The installation of fixtures in and on thermal insulation composite systems places special requirements on the fixings. Thermal bridges must be avoided and the loads that occur must be safely introduced into the load-bearing substrate. Light loads can be secured directly into the insulation using a special plug. For the fixation of medium-sized loads, the mechanical stand-off installation systems Thermax 8 and 10 are ideal. When securing heavy loads that are also exposed to high wind loads, the stand-off installation systems Thermax 12 and 16 are the best choice. These are safely anchored with the approved fischer injection mortars.
