EHS & Quality
AL TAZI Rock Wool products are produced to comply with technical requirements of the American standard ASTM C168, ASTM C612, ASTM C547, ASTM C592, ASTM C665,ASTM C553, international European standard BS EN13162, and Saudi Standard SASO-GSOEN13162.
The management of Al Tazi Rock Wool Factory have the goal to achieve and maintain the highest quality standards. ARW is certified for the quality management system according to ISO 9001-2008 standards, all the procedures related to the standard are fully implemented in all related processes including purchasing, supplier approval / evaluation, production, quality control, contract review, handling, storage, calibration, customer satisfaction, and customer complaints, product traceability, non-conforming raw materials / products.
The products are continually inspected on production line by quality team, to insure that all packed products comply with customer requirements; samples are frequently collected and tested in our laboratory which is equipped with high sophisticated testing instruments. The tests are conducted according to the related standard test methods, factory product control (FPC) as stated by EN 13162 is implemented showing the required tests and the frequency of testing.

Environment Friendly
No harmful industrial wastes are produced from Al Tazi Rock Wool production processes, the solid wastes are efficiently recycled as per LEED requirements, the exhaust gases are treated and reduced to the international acceptable limits. The use of Rock Wool as a thermal insulation significantly reduce the environment pollution due to decrease of the energy consumption, reducing the emitted gases from power plants.
