Core Competencies
• Designing protective solutions for building infrastructure and personal military use.
• Developing protective systems that cope with future large-scale threats.
• Live-testing, full-scale blast & ballistic testing programs.• Advanced, patent registered technologies .• Engineering, manufacturing & project management
capabilities and services.• 33 years with an impeccable track record of thousands of
projects meeting strict blast and ballistic requirements.
Our Main Markets• Embassies• Government and federal buildings• Barracks• Public buildings and commercial centers• Oil refineries• Banks• Sport halls/stadiums• Military installations• Transportation terminals and stations• Theaters• Religious institutions
Why Worry..?
• Terrorism worldwide since 1970 (source MIPT)23,876 incidents; 83,130 injuries; 32,649 fatalities
• Bombing attacks– Car Bombs– Suicide Bombers
• Explosive materials– Readily available– Affordable– Easy to use– Difficult to detect
What Was Needed
A solution for eliminating the hazards from concrete and brick debris that follow a blast event.
The Design Challenge
Balancing between the following requirements:• Security• Functionality• Aesthetics and Environmental
Friendliness • And….. Costs.
Protection Design (1)
The charge’s weight and the stand off distance define the Pressure (psi) and the Impulse (psi x msec)
Charge’s weight
Stand off Distance
T.N.T
Examples of Blast Loads
100 kg 10 kg Charge weight
30 [m] 20 [m] 10 [m]
30 [m]
20 [m]
10 [m] Standoff
9 21 131 3 5 18 Pressure [psi]
63 103 230 13 21 44 Impulse [psi*msec]
Protection Design (2)The heavier the charge, the longer the blast duration. The shorter the stand off, the higher the pressure. Changing the charge’s weight and it’s location relatively to the target, influences the blast characteristics.
The Solution: Ballistic Wall Covering
Innovative, patented technology using composite materials for protecting and shielding people within a building from blast event hazards.
Advantages
• Withstands the highest blast levels—more than 300 psi*msec (Impulse).
• Offers best protection to walls integrated with blast-proof windows and doors.
• Reduces substantially hazards from wall debris in case of a direct hit from shoulder-launched anti-tank weapons.
• Can be used and installed rapidly by infantry troops in “hot zones”(In-use by the I.D.F).
Characteristics & Use
• Ideal for retrofit projects and for protecting historical buildings.• Can be applied in banks to protect safe rooms.• Offers engineering flexibility in meeting architectural design
specifications.• Can be used to reinforce infrastructures against earthquakes. • Eliminates the need to use heavy and massive framing methods
for blast reinforcement of existing walls.• Very cost effective. • Environmentally friendly.• “Breathing” (porous) material which maintains room ventilation. • Can be decorated and painted with commercially available
paints.• Flame retardant and fungi resistant.
