Claytec – Clay Plasters Mineral 20
Description
1. The Material: The Claytec system replaces conventional gypsum drywall and synthetic acrylic plasters with raw earth. The system consists of “Lehmbauplatten” (heavy clay boards reinforced with natural reed or wood fibers) and “Lehmputz” (raw clay and sand plasters). Unlike Portland cement or gypsum, which require massive amounts of energy (calcination at 150-1450 degrees Celsius) to alter their chemical state, raw clay simply dries via evaporation.
2. The Company & The Story: Based in Viersen, Germany, Claytec has been instrumental in standardizing and modernizing earth-building (Lehmbau) across Europe. They take one of humanity’s oldest building materials—raw earth—and apply strict industrial tolerances to it, supplying reliable, dimensionally stable products for modern commercial and residential construction.
3. Technical & Commercial Summary: Supplied as dry-mix bags (for plasters) and rigid panels (for drywall replacement), the Claytec system is targeted at B2B developers and architects focusing on pristine indoor air quality and zero-waste architecture. The boards can be screwed into timber stud frames just like standard drywall, then seamlessly finished with a thin coat of clay plaster.
4. Features:
-
Zero Chemical Curing (Infinite Reversibility): Because clay sets by drying rather than a chemical hydration reaction, a dried clay plaster can be wetted 50 years later, scraped off, and reused entirely without loss of quality.
-
Zero Portland Cement & Gypsum: Bypasses the massive CO2 emissions associated with clinker and the landfill issues of synthetic gypsum boards.
-
Passive Humidity Regulation: Clay is one of the most highly hygroscopic materials available. It rapidly absorbs excess indoor humidity and releases it when the air dries, passively preventing mold and regulating the indoor climate.
-
Thermal Mass: Provides significant density to lightweight timber-frame structures, helping to stabilize indoor temperatures.
