As the name itself suggests, Loft water tanks are ideal for installation on lofts or indoor construction. These tanks provide the supplementary water supply apart from the central storage tank, usually the overhead water tank. These tanks are made of High-Density Polyethylene (HDPE) and Linear Low-Density Polyethylene (LLDPE). When these are made by Roto moulding then the material used is LLDPE and when the process of blow moulding is applied, the material used is HDPE. The material used in these water tanks makes them resistant to corrosion from water and other agents, and these also provide a chemically inactive and safe storage medium.
