Deer Park, WA - February 08, 2012
Knight Wall Systems today announced that its DOW™-Knight CI-System rain screen system has passed shock-tube blast testing – also referred to as over-pressure testing – a crucial government-mandated criteria for building envelope products specified for military facilities, hospitals and other federal buildings.
Knight tested its CI-System with three core cladding products – terra cotta, metal and brick panels. All three passed, meeting the most stringent criteria for blast testing using a shock tube.
“Shock-tube blast testing is mandated for government buildings and hospitals as an anti-terrorist measure,” Knight Wall Systems president Doug Knight said. “It’s not common for a rain screen system to be tested, but it’s really one of the most important parts of the building envelope, especially in relation to occupant safety and flying debris. We felt that meeting this criteria was essential.”
Shock-tube testing involves 1.5 lbs of C-4 explosive set off in a tube 60 feet away from the outside of a wall. It tests to see if any parts of the cladding or debris are blown through the wall, compromising occupant safety.
