Certificate type
A flush aluminium tilt & turn window offering dual-function operation, slim sightlines, top-tier thermal performance, and secure ventilation—ideal for high-rise and modern architectural projects.
Application
The Stellar Flush Aluminium Tilt & Turn Window is designed for use in a wide range of architectural settings where performance, aesthetics, and functionality are equally important. Its dual-function operation, true flush design, and high thermal efficiency make it an ideal solution for both new-build and refurbishment projects across residential, commercial, and public sector developments.
High-Rise and Medium-Rise Residential Buildings
This aluminium tilt & turn window is particularly well-suited to apartment blocks and mixed-use developments where ease of maintenance, secure ventilation, and modern styling are essential. The inward-opening turn function allows for safe and convenient cleaning of external glass from inside the building—an important feature for high-rise applications. The tilt function provides secure, controlled ventilation, making it ideal for urban living environments.
Contemporary Housing and Urban Regeneration
In low- to mid-rise residential schemes, the Stellar Flush Aluminium Tilt & Turn Window offers a clean, minimalist aesthetic that complements modern architectural styles. Its slim sightlines and flush finish enhance the visual appeal of façades, while its thermal performance supports compliance with energy efficiency targets. The system is also suitable for use in regeneration projects where modern performance must be balanced with design sensitivity.
Commercial and Mixed-Use Developments
For commercial buildings such as offices, hotels, and retail units, this aluminium tilt & turn window provides a professional, high-specification solution. Its robust aluminium construction ensures long-term durability, while its flush design and wide colour range allow for seamless integration into contemporary façades. The system’s security credentials, including PAS 24 and Secured by Design compliance, make it suitable for high-traffic environments.
Education and Public Sector Buildings
The Stellar Flush Aluminium Tilt & Turn Window is also ideal for schools, universities, healthcare facilities, and other public buildings. Its dual-function operation supports safe ventilation and ease of cleaning, while its thermal and acoustic insulation properties contribute to comfortable, energy-efficient internal environments. Optional restrictors and intelligent gearing enhance safety in settings where user control must be limited.
Refurbishment and Retrofit Projects
Thanks to its clean lines, flush finish, and flexible sizing, this aluminium tilt & turn window is an excellent choice for refurbishment schemes. It can be used to replace outdated systems while improving thermal performance, security, and aesthetics. The system’s ability to achieve U-values as low as 1.0 W/m²K makes it ideal for upgrading existing buildings to meet modern energy standards.
