    Hi Folks

    I live in a timber frame Semi Detached house, There is not a concrete wall between myself and my neighbour there is 2 sheets of plastarboard, a stud, 2 sheets of ply type wood, a stud and 2 sheets of plastarboard. Sandwiched in between this is loads of fibreglass. Standard build my architect tells me.... I am happy but dubious!

    The thing is i was up in the attic and notice that there is no fibreglass sandwich there. Is this normal? If you catch my drift. ie is the plasterboard a sufficent fireseal. Is there anywhere i can check on timber sprcification to make sure this is safe.

    PS:Is there somewhere i can learn more about timber frame specifications.

    Joey, it looks like standard acceptable alright.
    The plasterboard - two layers gives you fire protection, and the fibreglass gives you sound insulation - albeit if installed correctly.
    If you get a chance, get hold of the most uptodate version of the Homebond manual, and you'll find an excellent section on Timber frame construction.
    Pity the butchers ahem carpenters they send out on site to erect have never heard of Homebond.

    In relation to fire, double slabbing on both sides is acceptable provided its carried right up to the underside fo the roof and sealed.
    See page 4 of this: http://www.gypsum.ie/architects/manuals/documents/3.7TimberStudPartitionsJan09.pdf. The partywall needs to provide 60 minutes fire resistance.

    AFAIK, if the attic space isn't habitable, there is no requirement for fibreglass within the wall for sound.

    Lads I appreciate you coming back. I suspected so on the fibreglass it sounds good to hear it. I have a slight gap of about 12 inches left bear so i will double slab and scrim it myself.

    As regards fore protection. It does not look to be sealed as such at the top. As in no special sealer. My attic is about 12ft high so you can bet I am not climbing up there but interesting.

    I figure if there is a fire on my side the attic will be my last worry. If there is a fire on my neighbours side(Perish the thought) there is always a good solicitor looking for a claims case :D

    Long term I would love to coonvert the attic but not to sure if its easy done. So would have to fill this with solid insulation i guess,


    ps: the house is guaranteed by Premier bond! If you think home bond is interesting just wait till you deal with these. Nothing is entertained under 650 euro!
