Metal Frame Floor Systems

Metal Frame Floor Systems are lightweight, high‑performance floor constructions designed to improve the acoustic, structural, and service integration capabilities of separating floors. These systems use galvanised steel channels or joists to create a stable, resilient framework that supports floorboards, acoustic layers and insulation materials. They are commonly used in both new‑build and refurbishment projects, particularly where enhanced impact sound reduction, airborne sound insulation, or service routing is required. Metal framing offers predictable performance, dimensional stability and ease of installation compared with traditional timber‑based solutions.

A typical metal frame floor build‑up may include:

• Galvanised steel floor channels or joists, often with integrated acoustic isolators.
• Resilient bars or clips to reduce impact sound transmission.
• Acoustic mineral wool insulation placed between joists or channels.
• Floorboards or acoustic decking, such as gypsum‑based boards or engineered panels.
• Optional floating floor layers for enhanced acoustic separation.
• Ceiling systems below the floor, often incorporating resilient fixings and plasterboard linings.

Key Features

• Lightweight construction that reduces load on the building structure.
• Consistent dimensional stability — metal components do not warp, twist or shrink.
• Improved acoustic performance, especially when combined with resilient layers and mineral wool insulation.
• Fast and clean installation, with components designed for simple cutting and fixing.
• Slim floor build‑ups achievable while still meeting acoustic standards.
• Suitable for both timber and concrete substrates, depending on system design.
• Service voids can be incorporated without compromising acoustic performance.

Typical Applications

• Separating floors in residential buildings, including flats and student accommodation.
• Refurbishment of older buildings where timber joists require acoustic upgrading.
• Mixed‑use developments where noise transfer between units must be controlled.
• Lightweight construction projects where reducing structural load is beneficial.

Metal Frame Floor Systems offer a reliable, modern and acoustically efficient approach to floor construction. Their combination of lightweight steel components, integrated acoustic features and compatibility with a wide range of floor finishes makes them a strong choice for projects where noise control, speed of installation, and long‑term stability are priorities.
