An alternative to conventional external thermal insulation composite systems is the brick façade insulation Poroton-WDF developed by Schlagmann. It consists of diffusion-permeable brick shells filled with perlite, a rock of volcanic origin. The façade insulation is bricked up like a flat brick wall using the thin-bed method. The material is purely mineral and non-flammable. Due to the typical brick property of absorbing heat and condensation, storing it and releasing it again with a time delay, it offers natural protection against fungal and algae formation. The brick shells, which are covered with lightweight plaster on the outside, are also particularly robust (impact-resistant) and hardly at risk of plaster cracks.
The dissipation of horizontal loads, e.g. by wind pressure/suction, is carried out as with external thermal insulation composite systems via the anchoring with dowels in the load-bearing substrate. Due to the significantly higher dead weight compared to external thermal insulation composite systems, the vertical load transfer of the brick façade insulation is carried out via foundations, in-situ concrete beams or special stainless steel brackets.
