Shallow pitched roof 4m square. 50x75 rafters topped with breathable membrane. Need is for some form of between-rafter insulation against heat loss BUT ALSO against noise from my Hi Fi. Whatever is used will be covered with 12.5mm plasterboards and artex skim. Presumably light rafters will impose a weight consideration and I would prefer to avoid Soundbloc plasterboard. Roof slopes from 2 up to 3.2 metres and a suspended ceiling is not an option. Ideas please.

Celotex or other similar board based insulation is ideal but you will need to insulate both between and under your rafters to achieve the required U-value to meet current BRegs requirements as you only have 75mm rafters and you need to leave 50mm ventilation in most cases.

Roll insulation is good for keeping sounds out (and noise from your hi-fi in
) - try Knauf or Rockwool. Build Center stock them, my local is Wolverhamption but their a national merchant and they have a full range of insulation: www.buildcenter.co.uk. They sell Celotex too and if you ask the staff they'll be able to tell you which ones are good for keeping noise out and in!!! Ali
