Product Overview of BlastWall

The Invisible BlastWall is a unique all-fiberglass blast fence with the structural strength to withstand jet takeoff blast and remain invisible to radar and radio transmissions. It is engineered to deflect a blast of 160 km/h at a safety factor of 1.5:1, yet has sufficient frangibility to collapse upon impact without major damage to aircraft or the Invisible BlastWall.

All the components of the Invisible BlastWall, including the nuts and bolts, are made from pultruded or molded fiberglass to create a lightweight and durable structure with no metal parts. Pigment and UV stabilizers are incorporated into the fiberglass resin to make it corrosion-resistant and maintenance free.

The Invisible BlastWall has been tested extensively by NAV Canada for non-interference performance during ground based and in-flight electronic signal emissions. It has been engineered to meet or exceed NAV Canada airside installation requirements and has been approved for installation in airports across Canada.

BlastWall Features:

» Non-conductive and non-magnetic to radar and radio frequencies.

» Engineered to withstand jet takeoff blast and associated high temperatures.

» Frangibility in the event of impact by aircraft achieved through specially engineered shear points.

» Structurally lightweight and easy to set without the need for cranes.

» No service interruption during installation.

» Fire-retardant, Class 1 flame-spreading rating 25 or less per ASTM E84.

» Pigment and UV stabilizers incorporated into the resin making it corrosion and UV resistant.

» Self-cleaning and maintenance free.

» Tested by NAV Canada for non-interference performance during ground based and in-flight electronic signal emissions.

» Meets or exceeds NAV Canada regulations for airside installation.
