They used ISO super 9 style foil/fleece insulation in a loft conversion
on DIY SOS last week.
It appeared to be stretched over the loft rafters leaving 50mm-ish gap
behind, Then battens (38mm looked like) nailed through it onto the
rafters, and plasterboard over the battens. Thus leaving suitable air
gaps etc, but where it's squashed by the battens the insulation must be
poor.
But you get a much thinner roof than with celotex. Seeing a neighbours
loft conversion where you could hardly stand up a while ago, made me
think.
And what about using it in normal roofs. If it's evquivalant to 75mm
celotex, my extension roof design could be a lot thinner.
Is this stuff proven, and would the BCO pass it ?

Hi,

Long discussion of it he

http://www.greenbuildingforum.co.uk/forum/index.php?DATEIN=tpc_wlpssdlpg_1142805843

Looking at p21(!) it appears the super 10 stuff has a TRADA cert for
roof construction, so that /should/ keep BCO happy, though it would be
well worth asking.

cheers,
Pete.
