    rafter insulation query regarding multi-foil

    With the felt you have you will need an airgap between any insulation and said felt. No airgap is required between the multifoil and any other insulation used to back it up. You could use sound block plasterboard but i'd be dubious over the benefits when compared to normal plasterboard...

    rafter insulation query regarding multi-foil

    I would be supprised if your BCO won't accept: felt / 50mm airgap / 50mm PUR / TLX (or Tri-Iso S10 etc) / counterbattens / 12.5mm p'board. Is flanking sound a problem in your roof?

    Door into Garage from inside House

    FD30 with smoke seals and a self closer. The garage floor should either be 100mm down or sloped accordingly.

    How to tell if I got fire proof doors already installed?

    They wouldn't have put GW glazing in a non fire rated door. It sounds like you'd just be changing FDs for FDs...

    loft boarded out with electric and spiral staircase.

    It could technically be viewedas a criminal act to create an uncontrolled room in a roofspace as there is increased risk over and above those people who live on the ground and first floor. If something went wrong, the LA could take legal action against you.

    loft boarded out with electric and spiral staircase.

    They could not make you take the whole thing out if it was (is) technically correct but the problem you have is that your means of escape are now via a protected route (i.e fire sterile stair enclosure leading to the ground floor front or rear door).

    Insulation Types : Glass wool or Bubble foil stuff

    I'd create a cradle using chicken wire which you can fix to teh underside of the floor joists and put mineral wool in there. I'd avoid using kingspan type stuff.

    Basement Conversion

    Hi there. I'm trying to convert a basement into a habitable room and need to plumb a WC, WHB and shower up so that I can get them into the existing waste drainage system, which is obviously higher than they are. Can anyone advise?

    Pitched roof - hangers or bearer plate?

    Woody, It's less than 3.5m I was going for 150 x 50 SW rafters @ 400 Centres, so looks like I will be ok. I've allowed for birds mouthing the joists over the top of the bearer plate so they sit on top of it. Roof pitch is low at 15 degrees. Cheers
