COFLEX CTR expansion joints with grindable rubber insert

COFLEX CTR expansion joints with grindable rubber insert

Metal expansion joint with grindable insert, very resistant to the passage of loads. Ideal for ceramic tiles. The sturdy continuous metal corners protect the edges of the tiles, marble or stone and reduce mechanical stress, which in the presence of intense traffic risks compromising the integrity of the flooring. The metal side parts consist of a trimtec-type profile with a rounded upper edge and shearing to absorb high loads and tensions that affect the flooring making a single body with the adhesive and the tiles. The expansion zone in EPDM has excellent hardness with the right compromise between flexibility and strength. The height of the joint to be used must be chosen in correspondence with that of the flooring to be used and the quantity of thin set used for laying, the profile must in no case protrude from the flooring surface but must be less than approx. 0.5 ÷ 1 mm. The suggested backgrounds are based on the UNI 11499: 2016 standard: Indoor environments: 5m x 5m up to 6m x 4m External environments: 3m x 3m up to 4m x 2.5m Considering - Tile format - Joint width - Characteristics of the thin set - Support properties The size of the insert that can be sanded 5 mm involves a reduced visual impact but suggests its use in medium-small environments (shops, common areas, homes, private remittances) where the movements that the joint must compensate are also reduced even though with high loads to support.
