I need to know if it is better to add the foil insulation layer on top of the top up insulation layer I have added to my loft floor OR should I add the foil insulation to my loft ceiling after insulating loft ceiling????
Basically, foil over topup on loft floor
or
add foil to insulated loft ceiling???
