GREEN ROOFS Zink 801927 www.almhm.co.uk 01992 Copper Stainless Sundolitt’s XPS insulation was specified for Northumberland National Park’s new National Landscape Discovery Centre. Known as The Sill, this visitor attraction, near Hexham is inspiring people of all ages to explore the landscape, history, culture and heritage of Northumberland. XPS 300 grade was specified by JDDK architects for the living roof, which is fully accessible with a walkway and platforms, providing a vantage point across one of the UK’s most magnificent landscapes, and the UNESCO World Heritage Site of Hadrian’s Wall. In total 1,900m² was installed, built up to a thickness of 270mm with flower-rich native Whin Grassland planted on top. Sundolitt’s XPS material was chosen as a cost-effective solution that could withstand the heavy loads of soil and planting, as well as constant footfall on the roof. XPS is reportedly also water-resistant and not affected by water, allowing the green roof to thrive. The creation of the living roof with Whin Grassland habitats is a unique feature of the visitor centre. The soil was made up especially for this project and based on soils found in abandoned whinstone quarries locally. Species-rich, small slow-growing grasses and flowers were sown a few months prior to the centre opening in July, and although the vegetation will initially appear sparse, it will reportedly thrive on its XPS base with minimal maintenance. www.sundolitt.co.uk Alumasc on target for WWII bunker The former decoy bunker is now a holiday home Discovery Centre green roof thrives Originally built in 1941 as a special decoy target for German bombers, the decoy bunker is tucked away in the rolling hillsides of Monmouthshire and has been fully restored as a holiday home. As the bunker had to blend directly into the hillside, a highlydurable waterproofing system was needed to provide full protection against water travelling down from the surrounding landscape, as well as providing a ‘camouflage effect’. Alumasc’s registered contractors, Span Roofing, installed Blackdown green roof drainage layers, intensive substrate, and washed pebble ballast to finish the green roof. A Derbigum black antiroot built-up system sits below the green roof and reportedly provides a ‘highly reliable’ waterproofing solution with ‘maximum peace of mind’ for the future, as the Derbigum system holds 40-year durability certification with the British Board of Agrément.
