Modern roofs need to do more than maintain energy efficiency. They are also spaces for energy generation, storage and socialising. A futureproof flat roof must support energy efficiency, solar installations, and increased load, while ensuring safety and comfort for occupants, for the life of the building.
Photovoltaic (PV) or 'solar' panel use is growing– partly due to initiatives like the European Commission’s REPowerEU Plan and the Energy Performance of Buildings Directive.
But increased functionality comes with increased fire risk.
Solar panels on a roof mean a greater chance of ignition and if that happens, they can also accelerate the spread of the fire.
Rooftop solar panel use is expected to outpace large-scale energy plants by 2028 so a solar-ready, safe, futureproof flat roof is an essential part of your design.
What to look for in your insulation
- Non-combustibility
Our unfaced Rock Mineral Wool products are non-combustible with the best possible Euroclass A1 reaction to fire classification, so they will not contribute to the spread of a fire, should it occur.
- Thermal and acoustic comfort
Our insulation delivers reliable thermal and acoustic performance, creating a comfortable indoor environment.
- Durability and longevity
Our products with high compressive strength allow a roof to withstand additional loads, from solar panels and environmental factors. They are designed to last for the expected lifetime of the average building, reducing the likelihood of costly remediation work later.
Our Rock Mineral Wool for flat roofs delivers against all these essential performance criteria.
Don’t over-specify.

Our flat roof solutions fall into three categories:
Standard – Suitable for simple flat roofs that deliver energy efficiency, with no access requirements.
Solar-ready – With enhanced mechanical strength, to support solar panel installations and associated maintenance requirements.
Solar-plus – With maximum mechanical strength, suitable for flat roofs with solar panels and other functional requirements. Our solar-plus solutions also include options for green roof systems.
All our flat roof solutions use non-combustible insulation that delivers reliable thermal and acoustic performance, for the life of the building.
