A series of Flag UK green roofs have been incorporated into a nine apartment development in Tavistock. They are said to be making a positive contribution to the environment in an area of outstanding natural beauty as well as providing an efficient drainage.
The developer's decision to use a green roof system was welcomed by local planners as the area of garden taken away by the development footprint matched the area of the roof. In an area of the country where rainfall can be sudden and intense the green roof will reduce water run-off by as much as 60% says the company. The system contains a single ply membrane, which was primed with a vapour barrier and 95mm of insulation.
A green roof on a log cabin in Tighnadroma, Tayside, has been created with the use of Flagon EP/PR TPO membrane from Flag.
The original waterproofing needed replacing so the deck was stripped back and renewed in parts. Installed on the top of the deck was a vapour barrier with 100mm Insulation board and timber edges around the roof perimeter.
Flag TPO membrane was then installed, followed by a drainage mat and edge retainers to hold soil in place. The roof was completed with a layer of locally sourced turf.
Structural movement was required to repair the roof, which the Flagon membrane was flexible enough to accommodate.
Construction of a 500 hectare paper manufacturing plant in Wales involved the use of Flagon SR pvc single ply membranes from Flag UK. Some 90,000m of Flagon pvc membrane was installed on the roof.
The roof construction comprises of profiled steel decking fixed to the metal frame with a polyethylene overlay and 130mm layer of insulation. Flagon SR polyester reinforced single ply membrane was then mechanically fixed, with SFS Intec telescopic and austenitic stainless steel fasteners used to secure the insulation.
At the Ikea job site in Piacenza, Italy, Flag are currently installed some 100,000m? of TPO membrane.
The product is a synthetic membrane made from ethylene propylene rubber modified polyolefin. Flagon waterproof liners, produced by coextrusion or spreading, can be homogeneous, reinforced with polyester mesh or stabilised with glass gauze. They can also be coupled with geo-textiles, making them suitable for fully adhered laying or on a substrate in chemically incompatible material.
Designed to emphasise the importance of sustainability in urban living, a final year student at Glasgow School of Art has made a roof garden using Flag TPO membrane.
In the 16m garden student Beth Hamer created a grid of 25 squares, each relating to the land map of Scotland.
The green roof membrane comprised a TPO membrane covered with a protection mat, Optigreem drainage board and felter fleece top.
