Daniels locksmiths Posted February 22, 2021 Report Posted February 22, 2021 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 Quote
Neil ashdown Posted February 25, 2021 Report Posted February 25, 2021 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.

JMFORTUNE Posted November 30, 2021 Report Posted November 30, 2021 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. Quote
Neil ashdown Posted December 9, 2021 Report Posted December 9, 2021 (edited) 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.
