ZK Boden klein Inter Flexa-cavity floor/
Special features

The Inter Flexa cavity floor unites the advantages of a false floor with those of the monolithic cavity floor and is a very economical system for normal static loading and stressing in the field of construction of offices and administration buildings.
Special gypsum boards are placed as permanent formwork on the height-adjustable steel supports and covered with a masking course. The understructure which is thus already conditionally suitable for foot traffic is then covered with floating screed to the required level. Irregularities of the unfinished floor are compensated for by the steplessly height-adjustable steel supports.
Heating pipes can be bridged particularly easily with the Inter Flexa-cavity floor in the facade junction area. There is no need for partitioning or loose fills in the area of the heating pipes

The support grid spacing is 60 x 60 cm.

The gypsum boards have
a size of 60 x 120 cm x 1,8 cm.
