Folding lintels

In sandwich walls, external, inside which the thermal insulation layer is located, it is necessary to provide lintels of small thickness. Depending on the thickness of the façade and load-bearing wall, we set a different number of lintel beams, separating them with a layer of thermal insulation. Covering the lintel with four lintel beams in the wall made of Wienerberger Porotherm hollow bricks is very simple. The beams themselves are also a product of this company that is part of the entire system.
