Boughton SemIN 1

Boughton Semi-Intensive Green Roof Substrate 1 has a higher amount of organic matter compared to conventional extensive green roof substrates.

The mixture is very effective at retaining moisture and releasing it slowly. This means that the mixture is suited to projects where more intensive planting is required and weight loading is less of an issue.
