About Terreal
Terreal is a company roof tile and roofing solutions manufacturer based in Suresnes (Île-de-France). Its activity focuses on its terracotta tiles and roofing components.
In roofing, waterproofing is a system, not a product: substrate, vapour barrier, insulation, membrane and protection must be detailed together, especially at junctions, outlets and upstands. Most leaks start at details, not in the open field, so supervising those points during construction is the best investment.
The roof should be considered part of the energy balance: continuous insulation, thermal-bridge control at upstands and junctions, and adequate ventilation prevent interstitial condensation. Vegetated or reflective solutions can help in warm climates, but loads, drainage and maintenance must be verified before adopting them.
