Product Description

Blast and Ballistic Periscope Vents and Ducting can be used in numerous applications, ranging from military to commercial offices.


The product is most commonly used to transfer a blast throughout a building to the outside of the premesis.


The product is bespoke and can accomodate numerous blast pressures. Please get in touch to discuss your specific project requirements.


The offset design of the periscope vent affords privacy and security in removing direct line of sight through the vent.


Advantages

This product can be incorporated as part of a wider package to include Blast and Ballistic Louvres, vents and glass to provide a holistic product for a variety of uses.


This is commonly used in data centres where a blast may initiate in a room and needs to be vented through ducting and finally through a blast louvre.

Frequently Asked Questions

  • Why do I need a Periscope Vent?

    Periscope Vents are used to channel blast overpressures from the internal area to the external void outside of the building where a direct line of sight is not available or is preferred.


    It also adds a layer of security by removing a direct line of sight into the building.

  • Why is blast ducting necessary?

    Blast ducting is necessary in some instances because the blast may occur inside of the building which is not adjacent to an external wall. It is therefore important to channel the pressure safely through the building to the point of exit.

  • How is ducting made?

    Ducting is normally made in steel, either fabricated, folded or welded in detail, but always using material commensurate with the relevant blast load.
