Flat roofs are a less common sight in the UK owing to their typically higher maintenance requirements when compared to other forms of roof construction, although they can be a versatile form of roof construction.

It can be difficult to provide a very high level of thermal performance in these roof types, whether you’re looking to insulate at joist level for a cold roof (where joist depth can be an issue) or above the roof deck (where overall roof height may need to be considered) if a warm roof construction is desired.

Celotex 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 flat roofs whether you’re looking to insulate at joist level or above the roof deck in your flat roof construction.
