Energy losses occur at localised weak points in the building envelope where the thermal conductivity is higher than in the adjacent structure, e.g. balcony connections, columns or façade anchors. These weak points are referred to as thermal bridges. They increase energy losses from buildings due to their higher thermal conductivity which in turn lowers the surface temperature in the interior. This poses a high risk of mould, health risks and restricted living comfort. Condensation can also form and the building fabric could be damaged.

A distinction is made between „geometric thermal bridges“ and „material thermal bridges“. Balconies and pergolas are among the most critical areas in buildings in terms of thermal bridging as they represent a combination of geometric and material thermal bridges. It is therefore particularly important to ensure that these areas are thermally isolated to avoid high energy losses.

An equally large share of energy in a building is lost via structural thermal bridges which occur when load-bearing forces are transmitted through the insulating plane. This therefore happens in the vicinity of structural connections, i.e. balcony cantilevers or roof/external wall connections. Schöck offers efficient solutions for thermal isolation of components in all these areas. These components then no longer belong to the heated volume of the thermal building envelope and heat losses are reduced.

From thermal separation of balconies to thermal isolation of reinforced concrete walls and columns through to energy-efficient fastening of core-insulated concrete façades and back-ventilated curtain wall façades: Schöck eliminates structural thermal bridges with the product solutions Isokorb®, Sconnex® and Isolink® and thus makes an essential contribution to reducing energy losses, climate protection and sustainability.
