The European Commission requires us to reduce energy consumption in buildings and prepare them for photovoltaic panels.
The new European Directive – Directive (EU) 2024/1275 – states that new buildings must achieve “zero emissions.” Industrial buildings must also be “solar ready.” Materials used must be durable, thermally safe, and fire-resistant.
Roofs with photovoltaic panels have much stricter requirements, which is why careful selection of mineral wool insulation is essential. Photovoltaic panels generate high temperatures, while cables and inverters create additional risk zones.
A roof with photovoltaic panels involves partial shading, heat accumulation, electrical hazards, and vibrations. Ordinary materials are not sufficient.
FIBRANgeo-BP and Rock7 stone wool boards, offering the highest point load capacity, are high-performance insulation boards specifically recommended for photovoltaic roofs. They are non-combustible (Euroclass A1) and fire-resistant, making them the ideal choice for these demanding applications.

FIBRANskin membranes offer maximum efficiency with minimal thickness.
The trapezoid elements FIBRANgeo SI-080 TRAPEZOID stonewool have been specially developed for installation in the channels (valleys) of the trapezoid metal roof or panel sheets, thus providing extra thermal insulation and increased mechanical integrity of the insulation system. The elements are offered in standard dimensions or cut-to-measure according to project.
The FIBRANgeo INCLINE stonewool boards are prepared in the factory according to the drawings of the roof area, taking into consideration water drainage and plan details. The boards arrive on site pre-cut with the desired inclination, each with clear lettering for easy installation.
