Only 145mm of Rockwool insulation comes from factory. This saves on transport. Another 70 to 190 mm of insulation is added on site to the inside of the walls. We call this passive and super passive upgrade. (Referring to the 145mm wall used by Scandinavian Homes since 1990 in Ireland)
The doors are locked in the evening of the first day of construction. 3 days later the house -shell is built with felted roof ready.
