Envirodek is a PIR insulated roof deck that has been specifically designed to support extensive and intensive green roof systems. Envirodek gives you the ability to transform urban spaces into greener environments, helping to reduce dust, smog levels, and retain rainwater thereby aiding flood management. Sedum mats and plug planting green roof solutions are currently proving to be really popular, with an increasing interest in semi intensive construction to encourage biodiversity. Envirodek is being specified on projects such as schools, healthcare and city centre buildings for visual appeal or to create a useable space. Envirodek should be installed with a suitable waterproofing membrane, prior to a green roof solution being installed.
