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.
Insulation pitched roof space.
This means insulating between or below the sloping beams that form the construction and support a sloping roof.
Kingspan with a warm roof the usual process is to split the insulation into two layers.
Look for water stains on the roof sheathing or damp or moldy spots on attic joists and existing insulation as a clue to where leaks might be.

For new pitched roof buildings it is common to opt for the warm roof construction method and it is also suitable to install warm roof insulation when re roofing an existing detached building.
If vents need to be added first this can increase the overall cost of this project.
