18mm Knauf Gifafloor 18 is a high performance high density gypsum fibreboard floor panel used to create raised floors over pedestals with incredible strength. it is a high-quality, interlocking tongue and grooved floor board system bonded together to form a flat screed like surface. Knauf Gifafloor provides floor systems ideal for stone floors laid without requiring additional de-bonding layer. Simply glue the edges to receive a single layer floor. It is ready for foot traffic within 12 hours and ready for floor finish within 24 hours. Loading performance can be increased by using pedestals at reduced centres. Additional strength is also possible by adding an extra panel layer laid perpendicular to the first.

Knauf Gifafloor high density panels also deliver high acoustic performance when installed over acoustic batten or resilient layers. It also has superb fire resistance, with a non-combustible A1 fire rating. It is ideal for use with underfloor heating systems. The heating system can be commissioned faster and floor finishes laid within hours of installation, instead of weeks.Note: Not suitable for areas of high humidity
