FLAG UK has supplied roof waterproofing membranes since the early 60’s, and was among the green roof market innovators with its Optigreen range. With its diverse range and extensive variety of planting options, Optigreen systems have extended the scope for living roofs while at the same time enabling designers to improve thermal and acoustic performance, improve storm water attenuation, reduce CO2 emissions and increase urban biodiversity. Optigreen green roofs provide resistance to flying sparks and radiating heat and improve microclimates by cooling and humidifying the air and filtering and binding dust and other harmful materials in the process. As with all the sectors in which FLAG UK is involved, the company continues to innovate involving, for example, adapting planting to include local indigenous species.

Millions of square metres of FLAGON waterproofing are installed throughout the world each year, to meet every conceivable climatic condition. These have included the roofs of a number of Olympic stadium venues. What sets FLAG apart is its consistent emphasis on design innovation, improvement of installation techniques, contracting quality and support for designers at every stage of a project. The company’s FLAGON TPO Roofing Membrane was the first product of its type, for example, to achieve a BREEAM A+ rating.

As one of Europe’s principle manufacturers of single ply products, FLAG UK is an active member of the U.K. Single Ply Roofing Association (SPRA). Since November 2007 the company has been part of the Soprema Group.
