I have a pair of old 1940s double doors, that are made of solid oak. They are heavy and around 42mm thick. We have got new frames with intumescent strips for them. There are two issues that I think might be picked up by my BCO (who is expecting these to comply with FD30).
1) each door has a couple of pretty small panes of glass which obviously won’t be fireproof. Could I fix that by adding some of this film into each pane: https://www.3m.co.uk/3M/en_GB/p/d/b5005059008/
2) I think double doors need a “pair maker” to be made into fire doors. Anyone know if that is the case?
Any other issues?
Thanks
