Hi,

I hav a project that the client has specified a 4.5m height x 3.8m width double door and the door required a 2 hours fire resistance in both integrity and insulation (BS/BS EN Standard). Are there any existing door hav met those requirement above? If not, are there any laboratory in the world would provide fire test for fire door in this size?

Any advice or alternative would help.

Thanks for any assistance.

That seems a big ask. Don't know how far you've got with this but suggest talking to International Fire Consultants to ask if they know of such a product.  FD120 doors details at https://www.warringtoncertification.com/certifire/timber-door/fd120.html  and at  https://www.warringtoncertification.com/certifire/fire-doors.html suggest talking to manufacturers to what's possible.
