Publication of the practical sustainable development guide “Thermal bridges in new works and renovation – 2nd edition”

This new edition is a tool to raise awareness of the problem of thermal bridges in the building envelope, whether for new construction or renovation work.

Thermal bridges can cause significant energy losses through the envelope, they are the cause of problems linked to condensation and are a source of thermal discomfort. Treating thermal bridges is essential in new and existing buildings to reduce energy consumption and to preserve the comfort and health of occupants.

It is necessary to use existing but also innovative solutions, while ensuring that the essential performance of the structure is preserved in order to ensure the safety and health of the occupants.

This guide allows you to locate and quantify common thermal bridges by construction system in new and existing buildings. It offers a panel of treatment solutions and emphasizes the potential risks linked to the use of non-traditional solutions which would not benefit from a technical evaluation developed by a group of competent experts (Technical Assessment or Technical Appreciation). 'Experimentation).
