TECH Tank Roof Slab 80 kPa is a rigid stone wool slab for industry applications requiring high mechanical resistance such as flat tank roofs or other equipment with a maximum service temperature of up to 720°C. It combines premium thermal and acoustic efficiency with high compressive strength performance. TECH Tank Roof Slab 80 kPa is available with AS-Quality (Cl- <=10ppm) when in contact with austenitic steel structures. It was specifically designed to fulfill highly demanding requirements of Swedish standard SSG 7591 and CINI 2.2.01 usually used on multilayer systems for insulation of the storage tank roof insulation. The compressive strengths higher than 80 kPa, making it strong enough to withstand normal walking loads alone or combine with TECH Tank Roof 20 kPa (as a system) during installation and maintenance.
