Lunor's components for the construction of protected premises are installed during the construction process.
They consist of a reinforced concrete shell made on-site so there can be as few openings as possible to protect the integrity of the shelter. Building regulations also require special closing elements for each of the openings. It is also possible to additionally install an armored door or an emergency door to an existing room - for example in the case of a remodeling/extension.

Bunker door PT-4 can be ordered only with a fixed sill.

The concrete walls of the shelters provide optimal protection against pressure, radiation, heat, gases and physical pressure. LUNOR security doors provide these excellent features and ensure that shelter entrances have no weak points. LUNOR explosion-proof and gas-tight doors are designed for civil defense and military shelters, and also meet industrial requirements. Various types of explosion-proof doors, explosion-proof covers and pressure doors as well as sliding walls are available. These doors are designed for high and medium levels of protection. Lunor explosion-proof and gas-tight shelter closure devices are concreted in place to ensure an optimal connection to the shelter. The fire resistance of concrete doors is excellent. The radiation in the room slows down and the door leaf does not deform even under strong thermal effects. Loaded by the fire, they prevent smoke from entering the shelter very effectively. Thanks to its density and homogeneity, concrete provides excellent sound protection. Concrete doors protect access to the shelter from detonation effect, and internally reduce the sound level very effectively in engine rooms, diesel engines, etc.
