Description


DERBISOLAR® is a waterproofi ng membrane with integrated fl exible photovoltaic a-Si cells which convert sunlight into electricity.
The DERBISOLAR system is suitable for:
- Non-accessible (or only accessible for maintenance), fl at or sloped (min. 3%)
roofs, with no water stagnation zones.
- New constructions
- Renovation of roofs with new roofi ng or compatible membranes.
DERBISOLAR consist of a bitumen waterproofing membrane DERBISOLAR BASE from
the DERBIGUM® product range and photovoltaic laminates PVL-68, PVL-136 or PVL-
144 from UNISOLAR®.
