OK now I'm home and I've got the plans. Originally the plans were submitted and with the revisions by bulding control it was as follows
- new stud wall between living area and storage. 75x50 sw stud wall with Rockwool acoustic insulation --(as Phil suggested). New front wall with windows - External skin 100 x50 studding constructed 25-50mm from inside vapour barrier on the warm side of insulation. Where the new cavity brickwork is installed a 85mm cavity filled with Crown Dritherm and 13mm dense plaster. -- Do I take it rockwool is not needed here then ? On the other walls 25mm to be left between inside face of existing single brickwork, then 100 x 75 sw studding with 75 mm kingspan between studs, vapour barrier (1200 visqueen) then insulation backed plasterboard 25mm. -- Will the 75mm Rockwool rwa45 be an acceptable replacement for the Kinspan? for building regs ? With 2 sheets of 12.5mm plasterboard (by default are they insulation backed ?) The connecting wall to the kitchen was 2 layers of 12.5m plasterboard with green glue in between. 75 x50 sw studs at600mm nominal centres with 75mm kingspan against 190mm turbo brickwork. --- again do away with green glue and replace the kingspan with the Rockwool ? Floor - insulation 110mm of kingspan kool therm k3 or similar. Carpet top layer -- tank121 ------------------------------------------------------------------------ tank121's Profile: http://forums.slimdevices.com/member.php?userid=17169 View this thread: http://forums.slimdevices.com/showthread.php?t=85319 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
