Guest ChrisMcC Posted October 8, 2016 Report Share Posted October 8, 2016 Not sure if you can help but I need a quick question answering for work. What is the maximum gap allowed between and intumescent strip and a door keep? Quote Link to comment Share on other sites More sharing options...
Tom Sutton Posted October 8, 2016 Report Share Posted October 8, 2016 Three millimeters plus or minus one millimeter between the door edge and the frame. The intumescent strip should be fitted into a groove cut in the door edge or the door frame and be flush. However if smoke seals are required they should seal the gap between the door and frame, to prevent cold smoke from passing through. Quote Link to comment Share on other sites More sharing options...
Guest Sped Posted April 3, 2017 Report Share Posted April 3, 2017 when measuring gaps between doors is it measured from the smoke seal to the frame? I. E. Putting a 3 mm packer in if it holds in place it passes? Quote Link to comment Share on other sites More sharing options...
AnthonyB Posted April 5, 2017 Report Share Posted April 5, 2017 There should be no gap for a smoke seal otherwise it fails to perform it's job of stopping cold smoke passage prior to the activation of the intumescent seal underneath.
