Could anyone enlighten me on the purpose of "draft curtains" where mentioned in NFPA 409 (Standard on Aircraft Hangars)?
In particular in the context of sprinkler protection; paragraph A.5.17.3 clearly states that the reason for limiting a draft curtain area to 7,500 sqft (697 m2) is to improve detection and sprinkler response times...."
Am I right to assume that the intention is to prevent heat from a fire event from being distributed away from sprinklers above?
Would I also be right to say the same thing would apply to smoke from a fire (in respect to fire detection)?
Many thanks in advance.
