Overflow tanks are used to collect water that flows over the edge of a swimming pool. SIMONA® Twin-Wall Sheets are the perfect choice for such Systems.

Thanks to the high rigidity of the material, no cross-ribbed or steel profile reinforcements are needed when engineering such structures. Among the key advantages of twin-wall sheets are their low weight, excellent stability and good chemical resistance to swimming pool water.

The flexural strength of a SIMONA® PE Twin-Wall Sheet (19 webs/8 mm outer skin) is about the same as that of a solid SIMONA® PE Sheet with a thickness of 40 mm. However, it has only half the area density, which makes transportation much simpler. The weight advantages of SIMONA® PE Twin-Wall Sheets compared to conventional cross-ribbed tanks can be up to 30 per cent.
