DESCRIPTION
MedO S2 Wildflower Seed Mix is designed to replicate natural planting, combining species that will enhance the growth of each other as well as protecting and prolonging the life of your roof membrane. Radmat provide pre-grown sedum matting, wildflower seed mixes and more conventional plug plants varieties.
APPLICATION
Seeds need both warmth and moisture to grow and may be sown at any time of year when these conditions are met.
The appropriate Radmat Growing Medium must be installed to the specified depth allowing for settlement.
Recommended sowing rates are 2-4g/m2, a rate allows for an extended period of establishment leaving room for both fast growing grasses and slower germinating flower seeds. Avoid sowing too heavily as this can lead to overcrowding or an imbalance in the establishment: the mix is designed to work optimally at the specified rate.
FIRE PERFORMANCE
Approved Document B Fire Safety points to the DCLG document Fire Performance of Green Roofs and Walls for best practice guidance in achieving Regulation 7(2) fire compliance with a green roof. DCLG Fire Performance of Green Roofs and Walls states that the compliance requirements for achieving Broof(t4) are a growing medium layer of a minimum 80mm and an organic content of not more than 50% (https://www.gov.uk/government/publications/fire-performance-of-green-roofs-and-walls). In addition, The Green Roof Organisation (GRO) Code of Best Practice, also recommends fire breaks consisting of 50mm deep 20/40mm rounded ballast are used at perimeters and penetrations. Gravel fire/vegetation breaks should be 500mm wide where they abut habitable space but can be reduced to 300mm in some circumstances. Key to ensuring ongoing fire performance of a green roof, and the plant performance, is maintenance as some plants will die back, others will shed leaves naturally during their lifecycle and invasive species will try to take hold. These factors all create additional organic matter that could poses a fire spread risk on the roof therefore unwanted organic matter should be removed as part of the maintenance program.
