BauderEXTENSIVE LIGHTWEIGHTsedum

This is our lightest weight all-in-one system available. It comprises a mature sedum on 20 mm of extensive substrate and incorporates 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.

BauderEXTENSIVE LIGHTWEIGHTsedum achieves a CCPI mark which recognises that any claims made about it have been independently assessed across 11 clauses, providing greater clarity by offering improved product information. This gives specifiers confidence in the knowledge that they will have unambiguous information when deciding which of our systems is best for their new build or refurbishment project.

When to specify

This integrated cost-effective system is suitable for both new build construction and retrofit refurbishment projects and ideal for projects where weight and height of the build up is a primary consideration.

The vegetation blankets deliver instant greening of a roof so meet the need for a fully vegetated aesthetic finish compared to a seeded or plug planted roof that requires an establishment period.
