Veg Tech, founded in 1987 in Vislanda, Sweden, has helped its customers to create greener and more natural environments for over 30 years. The company grows, develops and delivers multi-purpose vegetation systems, which help to reduce storm water runoff, improve water quality and support biodiversity. The vegetation is produced in Småland, Sweden.
Veg Tech sedum-moss green roof structure is generally particularly well suited for sites where a thicker growing medium cannot be installed due to its weight. Generally, a VT-Filt felt mat and a Xerodrän drainage layer should be installed under the vegetation blanket. This structure weighs approximately 50 kg/m2 and is roughly 55 mm in height. The structure is suitable for roof pitches 1:2...1:50.
There must always be a waterproofing membrane with a root barrier underneath the green roof.
