Pitched roofs are a common sight in the UK owing to their versatility and typical low maintenance requirements when compared to other forms of roof construction. Another key advantage of specifying a pitched roof is the ability to provide a very high level of thermal performance in these roof types, whether you’re looking to insulate at joist (ceiling) level for a cold pitched roof or at rafter level if a living area within a warm roof construction is desired.

Saint-Gobain Insulation UK manufacture and supply glass mineral wool slabs and rolls along with rigid Polyisocyanurate (PIR) boards that can be considered suitable for a wide range of applications across pitched roofs whether you’re looking to insulate at joist level or at rafter level in your pitched roof construction.
