Guest Terry Posted September 30 Report Share Posted September 30 Hi, On an FD120s fire door is a white material strip on closing/hinge side of leaf. The seal is not enclosed in plastic. Would this be intumescent? There are intumescent seals (in pvc casing) on frame along with batwing seals. I was just wondering could this be some kind of acoustic material but why is it on show where it could get damaged. Quote Link to comment Share on other sites More sharing options...
AnthonyB Posted September 30 Report Share Posted September 30 A picture would be more use - could be for noise, sounds unlikely part of the fire protection - perhaps it was added after installation as the door slam was found to be too loud.
