Concrete shelter walls provide optimum protection against pressure, exposure to radiation, heat, gas and mechanical impact.
LUNOR shelter closures guarantee these excellent properties, making sure that entrances and exits are no longer shelter "weak points".
LUNOR shelter closures are delivered ready for installation by the local builder, who sets them in concrete together with the walls. In this way, the closures make up an integrated whole with the protective infrastructure.
Concrete excellently protects against radiation. It takes roughly the following material thicknesses to achieve the same effect against nuclear radiation.
closures = 20 cm of concrete) > 6.5 cm of steel > 110 cm of wood
Due to the high density and homogeneity of concrete, this construction also offers outstanding sound insulation.
