Guest Sylvain Leroux Posted December 7, 2021 Report Share Posted December 7, 2021 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 Quote Link to comment Share on other sites More sharing options...
green-foam Posted December 9, 2021 Report Share Posted December 9, 2021 Timber fires are classified as class A, Carbon dioxide is not suitable for class A fires. I would suggest having interlinked smoke alarms to warn you well before the timber catches fire. If you feel the need you could buy a fire extinguisher, but do learn how to use it before you need to use it. Quote Link to comment Share on other sites More sharing options...
Guest Sylvain Leroux Posted December 9, 2021 Report Share Posted December 9, 2021 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 Quote Link to comment Share on other sites More sharing options...
green-foam Posted December 9, 2021 Report Share Posted December 9, 2021 Interlinked means they are linked together, either by a cable or radio (Cable ones are cheaper) When one activates, they all sound. Example: Fire in kitchen, smoke alarm makes noise, but so does smoke alarm in bedroom Quote Link to comment Share on other sites More sharing options...
green-foam Posted December 9, 2021 Report Share Posted December 9, 2021 FYI: Fire extinguishers in Europe are divided into different categories depending on what type of fire they are designed to extinguish. Each category is assigned a letter, more information can be found on the safelincs page if you Click here Quote Link to comment Share on other sites More sharing options...
