COFLEX CR By PROFILITEC
Collection: Coflex
Type: Cove base corner joint
COFLEX CR series is expressly conceived to perimeter joint wall/floor coverings supplying sufficient elasticity for the expansion and meeting the cove base hygienic corner cleanliness requirements. It also serves as a sound breaker of the covered surfaces so that trampling of foot steps is not transmitted to the adjacent walls. COFLEX CR consists of a main curved co-extruded hard/soft combination module Art. CR 16 with Art. series KJ inserts which slide into CR 16 tracks allowing it to adapt to any covering height and providing a perfect anchoring to the tiled covering. Patented system. The modular combination system called "Clip System" allows one to match all possible tile thicknesses still with the same base mudule, thus resulting in both a time saver and actual material saved. The KJ -Kerajolly profile functions as the perforated side flanges for the laying so to adapt to the different heights of the tiles for wall and floor coverings (e.g. floor height 12,5 mm - wall covering height 8 mm). KERAJOLLY small off-cuts can also be utilized for this purpose. E.g. of COFLEX assembly for installation: if the thickness of a tile is of 10 mm, utilize the KERAJOLLY KJ 8 mm height profile as the combination with the CR base module raises the height by 2 mm matching it then to the 10 mm tile thickness. 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.
