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) T. N. T Charge’s weight ce n a t s i D f f Stand o

Examples of Blast Loads Charge weight 10 kg 100 kg Standoff 10 [m] 20 [m] 30 [m] Pressure [psi] 18 5 3 131 21 9 Impulse [psi*msec] 44 21 13 230 103 63

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.
