IKO Polymeric has provided a biodiverse ‘brown roof’ on a new development in Craigshill, Scotland.
The 1,550m2 purpose built learning disability centre has replaced two existing facilities at Linlithgow and Blackburn. The design was closely developed with all user groups and the local authorities, and reflects a positive and inclusive vision of disability incorporating the most up-to-date guidelines for people with severe learning disabilities, challenging behaviours and sensory impairments. The energy efficient development includes an arts-and-crafts room, a music room, an IT suite, a sensory garden and the biodiverse roof.
Following a CPD carried out by IKO Polymeric at Glasgow based Chartered Architects MacMon, an IKOgreen biodiverse system was chosen for suitability. The system makes use of recycled materials e.g. crushed brick, crushed concrete etc. in the growing medium, and is intended to create a natural wasteland which can be seeded initially with selected species to create some growth. The basic design is to attract indigenous fauna and flora of all kinds and provide a habitat capable of supporting wildlife as well as enhancing the appearance.
Before installing the biodiverse roofing system, IKO Polymeric’s UK manufactured Spectraplan TPE SG120 Dark Grey single ply waterproofing membrane was installed over IKO’s self-adhesive vapour control layer and insulation. Spectraplan TPE single ply membranes are free of halogens (Chlorine, Fluorine, Bromine and Iodine), softeners, (H)CFCs and heavy metals. All single ply membranes offered by IKO Polymeric are resistant to weathering, chemical oxidation and UV radiation which ensures long term durability, a key factor in environmental sustainability.
Other elements of the IKOgreen biodiverse roofing system included Plasfeed 5+1 filtration and drainage layers, and IKO filter fleece.
