Shelter closures

Armoured doors and armoured covers protect the entrances and emergency exits of bunkers and shelters and provide protection against:

  • Air blast pressure waves from nuclear and conventional explosions

  • Radioactive primary radiation from nuclear power plant accidents and atomic bombs

  • Heat waves and fragments from nuclear and conventional bombs

  • Poison gas contamination from industrial accidents and military chemical warfare agents

Armoured doors, pressure doors and armoured covers consist of a steel reinforcement frame that must be concreted directly on site.

The installation of the armored door and the armored cover should be carried out during the basement conversion, since subsequent installation is hardly possible due to the high weight in the unconcreted state (armored door PT1, 200 kg).

In the best case scenario, the components are therefore encased in concrete in the basement during the construction of a new residential / commercial property.

Overview of shelter closures with armored doors, armored gates, armored covers from the German Shelter Center

Armored doors (PT)

Armoured doors seal the entrances to shelters/ nuclear bunkers / air raid shelters gas-tight and pressure-tight and are installed and concreted on the outside of the shelter. In the event of a pressure surge, the armoured door is pressed onto the shelter shell and protects the occupants.

The armored door is locked from the inside with two solid lever locks and is secured against entry from the outside with a locking device.

Armored doors are available in four different sizes (PT1 – PT4).

Armoured door PT1 (standard size for shelter entrances)

  • External closure for protective structures up to 3 bar

  • Armoured door with outward-facing hinge

  • Version with fixed or removable door threshold possible

  • Can be used left and right

  • Wall frame made of angle steel profiles with anchor plates

  • Door leaf with groove and sealing rubber

  • Welded reinforcement

  • Lever locks with locking mechanism

  • Tube for self-release device

  • Width: 80cm

  • Height: 185cm

  • Thickness: 20 cm

  • Weight without concrete filling: 200 kg

Armored door protects shelter and bunker from air raids, radiation protection, radioactivity

Self-release device

The self-escape device is required if the armored door is blocked by debris from the outside and it is not possible to leave the bunker even via the emergency exits.

With the self-release device, a blocked armored door (PT1 – PT3) can be mechanically pressed open up to a passage width of 35 cm.

Armoured sliding walls (PSW)

Armoured sliding walls (PSW) are installed in larger civil defence facilities, which are usually used as underground car parks for cars when there is no threat. In contrast to armoured doors, which are concreted into the walls of the shelter, armoured sliding walls are located in a floor and ceiling channel.

The production of the armored sliding walls takes place individually in Switzerland, which means that individual dimensions and customer requirements are possible.

Pressure doors (DT)

Pressure doors separate different shelter compartments from each other in a gas- and pressure-tight manner and are installed inside the shelter shell and lined with concrete. The difference to the armored door with a thickness of 20 cm is that the pressure door is designed with a thickness of 10 cm.

Pressure doors are used in locks and larger shelters and bunkers.

Pressure doors are available in three different sizes (DT1 – DT3).

Pressure door DT1 (standard size for shelter partitions)

  • External closure for protective structures up to 3 bar

  • Pressure door with outward stop

  • Version with fixed or removable door threshold possible

  • Can be used left and right

Armoured cover (PD)

Armoured covers seal the emergency exits of bunkers and shelters gas- and pressure-tight and are installed on the inside of the shelter shell and filled with concrete. If an armoured door is buried or blocked, the armoured cover can be opened inwards and allow people to exit the shelter.

Like the armored door, the armored lid is locked from the inside with two solid lever locks and secured with a locking device to prevent unauthorized entry.

Armoured lid PD (standard size)

  • External closure for protective structures up to 3 bar

  • Armoured cover with stop to the outside

  • Version with fixed or removable door threshold possible

  • Can be used left and right

Protective cover

With the help of a protective cover, existing basement rooms can be converted into temporary shelters. The cover is mounted over a basement window, which can protect the shelter occupants from pressure waves, (glass) splinters and, in combination with a ventilation system, from nuclear, biological and chemical warfare agents in the event of an incident.

In times of peace, the lid is open, allowing the window to be used in the usual way. In the event of a disaster or attack, the lid can be closed and the light shaft filled with sandbags.

The covers are custom-made to the dimensions of the respective windows. The number of locks and wall fastenings is determined individually as part of a static calculation.

Panic room – security doors, windows and facades

We offer special security doors, windows and facade elements for the construction of panic and shelter rooms. The security elements can provide combined protection against burglary, bullet holes, explosions, fire and smoke up to the highest security classes.

We work with various manufacturers depending on the requirements and protection concept. The tested and certified safety elements are manufactured individually in Germany for each construction project according to our specialist planning.

Classifications – Burglar resistance

Given the high number of burglaries and low detection rates, effective protection against attempted burglaries plays a particularly important role in building security.

In this security segment, we offer a wide range of tested and certified doors, windows, facades, grilles and many other security products.

Shelter and bunker ventilation

Shelter ventilation systems essentially consist of a fan, a pre-filter and a gas filter (activated carbon filter), which ensures the supply of fresh air in the shelter.

The ventilation system is electrically operated, with the air drawn in being processed by two filter stages. In addition, in the event of a power failure, the ventilation system can be operated using a hand crank.

First, the contaminated air is passed through the particulate filter, which filters out all suspended and contaminated particles from the outside air that is sucked in. The contaminated air is then sucked through the gas filter, where the activated carbon absorbs dangerous poison gas molecules.

The cleaned outside air is then fed into the shelter by the fan. The air overpressure in the shelter created by the intake also ensures that the used breathing air is discharged to the outside via an overpressure explosion protection valve.

In addition, a slight overpressure in the shelter (at least 50 Pa and a maximum of 250 Pa) ensures that no poisonous gases can enter from the outside, even through possible leaks in the shelter.

Depending on the concentration of toxins in the outside air, the gas filter (activated carbon filter) can be used safely for several days and weeks.

Shelters Shelter technology in Germany. Approved and certified. Protects against chemical weapons

Shelter facility

In non-threat times, shelters can be used as basement compartments, hobby rooms or as a protected storage place for electronic data storage devices, valuables, etc. In the event of a threat, the shelter can then be occupied.

Since it is assumed that the duration of stay in the shelter is limited, a toilet with water and sewage connections in the shelter can be dispensed with for cost reasons.

According to the Swiss shelter concept, shelters are normally equipped with dry toilets.

Additional heating is usually not necessary, as the enclosed shelter is tempered by the body temperature of the occupants.

Lying places, beds, sleeping in shelters and bunkers, safety while sleeping

Dry toilet (TC)

The dry toilets consist of a plastic waste bucket with a seat/lid and one or more sets of waste bags.

The water and chemical-independent system is extremely simple and therefore the optimal principle for emergency situations: A waste bag is placed in the insert and closed after use. The bag is then stored in the depot bucket, which is lined with a waste bag. The waste bucket is sealed airtight with a lid.

Depending on the size of the shelter, different dry toilet sets must be selected:

  1. Dry toilet TC 8: up to max. 10 people

  2. Dry toilet TC 15: for 11 to max. 20 people

  3. Dry toilet TC 30: for 21 to max. 30 people

Toilet cubicle

To match the dry toilets, there are toilet cubicles for the shelter.

Two variants are possible here:

  1. Fixed toilet cubicles

  2. Mobile toilet cubicles

During non-threat times, the fixed toilet cubicles can be used as lockable storage space for dry toilets and lying areas.

Berths for compulsory shelters

This berth offers an inexpensive and space-saving sleeping option in the bunker and shelter. There are two different versions:

  1. Version with fabric covering

    • Space-saving in non-threat times

    • Beds can be packed, e.g. stored in the toilet cubicles

  2. Version with chipboard

    • Can also be used as a storage rack during non-threat times

Sleeping accommodation in air raid shelters, nuclear shelters

Staff berths

For greater comfort, we also offer so-called "personnel beds". The shelter beds consist of 19 mm thick chipboard and a solid, shock-tested tubular steel construction.

The load capacity per level is 250 kg, which means the bed can also be used as a storage space.

These beds are available in the following variations:

  • 2-storey

  • 3-storey
