If 180mm is to be installed then 100mm board might be introduced between the rafters there has to be a minimum 25mm air gap between the insulation and the underside of the tiles or slates with an 80mm board running across the rafters.
Warm loft insulation is used on pitched roofs where you are using the loft space as a room or for storage.
