Diathonite Screed is a fiber-reinforced, eco-friendly, breathable screed composed of natural materials such as cork, natural hydraulic lime, clay, and diatomaceous earth. Designed for thermal and acoustic insulation, it’s ideal for both internal and external floor applications. Diathonite Screed provides excellent thermal efficiency by insulating floors against temperature variations, and its breathability ensures resistance to mold and moisture. Highly workable, it can be applied by hand or with a plastering machine, and it offers great durability for use on concrete slabs, foam glass aggregates, and other surfaces. This product is perfect for increasing the comfort and energy efficiency of homes and commercial buildings.
