Boughton EX 2

EX 2

Boughton Extensive Green Roof Substrate 2 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.

Applications & Installation

Boughton Extensive 2 mix with its higher organic matter content can be used where there is no ongoing irrigation available. Ideally it should be laid at a minimum of 80mm and is designed for sedum dominated schemes.

Boughton EX2 Green Roof Substrate meets and exceeds all present G.R.O guidelines. The depth of substrate is determined by the planting scheme and the weight loading capability of the roof which must be assessed by a qualified structural engineer. Our substrates can be delivered in any required format. This includes 25ltr and IBC Bulk bags. Or loose tipped as required
