This is where you consider the ventilation and sealing of the roof.
Introduction warm cold roofs this guidance offers guidance on the difference benefits between warm and cold roofs.
As it avoids the need for aeration of the roof construction.
There are many benefits to this type of construction including making a home more energy efficient and minimizing the thermal bridge at the eaves.
