Hi All,
When insulating a loft. I know that building regs say that there should be 270mm of insulation up there.
My question is this: If putting insulation in the rafters below the roof as well, would I still need 270mm of insulation under the floor or is the 270mm of insulation usually shared between putting it in the rafters under the roof and in between the joists with flooring down on top of them?
I'm a little confused and need some clarification.
Regards,
Brett Rogers
