 Blast
Explosion Vents and Rupture Panels

Explosion Vents and Blow out panels are safety devices which are used to safely convey the explosive effects of a blast within a building to atmosphere, relieving pressure to protect buildings, equipment and people.

Explosion Vents 

Explosion Vents are designed to allow free passage of air during normal operation but in the event of a blast situation to safely convey the explosion outside the building.  Architectural Armour manufacture heavy duty welded steel vents which will remain intact and avoid injury to persons or property from flying debris in bespoke sizes to suit wall or door applications.

Rupture Panels 

Rupture panels, also known as Blow Out Panels, Frangible Explosion Panels and Explosion Relief Panels.

The frame is secured into the fabric of the building with the panel which is made from a special lightweight GRP faced insulated material held into the frame with fracture clip releases or explosion bolts.  At the pre determined blast pressure the explosion bolts give way and release the panel.

Fixed Panels 

These can be single or multiple panes and are discharged into a safe area or may be retained in a blast vent cage.

Hinged Panels 

Where it’s not possible to use a fixed panel the frames can be configured to be hinged casement units within a frame.  The most popular is a top hung casement, here the main frame is secured to the structure with a hinged casement hung with heavy duty hinges which opens to allow venting to atmosphere in the event of a blast.
