For better ventilation, the house construction during the clinking process creates shock joints to provide the masonry with sufficient ventilation. These so-called shock joints provide wasps, mice, hornets and other rodents with optimal access to the space of a two-shell masonry. By removing the thermal insulation materials by nest construction, etc., cold bridges in the masonry are created which favour moisture and mould formation. To protect your masonry from these uninvited guests, we have developed this grout grid. It is made of high quality plastic, is discreet, as well as weatherproof and frost resistant. These joint fans can be inserted into the joint in minutes. Simply squeeze it slightly, insert it into the joint, and you're done. Instructions: 1. Cut joint fan to joint height if required. 2. Slightly squeezed into the joint. 3. If necessary. with a small screwdriver. Your joint is now protected.
