COFLEX CM By PROFILITEC
Collection: Coflex
Type: Modular movement joint for deep bed applications
COFLEX CM series is a modular system for deep bed installations which enables the realization of movement joints whose height perfectly matches the thickness of the screed + the tile covering. It is composed of a synthetic resin co-extruded profile - the base module piece CM 300 P, with a visible section made of full coloured softer resin material, and of a twin-profile CM 200 P open in its upper part, which works as the former clip extension piece. Settlements of the structure, expansion and compression due to thermal excursion, shrinkage and structural bending are elements that create continuous movements and stresses in the flooring, which often generate problems of cracking or premature detachment of the covering. It is therefore advisable to provide an adequate grid of expansion joints during installation, choosing the type of joint and its location in consideration of the loads and stresses to which the coverings will be subjected, and the different coefficients of linear thermal expansion of the bedding and tiles and the possible interactions between different materials. The splitting of the surface and the screed underneath is in fact decisive in order to guarantee a workmanlike laying in both adhesive and traditional methods. Always provide for a joint: - In correspondence with a change in the substrate material and/or the joints. - At pre-existing discontinuities in the substrate, such as structural expansion joints and different screed blocks. - At fixed elements such as columns and doors. - At changes in the laying direction. - At points where the tiled surface meets walls or containing elements. The resulting modules should be as even as possible. In general, the proportion between the two sides should not exceed 2:1.
