When it comes to selecting windows for a modern residential or commercial project, the specification process can be overwhelming. With so many styles, materials, and manufacturers to choose from, finding the right balance between aesthetics, performance, and budget is a genuine challenge. Among the many options available, tilt and turn windows have emerged as a standout solution — offering a versatile dual-function design that combines exceptional ventilation control with superior security and energy efficiency.
For builders, architects, and property developers seeking high-quality tilt and turn windows for sale, sourcing directly from an experienced manufacturer can make all the difference. ALPES, a professional system window and door manufacturer based in China, delivers premium aluminum tilt and turn windows engineered to meet international building standards — at competitive factory-direct pricing.
Tilt and turn windows are a European-origin window system that offers two distinct opening modes from a single sash. In the "tilt" position, the top of the sash tilts inward by a few centimetres, allowing secure, controlled ventilation without fully opening the window. In the "turn" position, the window swings inward like a traditional casement window, providing maximum airflow and easy access for cleaning.
This dual-functionality makes tilt and turn windows an increasingly popular choice for high-rise apartments, luxury villas, and commercial buildings — particularly in markets where safety, energy performance, and modern aesthetics are top priorities.
Understanding the full benefits of tilt and turn windows helps explain why architects and developers continue to specify them for premium projects worldwide.
The tilt mode provides draft-free, secure ventilation — ideal for night-time cooling or rainy days when you want fresh air without letting water in. The turn mode offers full opening for maximum airflow and easy emergency egress.
When in the tilt position, the opening is too narrow for an intruder to enter. ALPES tilt and turn windows feature multi-point locking systems with hardware from German brands like Winkhaus and ROTO, ensuring full-perimeter security around the entire sash.
Thermal efficiency is at the core of modern window design. ALPES manufactures tilt and turn windows with multi-chamber thermal break systems using PA66GF25 insulation strips. The flagship AW90 Passive Window achieves a thermal K-value as low as 1.3, meeting the rigorous standards for passive house construction.
Because the sash opens inward, cleaning both the interior and exterior glass surfaces is effortless — a significant advantage for upper-floor installations where external cleaning is otherwise difficult or expensive.
Unlike outward-opening casement windows, tilt and turn windows do not protrude into external spaces. This makes them ideal for balconies, walkways, and densely built urban environments.
ALPES offers two distinct tilt and turn window series, designed to meet different performance requirements and budget considerations.
The AW90 is the flagship model in the ALPES tilt and turn lineup, engineered for projects where maximum thermal performance is non-negotiable.

The AW90 is ideal for passive house projects, luxury residences, and any application where energy performance is the defining specification.
The AW113 series offers a complementary option for projects that require the tilt and turn functionality with a different frame configuration. Engineered with the same 6060-T66 aluminum alloy and German hardware compatibility, the AW113 maintains the core quality standards that define the ALPES brand.
Both series are available in four standard color finishes — Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee — with custom color matching available upon request. Multiple insulated glass configurations are also offered to suit varying climate zones and acoustic requirements.
Selecting the right manufacturer for your tilt and turn windows is just as important as choosing the right window style. Here is what sets ALPES apart.
