Flat roof insulation solutions

Flat roofs for energy efficient buildings, designed with safety in mind

The requirements for flat roof specification are changing. Already buildings must deliver higher standards of energy efficiency, to comply with Part L Building Regulations and fire safety regulations have also become stricter in recent years. Meanwhile, flat roofs are becoming more functional. They are now spaces for storage, recreation, and energy generation using photovoltaic (PV) panels and that comes with additional fire risk. An estimated average of 29 fires per GW of ​PV capacity occur each year,* so fire safety is an essential part of your specification.

Knauf Insulation offers non-combustible** roof insulation for both cold and warm flat roof applications, including built-up metal roofs. In addition to meeting fire safety requirements, our products also deliver thermal and acoustic performance, supporting energy efficiency and occupant comfort.

Our Technical Services team are here to guide you through every step of the process.
