How aluminium joists support various terrace surfaces
Aluminium joists are a crucial component in creating versatile and durable terrace surfaces. The Raaft® Terrace System utilises 30mm and 50mm Aluminium substructure Preventa® joists to provide a robust foundation for a variety of terrace surfaces.
These joists offer numerous benefits and support options for different materials, making them an ideal choice for modern terrace construction.
Aluminium joists versatility in surface options
Decking support
Aluminium joists excel in supporting various decking materials. The Raaft® system includes fire, wind, and slip-resistant extruded porcelain decking boards available in multiple colours.
These joists provide a stable base for installing these durable and aesthetically pleasing decking options.
Paving solutions
In addition to decking, aluminium joists are perfect for supporting paving materials. The Atria® Porcelain Tiles, part of the Raaft® system, can be easily installed on these joists, offering a wide range of styles, colours, and finishes for terrace surfaces.
Aluminium decking support
Aluminium joists are particularly effective for supporting aluminium decking materials. The Raaft® system allows for the installation of fire-resistant and slip-resistant aluminium decking boards, which are available in various colours and finishes.
These joists create a stable base that enhances the performance and appearance of the decking. Key advantages of aluminium joists

Fire safety
Aluminium joists contribute to the overall fire safety of terrace structures. The Preventa® joists are part of a Class A Fire-Rated modular terrace system, ensuring compliance with stringent safety standards.
Adjustability and levelling
Terrace surfaces often need to be built on uneven roofs or grounds. Aluminium joists, when used in conjunction with height-adjustable steel pedestals, allow for easy levelling and create a sturdy, safe terraced area regardless of the underlying surface conditions.
Lightweight yet strong
The use of aluminium for joists provides an excellent strength-to-weight ratio. This characteristic makes the joists easy to handle during installation while still offering robust support for various terrace surfaces.
Aluminium joists integration with modular systems
The aluminium joists in the Raaft® Terrace System are designed to seamlessly integrate with other components, creating a comprehensive and versatile modular solution for terrace construction. This integration offers several key advantages:
Customisable configurations
The modular nature of the system allows for endless design possibilities. Aluminium joists can be easily combined with height-adjustable steel pedestals to create level surfaces on uneven roofs or grounds.
This flexibility enables architects and designers to overcome common challenges in terrace construction, such as varying build heights and complex layouts
Compatibility with multiple surfaces
Aluminium joists in the Raaft® system are engineered to work with various surface options:
- Atria® Porcelain Tiles
- Aluminium decking boards
- Other compatible decking materials
This versatility allows for creative freedom in terrace design, accommodating different aesthetic preferences and functional requirements.
Easy installation and maintenance
The modular system, centred around aluminium joists, is designed for simple and fast installation with minimal fixings required. The system allows for easy access to services underneath:
- With aluminium decking, boards can be easily lifted and replaced using the Raaft® key
- Atria® tiles can be loose-laid or clipped onto the joists, allowing for individual tile removal when needed
Non-combustible solution
The integration of aluminium joists with other components in the Raaft® system creates a comprehensive non-combustible solution. This is crucial for meeting UK building regulations and passing fire safety reviews, especially important in high-rise and commercial applications.
Sustainable design
The modular system, including the aluminium joists, is designed with sustainability in mind. The components are recyclable, contributing to environmentally conscious construction practices
