Green roofs, which offer protection of waterproofing, thermal insulation, improvement of the climatic environment as well as providing habitat for flora and fauna, have been incorporated into KRJDA's designs decades prior to their recent popularity. Our clients have benefited from their low maintenance, and in urban settings they are increasingly in demand as they help mitigate heat island effect.
