TANK Roof INSULATION

For tank roofs, in order to cope with possible foot traffic, we recommend PAROC Pro Roof Slabs, with high compression resistance. Exact type, thickness and number of layers depending on design details and operating requirements. This enables asset-owner, engineer and insulation contractor to fulfil specific requirements according to specifications. A typical solution is the use of PAROC® Pro Roof Slab (WR) 50 kPa for the entire roof surface and for all layers. This product limits the deformation to maximum 10 % under a 50 kPa load. Please consult the respective product data sheet for more information.

Alternatively, a relatively thin top layer (20 mm minimum) of PAROC® Pro Roof Slab 80 kPa could be applied over one or more underlying layers of PAROC® Pro Roof Slab (WR) 20 kPa. The slabs themselves do not normally need any fixing, but the cladding should be anchored to the tank roof through the insulation layer. When, due to geometrical reasons (e. g. if too small radii are involved), the application of rigid slabs is not possible, semi-rigid slabs for example PAROC® Pro Slab 450 (WR) or flexible slabs for example PAROC® Pro Slab 350 (WR) or PAROC® Pro Wired mats can be used instead. To ensure foot traffic in those cases, supporting structures should be implemented. These supporting structures can vary according to different specifications and standards.

Based on our certifications to ISO 14025, ISO 21930 and EN 15804, we have received the Environmental Product Declaration (EPD) numbers NEPD-4100-3121-EN and NEPD-4101-3121-EN.
