Ceilings for clean rooms may emit only minute quantities of air-borne particles to meet the requirements for air purity that they have to comply with. Standard DIN EN ISO 14644-1 defines the maximum permissible limits for this. Many of OWA mineral ceiling systems are suitable for application areas requiring high and very high levels of air purity.
Additional information:
Selected OWA mineral ceiling systems achieve a purity level up to ISO 4 (according to DIN EN ISO 14644-1) and are thus qualified for many clean room areas. These products are high-quality wet felt products (mineral tiles manufactured with wet processing), whose components tightly bound. Additional edge sealing is not necessary for this reason.
