This is a simple green roof kit that can be installed in a day. It comprises a root barrier, water retention blanket and sedum matting.
Enviromat pitched green roof kit is suitable for living green roofs with a gentle slope between 3 and 20 degrees. If the roof has a steeper or shallower pitch, Harrowden Turf provides advice on specification.
The waterproofing on the roof needs to be intact and in good condition and the building needs to be able to support a load of 60g per square metre with extra for snow loading and / or anyone standing on the roof. The edging for the roof is not included in the kit.
The Enviromat pitched green roof kit contains:
• Polyethene root barrier - (per square metre)
To protect your waterproofing against damage from roots and boots. Water retention matting.
• A fleecy blanket - (per square metre)
Specially engineered to hold 9 litres of water per square metre. Water retention fleece is essential to support the plants through periods of drought and is far less weighty than the alternative of using a deep layer of growing medium.
• Enviromat sedum matting in - (per square metre)
Enviromat is a blanket of low growing sedum plants with at least 95% plant coverage. Seven species of sedum plants are seeded in a random fashion into the mats and then grown on for at least 12 months to create a wonderful mix of ever changing textures, colours and floral displays. Enviromat contains all the growing medium needed to sustain sedum plants held securely in place by a strong, non-degradable mesh that is unique to our brand.
• Instruction Guide: a step by step illustrated guide to creating a living sedum roof.
