Im confused.  No change there then.

OK, in the old days if I want to insulate an attic it was easy - just a layer of rockwool.

Then people say kingspan / cellotex are the bees knees.

Then Im told that triIso9 etc are brilliant and easy and better.  But I have to be carefull about condensation.

Then  I read this http://www.greenbuildingforum.co.uk/forum/index2.php?DATEIN=tpc_wlpssdlpg_114280...
(which takes ages)

Soooo

What do I put in the roof and in what order and do I seal it or not?

Do I put aluminium foil on the tile side or the attic side of rockwool ?  (Or do I go green and use thermofleece?) and what about ventillation ?

Help!

JD,

the attic has been converted - but its obvious from the temperature variation that they didnt bother to insulate properly.  So Im looking at what I can do between the roof and the plasterboard.

Bloody freezing in winter, boiling in hot weather.  I havent yet ripped down the plasterboard - but Im getting itchy fingers!

Roof structure is < 200 years old - big purlin and I assume reasonable size rafters.   Theres a velux and the wall?roof is about 8" thick at the velx.

thanks JD.  I'll give that a read.

So am I right in thinking that these foil/bubble things are not so hot  

Looking at stuff there seems to be confusion between products which reflect heat and products which insulate.  TriIso9 (TriIso10 as it now is) looks to be a reflectant with a thin layer of insulation on the back.  

I hate building regs.

thanks Jerry.

Ever used Thermafleece?  Any opinion?
