A high-performance PVC-U tilt and turn window system offering contemporary styling, dual inward-opening functionality, and outstanding thermal, acoustic, and security performance for modern buildings.
Application
The Spectus Tilt & Turn Window is suitable for a wide range of architectural applications where dual-function operation, secure ventilation, and high thermal performance are essential. Its inward-opening design, slim sightlines, and robust PVC-U construction make it particularly well-suited to multi-storey buildings and environments requiring safe internal cleaning and flexible ventilation.
High-Rise Residential Developments
Ideal for apartment blocks, student accommodation, and multi-storey housing, the Spectus Tilt & Turn Window allows for safe internal cleaning and controlled ventilation. Its inward-opening sash supports easy maintenance from within the building, while its contemporary styling and thermal performance contribute to compliance with Building Regulations.
Care Homes and Assisted Living
In settings where occupant safety and ease of use are priorities, such as care homes and assisted living facilities, the tilt-before-turn functionality provides secure ventilation and intuitive operation. Optional restrictors and safety features help ensure safe use by vulnerable residents.
Urban and Mixed-Use Buildings
For city-centre developments, regeneration schemes, and mixed-use buildings, the Spectus Tilt & Turn Window offers a sleek, modern aesthetic. Its wide colour palette and compatibility with curtain walling systems allow it to integrate seamlessly into a variety of architectural designs.
Public Sector and Commercial Buildings
The system is also well-suited to schools, hospitals, offices, and other public buildings. Its durable PVC-U construction and low-maintenance design make it ideal for high-traffic environments, while its secure locking and thermal efficiency enhance building performance and occupant comfort.
Refurbishment and Retrofit Projects
With its clean lines, inward-opening functionality, and flexible sizing, the Spectus Tilt & Turn Window is an excellent choice for upgrading existing buildings. It can replace older timber, aluminium, or steel systems while significantly improving thermal efficiency, security, and aesthetics. It is also suitable for use in conservation areas (subject to planning approval), where a modern performance standard must be achieved without compromising visual integrity.
