United
States Bullet Proofing dominated the competition
at Force Protection Equipment Demonstration IV
held at the Marine Corps Base in Quantico, VA.
United
States Bullet Proofing's blast window went three
for three at the blast demonstration range. The
same USAW400 Series window was subjected to a
50 lb blast of TNT at a range of about 35 feet
on all three days of FPED. Designed for a 12 psi
blast load the post FPED analysis has determined
that the actual blast was over 26 psi! There was
no visible blast damage to the frame or the glass,
even after the third blast. Flying rocks caused
only minor damage. We are quite proud to say that
United States Bullet Proofing was the only window
manufacturer that used the same window frame and
glass sample all three days. The glazing material,
provided by Globe Amerada, was held firmly in
place by the USAW400 frame system utilizing minimal
anchors, thus indicating the energy absorbing
capabilities of the window design.
While
no one can predict what size bomb and at what
distance it will be placed from a facility, an
estimate of the threat level must be utilized
to design a product to meet design blast conditions.
At United States Bullet Proofing we routinely design our
windows to retain the glazing material in the
frame following a blast. This serves a number
of purposes. First, as demonstrated at FPED, the
robust design allowed the same window to withstand
multiple blasts. (Is the terrorist going to bring
just one bomb?) Second, since the window is not
destroyed or blown in, it prevents compromise
of classified material inside and prevents intrusion
of the elements that could cause building and
equipment damage. Finally, it allows the building
to re-occupied immediately to maintain operations.
Our mission of Protecting People and Property
is thus achieved.
United
States Bullet Proofing has been in business since
1988 and offers of the largest product line of
Bullet, Blast, and Forced Entry Resistant doors,
windows and wall systems. In terms of ballistic
resistance, our systems can withstand up to a
UL 752 Level 8 condition, which is five 7.62 NATO
rounds, although our frames can take an unlimited
number of rounds. Our blast capability exceeds
the General Service Administration (GSA) Level
D requirement (the highest GSA level). With regard
to forced entry protection, we are quite proud
to say that we are only one of four companies
in the world, certified by the Department of State
to build forced entry resistant windows and doors
for overseas posts. Our products are also in use
in numerous Department of Defense facilities. |
