The described mineral boards are produced using the traditional wet-felt process by the three listed associa- tion members. The initial materials are mixed with water to a homogenous suspension that is then pumped onto a belt conveyor (Fourdrinier). The water is removed both mechanically (gravity and vacuum) and by evaporation in a drying oven. The process water is reused as much as possible. It is treated and refed into the process water circuit. The boards can be sanded, painted, patterned, eroded or perforated depending on the required appearance. Production waste and dust are reused in the production process.2.13 Useful life - reference The useful life of the mineral boards (wet-felt) is up to 50 years depending on application, loading and level of maintenance.2.14 Extreme influences
