Cold Smoke air transfer grilles?


Recommended Posts

Hi I have a server room on the ground floor at the bottom of the stairs (two storey office) means of escape. Currently the door has a two metal grilles with nothing in between (just the hole 150mm x 150mm) no intumescent etc. Is there a cold smoke type of grille on the market? Many thanks in advance.

Hi Eric 
you could use our fire rated intumescent air transfer grill which is available in the size of your hole (150x150cm).
I hope this helps.

Hi Rahel,

Yes thanks for that I have used your products in the past for this and was looking for something that specifically controls cold smoke?

Many thanks

You'd need a combined fire & smoke damper - these are usually powered and linked to a fire detection & alarm system.

For example you fit this to the door or doors:

Then link them to this control & monitoring system:

Which in turn is linked to your fire alarm system.

All vastly expensive hence rare to see.
