Pitched roof: insulated above and between rafters

Pitched roof: insulated above and between rafters
Design and Installation

Insulating a pitched roof at rafter line – to create what is usually known as a warm roof – makes full use of the building volume by making the roof space available for occupation. Installing part of the insulation between the rafters reduces the depth of insulation required above the rafters, which reduces the load on fixings and makes installation easier.
