Diasen, based in Italy, have been manufacturing cork and lime-based breathable plaster systems since 1985. Diasen's philosophy centres around sustainable construction materials and producing innovative products with a low environmental impact. Diasen supply a range of sustainable products which include thermal and acoustic insulation solutions and waterproof coatings for both public and commercial buildings. Diasen Thermal Plaster, Diathonite, does not impede the ability of a wall to breathe. This is particularly important when dealing with solid brick or stone walls, which utilise lime mortar and lime plaster systems. Unlike many modern impervious thermal insulation systems, Diathonite thermal insulating plaster, is a breathable insulating plaster which provides the optimum combination of both thermal performance and moisture management.
