The Knauf GIFAfloor Hugo & FHB18 Overlay System is a high-performance dry screed solution designed to upgrade existing raised access floors (RAF) by providing a stable, non-combustible substrate for continuous or hard finishes.

Manufactured from low-carbon gypsum fibreboard, Hugo and FHB18 panels combine lightweight construction with high density and strength. The panels feature an advanced tongue-and-groove joint, enabling quick, screw-free installation while creating a robust, monolithic surface suitable for almost any finish.

Variants

GIFAfloor Hugo: Available in 18 mm and 23 mm thicknesses, with a density of 1100 kg/m³. Suitable for general pedestrian/foot traffic areas.
GIFAfloor FHB18: Higher density option at 1500 kg/m³, providing enhanced structural loading capacity and durability.

An additional Knauf WF 10 mm wood fibre acoustic resilient board can be used beneath Hugo or FHB18 to achieve impact sound reduction of 21 dB, creating an acoustically rated overlay system.
