Solutions to Thermally Efficient Building Envelope Details

Building envelope thermal performance is greatly affected by thermal bridging, or localized areas of increased heat flow through walls and roofs. Mitigating the impact of thermal bridging is not only necessary to reduce energy consumption but is also an important consideration for minimizing the risk of condensation on cold surfaces and for maintaining occupant comfort.

As part of new Building Envelope Thermal Bridging (BETB) Guide, various construction details have been analyzed to evaluate traditional thermal bridges and various solutions provided by Schöck Isokorb. Please find the report here.

The BETB Guide explores how the building industry can meet the challenges of reducing energy use in buildings, in part by effectively accounting for the impact of thermal bridging. It outlines how to effectively account for thermal bridging. For practitioners, it provides a catalog of common building envelope assemblies and interface details, as well as their associated thermal performance data.

In this new report provided by Morrison Hershfield, the most critical thermal bridges and their solutions have been evaluated, that means concrete balconies, concrete parapets and steel extensions connected to interior steel and concrete structures.

In the report, both the evaluation of heat transmittance and surface temperatures combined with the according risk of condensation has been evaluated.

The results show significant improvements by implementing Schöck Isokorb.
