PermaSEAL Sedum Roof Trays provide a quick and simple way to create an attractive, long-lasting sedum green roof. The modular tray system is designed for straightforward installation on suitable flat roofs, making it ideal for extensions, sheds, garden offices, bin stores, bike stores and other outdoor structures.

Each all-in-one tray combines drainage, water storage and healthy sedum grown from seed. The trays interlock to provide instant greening and are easy to handle, transport and position, including in harder-to-reach areas.

The system is suitable for DIYers and professionals alike, offering an accessible way to create a low-maintenance green roof with established sedum coverage. The trays can also be removed if access to the waterproofing layer is required.

The Permagard Green Roof Kit contains the core components needed to create the foundation of a healthy living roof for homes, gardens, offices and outdoor structures. It is designed for suitable flat or low-pitched roofs under 9.5°, providing a practical starting point for DIY green roof projects.

The kit includes a root barrier membrane, PermaSEAL PRO 8 Green Roof Drainage Membrane and PermaSEAL Double Sided Jointing Tape. These components help protect the roof structure, manage drainage and support the build-up required for a successful green roof.

This kit is especially well suited to sheds, extensions, garages, conservatories, cycle shelters and similar structures. It offers a simple way to begin a green roof installation while still allowing customers to add the growing medium, vegetation and accessories best suited to their project.

PermaSEAL PRO 20P is a high-quality green roof drainage and storage membrane manufactured from HDPE. It acts as an all-in-one drainage layer and high-volume water storage membrane, making it suitable for extensive and intensive green roof systems on homes, sheds, garages and larger commercial projects.

The 20mm cavities help store water to support healthy vegetation, while the perforated design allows excess water to drain away. This helps prevent waterlogging and protects the roots of sedum, grass and other vegetation.

PermaSEAL PRO 20P also features an integrated geotextile fabric bonded to the membrane. This helps filter out fines and other particles while saving time during installation compared with using a separate loose geotextile layer.

PermaSEAL PRO 60P is a high-performance intensive green roof drainage and water storage membrane designed for demanding green roof and hard-landscaping applications. Its 60mm deep perforated cavities provide impressive water storage capacity, making it suitable for roof gardens, intensive green roofs and areas designed to support more substantial vegetation.

The membrane can be used in a wide range of horizontal applications, including commercial and residential roofs, balconies, terraces, inverted roofs, underground car parks, walkable decks and driveable areas. It is suitable for projects involving plants, grasses, shrubs and trees, as well as paving and hard-landscaping build-ups.

PermaSEAL PRO 60P offers high drainage capacity, water retention and compressive strength, making it a strong option for larger projects, very low roof slopes or longer drainage lengths. It forms part of the wider PermaSEAL PRO green roof range, with technical support available from Permagard for project suitability and product selection.
