Aluminum expansion joint COFLEX CMB

brassfor floor

This movement joint profile consists of a Resinil wide base flange which can be fitted under the mortar or screed bedding to subsequently host the synthetic resin co-extruded profile insert, with an extension piece for adaptation to the mortar bed height. Conceived to properly subdivide the screed, according to the minimum bays provided in the project and in correspondence of the cast-retakes. It works also as form-work, as its wide lateral flanges keeps it easily in the right position for cement casting. The lateral parts of the base module are in Resinil, while the linking insert is in softer synthetic resin Resinflex. The system can be adapted to virtually any given height, thanks to the modular clip device and to the use of the available extensions, with a minimum 30 mm height and subsequent clicks at 15-20 mm height intervals. In correspondence with screed-bed cuts and joints, it is always advisable to provide for an expansion joint also at floor level, such as a Coflex CA type, to prevent tensions accumulating on the surface along the underlying cut, with consequent cracking of the floor surfaces .
