Foil Back Ceiling boards

    Hi,

    We're in the process of purchasing a house that's almost at a builders finish. We had a surveyor out and he identified that the ceiling boards on the first floor were not foil back and raised this as a major concern. He suggested that either the ceiling be taken down and started again or that foil-back boards are screwed over the existing ceiling, ensuring they are screwed into the rafters.

    I've sent this on to our solicitor for follow-up with the builder, as I know this is also against building regulations.

    How big an issue is this? And are there any other alternative options, other than the two noted above?

    Thanks

    where does it say in the building regulation that you have to use foil back slab ?

    we are one of the few country's in the world that use foil back slabs .

    Your surveyor should go back and study building Physics and not be spouting off on topics he knows nothing about .

    We are moving away from foil back slabs as they causes problems with moister build up and are not defusable in a wall of ceiling build up . Do a due point calculation on it and see what results you get on using foil back slab .

    In my opinion the builder has done you a favour .

    Not having a vapour barrier is a big issue. It will mean your insulation and roof structure over will be damp from moisture/humidity from the house, especially in winter. The consequences are that the insulation is now effective, you will get damp through into the ceiling and long term it could damage the roof structure.

    His proposed solution is appropriate for a normal house built between 1980's and late 2000's.
