Canopia ST Biodiverse Plug and Seed System - INVERTED Roof

The Canopia ST Biodiverse Plug and Seed System - INVERTED Roof is designed for inverted roofing applications and provides a biodiverse planting scheme with undulating substrate depths to encourage a diverse range of flora and fauna using wildflower /sedum /grass plug plants and seed mix to allow greater flexibility of design. It is suitable for use on specified Icopal root-resistant flat roof waterproofing systems.

  • The substrate depth provides added ballast weight for inverted roofing applications

  • Using plug plants and a seed mix allows flexibility in design and species layout

  • Visually attractive mix of wildflower /grass species which creates great aesthetics

  • The seed mix is sown between the plug plants to promote further beneficial plant colonisation

  • The undulating substrate depth of the system encourages a greater diversity of flora and fauna to develop over time

Canopia Drainage Board 20 is used as a water reservoir and drainage board.

Canopia Fliter Fleece 105 is used as a filter fleece to reduce the amount of fines particles reaching the drainage layer, and as a separation layer betwen pebble borders and the growing substrate.

Canopia Extensive Substrate is blended growing medium designed to provide a balance of water retention and drainage to create the ideal root environment for succesful plant growth.

Canopia Biodiverse Plug Plants are a mixture of wildflowers and grasses supplied as small plugs growing in trays used for planting up green roofs.

Canopia Wildflower Seed Mix is used for sowing onto green roofs to provide a selection of different wildflower species.

Canopia Washed Pebbles (20-40mm) are natural aggregates used to improve drainage flow rates around green roof details and create vegetation free borders and firebreaks.
