Tuffeau needs careful treatment
Tuffeau is a soft, porous limestone. Cement render or vapour-tight insulation accelerates its decay. We recommend breathable renders and insulation, after examining rising damp.
Centre-Val de Loire
Energy audits and DPE in Centre-Val de Loire
Centre-Val de Loire is known for characterful buildings — tuffeau limestone, brick, stone — in a more continental climate than the coast, with colder winters and hotter summers.
Temperature swings and summer comfort
Summers are hotter than on the coast, so summer comfort becomes a design criterion in its own right: shading, thermal mass and night ventilation before any thought of air conditioning.
Village houses and small blocks
Terraced village houses raise particular questions: party walls, street façades that cannot be insulated externally, narrow courtyards. The study works within those real constraints.
Frequently asked questions
Can a tuffeau façade be insulated externally?
Rarely in a historic centre, for heritage and moisture reasons. The study then compares breathable internal solutions with other improvements.
