July 6, 20206 yr comment_17450 Hello, Is running a kitchen extractor fan duct from the flat below along the interstitial space between ceiling and floor above a fire risk? Also the flexible extractor duct is squeezed through a narrow opening at a 90 degree angle. Would really appreciate an informed opinion. Thanks. Report
