Before 1995 green roofs were virtually non-existent in the UK but they are now becoming a common sight, particularly in London where 600,000m² of green roofs are planned for installation by 2017. There are three main reasons why green roofing is becoming more popular including a growth in sustainable technology, the fact that they aid planning consent, and the huge benefits for the environment.
A green roof is the term applied when vegetation such as sedum, plants and trees, are installed on a building. There are three types of green roofs; Extensive Green Roofs, Biodiverse Roofs (Extensive Brown Roofs), and Intensive Green Roofs. At Liquid Plastics we have a range of options to suit all green roofing requirements.
There are many economic and ecological advantages of having green roofing including reducing the carbon footprint of the building, improving air quality, reducing the Urban Heat Island Effect, and increasing the thermal performance of a building.
Traditional waterproofing membranes such as bituminous, asphalt, single ply, and hot melt can all be used in Green Roof Systems however liquid applied membranes, like our Decothane material, offer many advantages both during installation and once in situ.
Primarily Decothane is completely cold applied, thus removing the need for any heat or naked flame on the roof. It can be easily applied around detail areas and is also proven to resist penetration by even the most aggressive roots. Our Green Roofing Systems are unique because they were the first on the market to include a seamless membrane that is certified by the BBA, and they also come with a 25 year guarantee.
