For over 50 years, Optigrun has been at the forefront of roof greening innovation, helping transform urban environments across Europe. Through industry-leading green roof systems, expert technical support, and dedicated customer service, we work with architects and contractors to create greener cities, enhance biodiversity, and deliver lasting sustainability benefits.
Beyond standard green roof build-ups, Optigrun offers an extensive portfolio of specialist systems designed to meet the demands of even the most complex and ambitious projects.
BIOSOLAR ROOFS
There are many advantages to combining photovoltaics and a green roof:
Evaporative cooling of vegetation leads to an increase in the efficiency of the photovoltaic system. At the same time, the green roof makes an important contribution to preserving the natural water balance and increasing biodiversity.
The load-supported solar mounting frames from Optigrun are fixed in position and protected from wind suction by the weight of the green roof structure. No roof penetration is necessary for the installation.
PITCHED GREEN ROOFS
Sloped green roofs require special attention right from the initial planning phase. Roof pitch, roof design, roof structures, loading and the required shear resistance measures all need to be adjusted for the desired vegetation.
Optigrun offer a variety of specialised green roof systems specifically designed for pitched roofs. Our anti slip systems can be used on pitches up to 45 degrees.
BLUE ROOFS – WATER RETENTION
The issues of water attenuation and SUDS are now an important consideration for many building projects.
Green roofs are already known for their ability to attenuate water, but this can now be enhanced with blue roof technology.
The key to a successful blue roof is design, both in terms of the roof construction and the drainage outflow parameters for the site. Optigrun offers professional planning support and will prepare the necessary calculations for your construction project.
