Faut-il isoler un mur en pierre par l’intérieur ?

In this video, I answer a frequently asked question: can you insulate an old stone house from the inside? The answer is yes… but it’s not the first question you should ask. Before considering insulation, it’s essential to understand how old buildings work: the behavior of stone walls, the possible presence of cement, moisture management, rising damp, ventilation… All these factors directly influence the feasibility of the work. Through this concrete example, you’ll also see why insulation isn’t always the priority, and how to make the right choices to preserve your home, your comfort, and your finances.

As an author with Terre Vivante and host of the YouTube channel “Papy Claude,” I now devote myself to this sharing by building a network of professionals: the habitologists. The goal of this network is to help residents achieve their objectives: to attain comfort while significantly and genuinely reducing their footprint (greenhouse gas emissions, resource use, etc.), and to respect the relationship between residents and their homes (housing sustainability, budget, etc.). Former craftsman, former project manager, former timber frame house builder, holder of a patent for a prefabricated timber frame construction principle, trainer in ecological construction and insulation, author of articles...
