When it comes to selecting windows for a new build or renovation project, the choices can feel overwhelming. Among the many options available, tilt and turn windows have steadily gained popularity across residential and commercial markets worldwide. Originally developed in Europe, these windows offer a practical blend of functionality, security, and clean aesthetics that suit a wide range of architectural styles. Whether you are an architect, contractor, or property developer, understanding what makes tilt and turn windows stand out can help you make a more informed decision for your next project.
A tilt and turn window operates in two distinct modes. By turning the handle 90 degrees, the window swings inward like a traditional casement, providing a wide opening for maximum ventilation and easy access for cleaning. By turning the handle 180 degrees, the top of the window tilts inward while the bottom remains secured — allowing fresh air to circulate without fully opening the sash. This dual-function design is what sets aluminium tilt and turn windows apart from conventional single-function windows.
The tilt position is especially useful during light rain or at night, when you want airflow without compromising security. The turn position makes these windows ideal for spaces where you need a full opening, such as kitchens, living rooms, and balconies.
Versatile Ventilation. The tilt function lets you control airflow precisely. You can keep the window tilted for gentle, draft-free ventilation even during inclement weather — something fixed or single-function windows cannot offer.
Enhanced Security. When in the tilt position, the window opening is too narrow for anyone to enter, yet still allows air exchange. High-quality models feature multi-point locking mechanisms around the entire perimeter of the sash, making forced entry significantly more difficult than with standard windows.
Easy Maintenance. Because the sash swings inward, you can clean both the interior and exterior glass surfaces from inside your home. There is no need for ladders or professional window cleaning services, particularly for upper-floor installations.
Space Efficiency. Unlike outward-opening casement windows that protrude into walkways or balconies, tilt and turn windows open inward, making them an excellent choice for buildings with limited exterior clearance.
Thermal Performance. Modern tilt and turn windows use multi-chamber thermal break profiles and high-quality insulation strips to achieve excellent energy efficiency. When properly sealed, they help maintain indoor temperatures and reduce heating and cooling costs throughout the year.
Not all windows are built to the same standard. When evaluating tilt and turn window manufacturers, there are several key factors to keep in mind:
ALPES, a professional system window and door manufacturer based in Guangdong, China, produces two standout tilt and turn window models designed for demanding residential and commercial applications.
AW90 Passive Window
The AW90 is engineered for superior thermal performance, achieving a K-value as low as 1.3 — meeting passive house standards. Its 90mm frame depth accommodates thick multi-chamber insulation strips and insulation sponge, while the 360-degree locking point distribution provides full-perimeter security. The AW90 features a dual-matrix eight-layer sealing system, including extended, composite, welded, threaded, and dense sealing strips. It comes standard with Winkhaus hardware — a German brand with 169 years of engineering heritage — and offers optional C-Slot ROTO hardware for additional flexibility. The window has passed 240-hour salt spray corrosion resistance testing and demonstrates 5,000N shear resistance strength.
AW113 Series
The AW113 series offers a versatile inward-opening tilt and turn solution with a 113mm frame width, suitable for a broad range of residential applications. Like all ALPES products, it uses 6060-T66 aluminum profiles and PA66GF25 insulation strips for consistent thermal performance. Both models are available in standard colors including Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee, with custom color matching available upon request.
ALPES operates from a 100,000-square-meter production base with two manufacturing centers in Foshan and Zhaoqing. This scale allows the company to serve projects across multiple regions, including the Middle East, Australia, and Southeast Asia. Past installations include luxury villa projects in Saudi Arabia, high-end residential developments in Dubai, and modern villa projects in Australia.
The company's commitment to quality is reflected in every detail: from the 6060-T66 grade aluminum profiles to the full glue-injection corner bonding process that creates seamless, monolithic frame structures. Hardware partnerships with ROTO, Winkhaus, CMECH, and Wehag ensure that every window operates smoothly and reliably for years. For specifiers and buyers looking for tilt and turn window suppliers who can deliver consistent quality at competitive factory-direct pricing, ALPES offers a compelling combination of manufacturing capability and product expertise.
