February 22, 20215 yr comment_19391 Hi all, I’ll give you a brief background info on me. Carpenter for over 20 years and locksmith for 12 years. Past 2 years I’ve started advertising in fitting fire doors as there didn’t seem to be anyone advertising such a service local to me. I’ve now been asked the following... “We need a single swing-both-ways fire door with a glass panel for a new opening from the commercial kitchen to the bar area and ideally the door frame too. The opening is currently 900 x 1900 mm “ I seem to remember a building inspector years ago saying these hinges are no longer with in regs due to the gaps and or leading edges leave the door exposed / venerable. Could someone confirm if these hinges are allowed. I have seen two separate doors for a commercial kitchen. One to Push to enter kitchen and one to Push to leave kitchen. Thanks Report
February 25, 20215 yr comment_19423 For a double-swing-action timber-based fire door it will be necessary to use pivots instead of hinges. It will likely be necessary to use a floor=spring instead of an overhead self-closing device. Not all timber-based fire doors will be suitable for this application, so consult a specialist fire door supplier/manufacturer. And follow the installation instructions for that particular door leaf.

November 30, 20214 yr comment_22641 Hi How do I ensure that any gaps do not exceed the limits for these doors? As I have a similar canteen double action door which has large gaps on all sides due to no frame / recess to seal these. Report
December 9, 20214 yr comment_22786 If the doors are fire resisting doors, then in order to be compliant to the Standard the minimum and maximum gaps will need to be achieved. BS 8214: 2016 guidance states 2mm to 4mm at the top edges & vertical edges and the threshold gap should be to the door manufacturers installation instructions (usually 6mm to 10mm). This can be difficult to achieve for double-action doors. If the doors are required to provide 'restricted smoke spread' then the smoke seals should seal the operating gaps, including at the threshold. BS 8214 https://shop.bsigroup.com/products/timber-based-fire-door-assemblies-code-of-practice/standard Clearly, intumescent edge seals and most likely smoke seals will be required.
