Diathonite Thermactive.037 stands out as the pinnacle of thermal insulation plasters, combining cutting-edge technology with ecological responsibility. Made entirely from natural materials such as cork, diatomaceous earth, NHL5 natural hydraulic lime, perlite, pumice stone, siliceous fillers, and fibers, this plaster is designed for superior thermal insulation against both cold and heat. Its unique, highly porous composition utilizes air as an insulating medium, enhancing its thermal properties. With an exceptionally low thermal conductivity of 0.037 W/mK, Diathonite Thermactive.037 ensures reliable, long-term protection against environmental elements. It also absorbs and dissipates moisture, helping to maintain optimal indoor temperatures and reduce energy consumption year-round.
