Hi, are there any experts on f30 compliant doors for building regulations. I’ve just been thrown a bit of a curved ball.
I am adding a kitchen extension and converting a loft. Because the loft conversion adds another floor, the doors leading to the hall need to be F30 compliant.
We have planned to re-use the 1930s original doors as they are solid doors which are all between 45 and 48mm deep. However, they do have 3 panels at the top and bottom of the doors which are not so deep.
When we agreed the building plans, we spoke to the building control company and they agreed these doors complied (they had a site visit)
I got an email from building control , yesterday evening, saying..... this is usually okay if the existing doors are solid oak doors that fit in their frame well, have no cracks or damages and have no hollow panels or glass. I did see the existing doors and it appears they are hollow panelled doors, these are deemed unacceptable when it comes to installing a loft conversion and will need replacing with FD30 doors,...
I can’t confirm if they are oak, but they are solid wood. Does the “hollow” refer to the panels? The builder will be putting in new door-frames and will ensure they fit tightly. Did they ven make hollow doors in the 1930s?
Is there anything I can do to the original doors to make them compliant? We had already agreed to add 3 special hinges and will have a fire detection system in every room.
I really want to keep the old doors! It’s not about saving money and I know there are decentish F30 doors about (although they are not solid wood)
Is anyone aware of 1920s/1930s style solid oak f30 doors?
