Due to the high density and homogeneity of concrete, this construction also offers outstanding sound insulation.
Concrete shelter walls provide optimum protection against pressure, exposure to radiation, heat, gas and mechanical impact. These doors ensure that he 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.
20 cm of concrete > 6.5 cm of steel > 110 cm of wood
NBC gas-tight seal
Designed and manufactured according to technical regulations of the Swiss Federal Office of Civil Defense
How it Works
Concrete filling occurs after door is installed on site
Requires specialized anchors (included) to install
Only when the concrete shelter wall is sufficiently set may the door leaf be filled with concrete
Complete installation guide with purchase
Protection Against
Air blast from conventional or nuclear weapons
Impact from fragments and debris
Ground shock, i.e. vibration of shelter which is subject to pressure waves propagated through the ground
Heat from fires and thermal radiation from atomic weapons
Nuclear radiation
Chemical and biological warfare agents
