt and turn window systems to projects worldwide.
What Are Tilt and Turn Windows?
A tilt and turn window operates in two distinct modes. In the tilt position, the top of the sash tilts inward by a few inches, allowing fresh air to circulate while keeping the window securely locked at the bottom. This is ideal for gentle ventilation, even during light rain. In the turn position, the entire sash swings inward like a door, providing a wide opening for maximum airflow, easy cleaning from inside the home, and emergency egress.
This dual-functionality makes tilt and turn windows particularly popular in European architecture, and they are now increasingly specified in luxury residential and commercial projects across the Middle East, Australia, and other global markets.
The advantages of tilt and turn windows go far beyond their dual-opening mechanism. Here are some of the most compelling reasons builders and homeowners are making the switch:
- Superior Ventilation Control: The tilt function allows for secure, draft-free airflow without fully opening the window — perfect for night-time ventilation or during light weather conditions.
- Enhanced Security: When tilted, the window opening is too narrow for anyone to enter, and the multi-point locking system keeps the sash firmly in place. It is a built-in security feature that requires no additional hardware.
- Easy Maintenance: Because the sash swings fully inward, both the interior and exterior glass surfaces can be cleaned from inside the home — no ladders, scaffolding, or professional cleaning services required.
- Space Efficiency: Unlike outward-opening casement windows, tilt and turn windows do not protrude outside, making them a smart choice for walkways, patios, balconies, and upper-floor installations.
- Excellent Thermal Performance: When equipped with thermal break aluminum frames and multi-chamber insulation strips, these windows can achieve remarkably low U-values, helping to reduce heating and cooling costs year-round.
ALPES Tilt and Turn Window Systems
ALPES offers two advanced tilt and turn window systems, each engineered with precision to meet the demands of modern construction. Both models are built with 6060-T66 grade aluminum profiles, PA66GF25 nylon insulation strips, and hardware from Germany's most respected brands.
AW90 Passive Window
This is the flagship of the ALPES tilt and turn lineup. With a thermal K-value as low as 1.3, the AW90 is designed to meet passive house standards. It features a 90mm frame and glass sash depth, 1.8mm wall thickness, and multi-chamber insulation strips filled with insulation sponge for maximum thermal resistance.
The AW90 employs a dual-matrix eight-layer sealing system — including extended, composite, welded, threaded, and dense sealing strips — to deliver outstanding airtightness and water resistance. Hardware comes from Winkhaus, a German brand with 169 years of engineering heritage, and the system includes 360-degree locking point distribution for full-perimeter security.
For projects requiring insect protection,
tilt and turn windows with screens are available, with options including 40# black stainless steel mesh and high-definition anti-PM2.5 mesh. The system has also passed a 240-hour salt spray corrosion resistance test and a 5,000N shear resistance strength test.
AW113 Series
This model offers a 113mm frame width and 57mm glass sash thickness, with a full glue-injection process using integrated corner brackets that create a seamless monolithic structure. The multi-chamber design provides excellent warm-in-winter and cool-in-summer insulation.
The AW113 features triple sealing defense against wind, rain, noise, and extreme temperatures. Its hardware is supplied by CMECH, a winner of the German Red Dot Design Award, with all components tested to 30,000 cycles for long-term durability. The glass centerline, thermal break strip, and equal-pressure sealing strip are aligned on the same axis for optimal performance.
Both models are available in four standard color options — Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee — with custom color matching available to suit any architectural design. Various insulated glass configurations with multiple tint and style options can be specified to meet project requirements.
