When designing a modern home or commercial building, every detail matters — and few elements have as much impact on comfort, energy efficiency, and aesthetics as the windows you choose. Among the many options available today, tilt and turn windows have emerged as a top choice for architects, builders, and homeowners who refuse to compromise on performance or style. Originating in Europe and now gaining traction worldwide, this dual-function window system combines intelligent engineering with everyday practicality in a way that traditional sliding or hung windows simply cannot match.
A tilt and turn window operates in two distinct modes with a single handle. Turn the handle 90 degrees, and the window swings inward like a casement, providing a wide opening for maximum ventilation and easy cleaning access. Turn the handle 180 degrees, and the top of the sash tilts inward, allowing fresh air to circulate while keeping rain out and maintaining security. This dual-action design is not just a clever convenience — it represents a fundamentally superior approach to window engineering, with multi-point locking hardware that seals the sash against the frame on all four sides.
As one of the leading tilt and turn window manufacturers based in China, ALPES brings decades of specialized experience to every product. Operating from a 100,000-square-meter manufacturing facility with two major production centers in Foshan and Zhaoqing, Guangdong, the company has built a reputation for delivering high-end system windows and doors that meet rigorous international building codes.
ALPES currently offers two standout models in the tilt and turn category. The AW90 Passive Window achieves a remarkable thermal K-value of just 1.3, making it suitable for passive house and ultra-low-energy projects. Its 360-degree locking point distribution, dual-matrix eight-layer sealing system, and 240-hour salt spray corrosion resistance rating set it apart in demanding climates. The AW113 Series extends the lineup with a wider 113mm frame profile, delivering enhanced structural rigidity for larger openings while maintaining the smooth tilt and turn operation that defines the category.
Key Performance Data — AW90 Passive Window: K-Value 1.3 | 6060-T66 Aluminum | 1.8mm Profile Thickness | Multi-Chamber Insulation Strip + Insulation Sponge | Winkhaus Hardware (169 Years German Engineering) | 5,000N Shear Resistance
The performance of aluminium tilt and turn windows begins with the raw materials. ALPES exclusively uses 6060-T66 grade aluminum profiles with thicknesses ranging from 1.8mm to 2.5mm, exceeding new national standards. Each profile incorporates PA66GF25 multi-chamber thermal break insulation strips, effectively eliminating thermal bridging and delivering the warm-in-winter, cool-in-summer comfort that modern buildings demand.
Hardware is equally critical. ALPES partners with Germany's most respected names — ROTO, Winkhaus, and Wehag — to equip every window with precision-engineered transmission boxes, anti-pry lock points, and high-load stainless steel hinges. The CMECH handles, winners of the German Red Dot Design Award, have been tested to 30,000 cycles. This is hardware built to perform flawlessly for decades.
While tilt and turn windows are a flagship offering, ALPES provides a comprehensive product range that includes casement windows, sliding windows, sliding doors, and sunrooms. This breadth allows project developers and contractors to source all aluminum fenestration products from a single reliable partner, simplifying procurement and ensuring consistent quality across the entire building envelope.
The company's global project experience spans luxury villas in Saudi Arabia, high-end residential projects in Dubai, and modern architectural installations in Australia. Each project benefits from ALPES's direct-from-factory pricing model, which eliminates intermediary markups while maintaining the exacting quality standards that international buyers expect.
Every building is unique, and ALPES treats every order accordingly. Standard color options include Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee, with custom color matching available for branded or architecturally specific palettes. Glass configurations range from standard insulated units to advanced options with inert gas filling, multiple tints, and specialized acoustic or solar control properties. Screen mesh options include standard 40# black stainless steel and high-definition anti-PM2.5 mesh for projects in urban or high-pollution environments.
