Choose the correct insulation density
Tank walls are often very high. Due to temperature differences between the insulation and cladding, the so-called chimney effect, where air flows upwards, occurs. Because of this, it is important to use dense enough insulation slabs to prevent air movement inside the insulation, and to minimise heat convection (see graph).

Tank wall insulation can be installed with different fixing and supporting methods. These vary from country to country and depend on the specifications used. In this picture, insulation slab are fixed with welded pins.
