Critical National Infrasture, Banks, Museums, Military, Government and Retail Security Shutters

Choosing the right specification for a retail security shutter or other type of security shutter depends on a number of factors including the industry sector, site specific security risks and frequency of operation. At Gilgen Door Systems our highly experienced team of roller shutter specialists work with architects, security consultants, engineers, contractors and building managers to integrate physical security such as retail security shutters appropriate to the level of threat faced by different buildings. The following commentary highlights some of the main considerations by industry sector. Contact us for further advice.

National Infrastructure

Critical National Infrastructure (CNI) is defined as those critical elements of infrastructure, the loss or compromise of which could result in a) major detrimental impact on the availability, integrity or delivery of essential services and / or b) significant impact on national security, national defence, or the functioning of the state.

Types of facilities include: Communication centres, Emergency Services, Energy, Water supply, Financial services, Government, Health, Transport, Defence, Civil Nuclear, Chemicals

Sites of national importance and / or delivering critical services normally have the security level set for them by CPNI in order to indemnify the government and ensure adequate protection of key national assets. Concealment and reduction on the impact of the environment are other important considerations.

Sector Considerations:

  • Site specific security normally SR3 and above
  • Insulation or acoustic performance
  • Curtain finish e.g. anti-corrosive, stainless steel
  • Ballistic or blast protection where necessary to satisfy a specific higher threat
  • Wind resistance for exposed facilities
  • Lock down technology


Banks and financial centres have an obvious duty to protect their facilities and assets from theft and normally engage security consultants to review the whole of their security arrangements.

Naturally the security rating on doors and entrance systems would be set very high and combined with other forms of security such as HVM (hostile vehicle measures), video surveillance, alarms and other deterrents. The recent Hatton Garden Safe Deposit Burglary where a non security rated shutter was forced open demonstrates the need to continuously evaluate security measures on old and well as new properties.

As criminal technology and techniques emerge banks and financial services need to ensure their properties remain adequately protected. Gilgen supplies a wide range of automatic doors, personnel doors and shutters to help protect the whole building.

Sector considerations

  • Minimum SR2
  • Choice of drive system
  • ASL (Automatic self locking) to prevent jacking
  • Minimum support structure
  • Curtain finish for aesthetics
  • Shutter positioning – front / behind glazing



Buildings that house priceless works of art and irreplaceable historical artefacts have a requirement to protect themselves from professional forms of theft. High levels of layered security will also be specified as part of any insurance policy. Because many buildings are also of significant cultural and historical importance often with very high volumes of visitors, they must also consider the threat of other forms of threat such as terrorist attack. Security consultants would normally specify a minimum of SR4 rated physical security alongside other forms of layered deterrents such as CCTV, guards and alarm systems.

Finally the aesthetics of the shutter and integration with the fabric of the building is an important consideration given the high levels of visitors and importance of design to culturally significant buildings.

Sector considerations

  • Site Specific Security – Minimum SR4
  • Ballistic or blast threats
  • Choice of drive system according to available space, frequency of use and shutter size
  • Curtain finish e.g. profiles types, colour, stainless steel
  • Minimum support structure
  • Integration with building management systems
  • Lock down technology to prevent lifting / jacking



Security shutters for defence and military applications have the dual role of protecting equipment and personnel from attack through the highest levels of physical security. Defence applications include army, navy and RAF bases, storage facilities, training centres, intelligence facilities, communication centres and facilities overseas that support forward operations.

The level of threat posed to these buildings normally demands a very high security rating for door protection of SR4-SR5 depending on the type of facility, location and other security measures. Rolegard SR5-B is the first LPS1175 SR5 rated security shutter to be launched with a certified ballistics rating and also offers inherent blast protection properties.

The ASL (automatic self locking) technology on Rolegard SR4 and SR5 shutters prevents lifting or jacking of the shutter in the closed position and locks down facilities automatically without the need of secondary locks. ASL improves protocol and helps reduce the risk of human error when locking down facilities.

Sector considerations

  • SR4-SR5 Security rating depending on site specifics
  • Ballistics rating (FB3 standard FB4 option)
  • Blast Protection
  • Insulation / weather protection for exposed locations
  • ASL (automatic self locking)
  • Shutter strength to deter possible crowd attack


Buildings that house government employees are considered as key assets of critical national infrastructure as they are vital for keeping the country running. The CPNI is responsible for setting the security level of government facilities backed by law and all types of door entry measures would be included in this remit.

Depending on site specifics and other security measures a security rating of SR2 and above would be standard. In additional to protecting employees the government has a responsibility to protect sensitive personal information and other assets which if compromised could adversely affect national security.

Panic rooms protected by security doors or shutters can be specified for foreign embassies and other buildings which need to protect staff.  Gilgen Door Systems can supply a comprehensive range of security rated automatic doors and personnel doors to protect the whole of a facility.

  • SR2 security and above
  • Ballistics / Blast Protection depending on site
  • Insulation to improve environmental factors
  • Activation methods
  • ASL (automatic self locking)
  • Shutter strength to deter possible crowd attack


Retail Security Shutters /Commercial

Jewellers, electrical outlets, car dealerships and other high value commercial premises have to consider the level of security required during night time / non trading hours. The level of security is determined by the level of risk associated with the location of the premises and value of stored products.

Where the building houses high value stock and is located in an exposed position it’s advisable to specify higher levels of physical security in the form of retail security shutters with at least an SR2 rating. Retail security shutters are often positioned behind shop front glazing to ensure concealment and aesthetics during normal trading hours.

Sites located in exposed locations should consider hostile vehicle mitigation measures and CCTV alongside retail security shutters to deter this kind of attack.

Sector considerations

  • Minimum SR2 for high risk / exposed applications
  • Tubular drive systems to minimise internal space requirement
  • Curtain finish for aesthetics
  • Shutter positioning – behind glazing or as perimeter vehicle access doors
  • Choice of locking system
  • Shutter strength to deter possible crowd attack


Ports and Terminals

Security at airports, sea ports and rail terminals requires special consideration due to the risk of terrorist attack and other forms of criminal activity. A successful attack could have a significant impact on transport networks and the risk is further heightened by having large numbers of people congregating in concentrated areas.

The CPNI would assess the security risk of sites deemed in the national interest and set an appropriate security level. Transport owners and operators also need to evaluate their own security to protect key assets, people and goods in transit. Security shutters are often specified on high value storage areas such as customs and bonded warehouses to target hardened these facilities and reduce the security threat.  The security rating of these facilities is determined by a number of factors including the value of goods stored and other security measures.

Sector considerations

  • SR2-SR4 depending on application
  • Blast Protection
  • Insulation / weather protection for exposed locations
  • ASL (automatic self locking)
  • Shutter strength to deter possible crowd attack
