For better ventilation, shock joints are placed during the joints during the building to provide sufficient ventilation to the masonry. These so-called shock joints offer wasps, mice, hornets and other rodents an optimal access to the space between a two-layer masonry. By removing the thermal insulation by nesting etc. cold bridges are created in the masonry, which promote moisture and mould formation. In order to protect your masonry from these unsolicited guests, we have developed this grout grid. It is made of high quality polypropylene, is unobtrusive due to its transparency, also weatherproof and frost-resistant. These joint fans can be inserted into the joint in minutes. Simply squeeze lightly into the grout, and you're done. The design of our products is protected by the German Patent and Trademark Office registered designs.
