Pitched roof: insulated between and below 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 beneath the rafters, which minimises the loss of headroom.
