Boughton EX 2

Boughton EX2 Extensive Green Roof Substrate 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.    

The substrate is also suitable as a Semi Intensive substrate due to its relatively low hydraulic conductivity, making it perfect for areas prone to high levels of rainfall.
