XF 301 Sedum Blanket Extensive Green Roof System

When to specify...

This is our lightest weight all-in-one system available. It comprises mature sedum on 20mm of extensive substrate and incorporating a multifunctional water retention and filter layer. The system is suitable for both new build construction and retrofit refurbishment projects. In most instances an additional drainage layer (BauderGREEN SDF) is not required though on roofs up to 2° or in areas of high rainfall, its inclusion may be necessary.

Key features
