COPRITEC CP By PROFILITEC
Collection: Copritec
Type: Expansion joint covers
COPRITEC CP - In industrial and commercial flooring, in the large continuous beam bays, and wherever two different bearing structures are linked together, a separation joint cover is often required, to allow linear expansion movements of neighboring materials. This profile is supplied self-adhesive, with a special adhesive glue which ensures remarkable movements absorption. For screw-and-dowel installation it is advisable to fix the profile to one of the two structures drilling it along the length only on one side, leaving the other side free for the slip and expansion movements. This profile is also suitable for bumper guards for stretchers in hospitals or as wall protection in schools and offices. 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 that often generate problems of cracking or premature detachment of the covering. It is therefore a good idea 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 cladding will be subjected and the different thermo-hygrometric linear expansion coefficients 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 the adhesive and traditional methods. Always foresee a joint - In correspondence with a change in the substrate material and/or the casting joints. - In correspondence with 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 regular as possible. As a general rule, the proportion between the two sides should not exceed 2:1.
