Adding fire-retardant or fire-extinguishing properties to perlite

Hi,

I dress up a wall using reclaimed wood cladding (see attached picture). The masonry wall is made of brick and plaster with fiberglass insulation.

For acoustic reasons, I will fill the cavities between the wood cladding and the wall with perlite (https://en.m.wikipedia.org/wiki/Perlite)

 

Is there something I could mix with perlite to gain fire-extinguishing or fire-retardant properties? I imagine some powder releasing CO2, azote, or capturing O2 if the cladding catches fire.

I live in France, so certain compounds are baned (notably borax and boric acid). I know potassium bicarbonate is a good source of CO2, but I don't know if this would cover my needs.  

FWIW, according to the city counselor, there are no fire regulations regarding my particular use case.

 

Regards,

Sylvain Leroux

Timber fires are classified as class A, Carbon dioxide is not suitable for class A fires.

I wasn't aware of that.

I would suggest having interlinked smoke alarms to warn you well before the timber catches fire.

I planned to install smoke detectors anyway. I don't understand what are *interlinked* smoke alarms though. I will do some research in that area.

If you feel the need you could buy a fire extinguisher, but do learn how to use it before you need to use it.

That makes sense. Thanks for your reply,

Sylvain Leroux
