i need to insulate my vaulted ceiling for building regs ,, the plans say 5 inch of insulation in rafters and 1 inch over top,, fitting in the 5 inch between the rafters is easy but,,,, what i need to know is what the best or easy way to cover it all ,,,,,,IE 1 inch of insulation and then foiled plaster board or the insulation fixed to the plaster board just seems difficult to screw to the rafters and noggins ??? any advice

That's a standard specification and shouldn't be that difficult to fix. In fact it's normal to specify 40 or 50mm. Just use long fixings.
thanks john but what would be the best 1 inch insulation over laid and then ordanary plaster board,,,, or plaster board with the insulation attached to it

Go for the cheapest. Prolly insulation and then board. Don't bother with foil back.
