Eric90 Posted May 14 Report Share Posted May 14 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.

Rahel Lock Posted May 15 Report Share Posted May 15 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. Rahel Quote Link to comment Share on other sites More sharing options...

Many thanks Quote Link to comment Share on other sites More sharing options...
Rahel Lock Posted May 15 Report Share Posted May 15 Hi Eric ok, thanks for pointing this out again. We don't currently have any air transfer grilles that work on cold smoke. Maybe someone else here has any experience? Thanks Rahel Quote Link to comment Share on other sites More sharing options...
Mike North Posted May 15 Report Share Posted May 15 This would not stop smoke which is what is needed at the bottom of a stairwell Quote Link to comment Share on other sites More sharing options...
AnthonyB Posted May 15 Report Share Posted May 15 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: https://www.firesealsdirect.co.uk/passive-fire-protection/intumescent-grilles/fire-smoke-air-transfer-grilles/lvn20s/lorient-lvn20s-fire-smoke-resistant-air-transfer-grille-kit-200x200mm-54mm/ Then link them to this control & monitoring system: https://www.firesealsdirect.co.uk/passive-fire-protection/intumescent-grilles/talkback-damper-control-system/ Which in turn is linked to your fire alarm system. All vastly expensive hence rare to see. Quote Link to comment Share on other sites More sharing options...
