Smart systems for green and utility roofs

Hydrophilic mineral wool panels for use as a substrate substitute on extensive green roofs where only minimal roof loads are possible, and on medium and steep pitched roofs where it is not possible to install a substrate due to a danger of it sliding off. These panels can also be used as an additional water buffering layer for extensive green roofs.
