Isocrete Composite K-Screed is a topping of Standard Isocrete K-Screed laid over a base of lightweight aggregate used for weight saving e.g. on roofs. Additional data sheets are available for Isocrete K-Screed for weight saving, for impact sound installation, for thermal insulation and for underfloor heating.
Screeds should be isolated at all edges, abutments and columns to allow for movement due to thermal loadings. The manufacturers’ guidance for both the floor screed and the tiling must be followed to determine the minimum thickness of edge strip required to allow for expansion. This will typically be between 6-15mm.
