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.
