The Knauf GifaFloor FHB Structural Screed Board System is a high-density gypsum fibreboard (≥1600 kg/m³), engineered to deliver exceptional load-bearing capacity, dimensional stability, and fire resistance. This advanced flooring system is a dry-installed alternative to traditional screed, offering a high-performance structural surface suitable for a wide range of commercial and residential applications.
Knauf GifaFloor FHB panels are available in thicknesses of 18 mm, 25 mm, 28 mm, 32 mm, and 38 mm, providing flexibility to suit different load requirements and installation methods. The precision-engineered tongue-and-groove edges allow for seamless interlocking, creating a flat, monolithic surface without the need for mechanical fixings.
Versatile Installation Options
1. Hollow Floor System (Pedestal Installation)
Knauf GifaFloor FHB can be installed as a hollow floor system, directly supported by adjustable pedestals. This configuration creates a service void beneath the floor, allowing for the integration of electrical, mechanical, and plumbing services.
The high load-bearing capacity of the system makes it ideal for applications where accessibility and flexibility are key, such as offices, hospitals, schools, airports, and commercial spaces. With fire ratings up to REI 90 and enhanced acoustic insulation, it provides a robust and safe flooring solution while maintaining a lightweight construction compared to concrete floors.
2. Self-Supporting System (Cradle and Batten or Direct to Joists)
Alternatively, Knauf GifaFloor FHB can be used in a self-supporting system, installed over cradle and batten, timber joists, or metal substructures. This makes it an excellent choice for residential, modular, and off-site construction projects, offering a dry screed solution that enhances floor stability and acoustic performance.
Its high compressive strength and rigidity allow it to span across supports without excessive deflection, making it a cost-effective and efficient alternative to traditional wet screeds. The system is also thermally transparent, meaning it is highly compatible with underfloor heating, ensuring efficient heat transfer and reduced energy consumption.
