Langley Waterproofing Green Roof System are a tried and tested solution in the construction of an ecologically and technically sound rooftop. The past decade has seen increasing interest in the design of roof areas that interact harmoniously with their surroundings. Green roofs provide a positive effect on the environment and can provide areas of recreation for building owners. There are also the technical advantages of noise and air temperature reduction, protection of the roof against UV and climatic extremes and the obvious minimising of the possibility of mechanical damage. All this, combined with the availability of today’s purpose designed products, with a track record in waterproofing and root protection, now make the green roof option a viable interesting choice for architects and specifiers alike.
