Premier Security & Fire Consultants Ltd: Pioneers in UK Blast-Resistant Solutions EXV10, EXV15 AND EXV25.

Curtain-walling/Glass Screens/Doors/Louvres

Premier Security & Fire Consultants Ltd has an extended portfolio of blast-tested security products including curtain-walling (EXV 10); Glass/screens (EXV 25); Doors (EXV 25); Louvres (EXV 15-25) cementing their position as the UK’s leading provider of blast-resistant products.

Premier Security & Fire’s Ultimate High-Security curtain-walling system has now successfully passed EXV 10 Blast examinations following testing with Patrick Mann Associates.

Premier’s curtain-walling already achieves LPS1175 E10 (SR5) to B3 (SR2) security and is certified to 20 metres high with unlimited screen width. It also achieves ballistic FB7 standard and was recently successfully tested to resist 762.51mm AP (Armoured Piercing) penetration. It has a U-Value of 0.5 –1.0 and now, with blast-resistance of EXV 10, it places Premier as a market leader with competing UK companies only able to offer curtain-walling to EXV 15.

Further testing in 2024 will enable Premier Security & Fire Consultants Ltd to include air and water resistance to hurricane-force levels in their curtain-walling.

Premier’s curtain-wall system can be used for:

  • Military operations room
  • Communications room
  • Guardroom
  • Secure offices
  • Armoury
  • Holding room
  • Safe room
  • Medical room
  • Dangerous good storage

In the realm of security and safety, Premier Security & Fire Consultants Ltd stands as a beacon of innovation, producing market-leading UK blast-resistant solutions that set industry standards. Our wide range of products includes fully glazed and solid doors, screens, and louvres, each engineered to perfection. What truly sets Premier apart is the incorporation of ballistic resistance in our designs, ensuring that our products can withstand both fragmentation and blast pressure, making them the ultimate choice for safeguarding critical infrastructure.

Meeting Stringent Blast Resistance Standards

Our commitment to excellence is reflected in the certification of our products to withstand peak blast pressures of EXV 10, EXV 15, and EXV 25. Blast pressure and overpressure are quantified using various units, with kPa (Kilopascals) and PSI (Pounds per Square Inch) being the most common. Premier’s solutions exceed expectations in each of these categories, offering unparalleled protection against the most extreme forces.

The Fragility of Glass in Explosive Incidents: Implications and Solutions

Explosive events have long served as a favoured tactic of terrorists, and regrettably, this unsettling trend is likely to persist in both the short and long-term future. The widespread destruction generated by these incidents often secures global media coverage, providing terrorists with a platform to convey their political messages to the public. The ease of acquiring ingredients for homemade bombs on the open market, coupled with the ready availability of bomb-making techniques on the internet, amplifies the danger. The scale of devastation hinges on the method of delivery, ranging from small post and satchel bombs to large vehicle bombs that can transport substantial quantities of explosives to their target, often evading detection.

Vulnerability of Modern Building Structures

Contemporary architectural designs often feature large openings to ensure adequate interior lighting and ventilation. While this design choice enhances occupant comfort, it simultaneously heightens the susceptibility of buildings to explosive incidents. In such circumstances, windows are frequently the initial structural components to succumb to the force of a blast wave impacting the building’s exterior. This vulnerability arises from the fact that windows generally break at lower pressures compared to other structural elements such as floors, walls, or columns.

High-velocity glass fragments, propelled by the explosion, have been identified as a significant cause of injuries in these scenarios. In urban areas, falling glass poses a significant hazard to pedestrians on sidewalks below and complicates post-incident rescue and cleanup operations by leaving large amounts of glass debris in the streets.

The Role of Glass Facade Design

Despite modern buildings being designed to withstand specific pressure levels, the prevailing structural design principle dictates that windows should be the weakest point in the wall system. This approach ensures that the wall fails before the glass facade does, as wall failure is generally considered less perilous. Consequently, there remains a compelling need to implement protective measures to mitigate the potential consequences of glass breakage during explosive events.

Understanding the Dynamics of a Bomb Detonation

When a bomb detonates, the explosive material is transformed into an intensely hot, dense, high-pressure gas that rapidly expands at extraordinary velocities, seeking equilibrium with the surrounding air. This swift expansion creates a shock wave comprised of highly compressed air, which radiates outward from the source at supersonic speeds. Notably, only one-third of the chemical energy present in most high explosives is released during the detonation process, with the remaining two-thirds released more gradually as detonation products mix with air and ignite. This after-burning process has minimal impact on the initial blast wave but can affect later stages of the blast wave, particularly within confined spaces.

The Blast Wave and Its Effects

The explosion generates an incident blast wave characterized by an almost instantaneous transition from atmospheric pressure to a peak overpressure. As the shock front expands, pressure gradually returns to ambient levels, resulting in a negative pressure phase that often persists longer than the positive phase. When the shock wave encounters a building or structure facing the detonation source, it reflects and reinforces, producing a maximum reflected pressure. The magnitude of this reflected pressure varies with the angle of the structure in relation to the detonation, as well as the peak pressure, which depends on the explosive’s weight and the distance from the charge. Closer proximity to the charge leads to higher reflected pressures.

Injuries Resulting from Shattered Glass

The severity and nature of injuries sustained in explosive incidents are closely tied to the extent of structural damage. The high-pressure air blast that enters through shattered windows can lead to eardrum damage and even lung collapse. As the air blast damages building components, it generates projectiles that can cause impact injuries. Airborne glass fragments are particularly notorious for causing penetrating or laceration-type injuries, while larger fragments may cause non-penetrating or blunt trauma injuries. Additionally, the air blast pressures can forcefully propel occupants against objects or cause them to fall, resulting in further injuries.


Explosive incidents remain a sobering reality in today’s world, and the vulnerability of glass in modern buildings exacerbates the risks associated with these occurrences. Recognizing the potential consequences of glass breakage during such events underscores the importance of enhancing building design, implementing safety measures, and raising public awareness. As we continue to grapple with the threat of explosive incidents, addressing the fragility of glass in contemporary structures becomes an imperative step in safeguarding both property and lives.
