Extensive Green Roof Systems:
Sempergreen is a leading European green roof company, with branch locations in USA and China. Sempergreen develop and produce green and sustainable building products such as green roofs, blossoming roundabouts, erosion-resistant embankments and green-covered sound barrier walls. For 14 years, Sempergreen has been successfully laying its lightweight sedum mats all over the world – in China, Holland, France, Germany, Spain, Italy and the USA.
Sempergreen China produces specially-developed lightweight sedum mats for extensive green roof gardens. GreenRoof Asia represents Semprergeen in Hong Kong and has been working closely with Govert Verdoorn, director and general manager of Sempergreen China, to better adapt the Sempergreen sedum mats to the local southern China environment.
Profeco is a Hong Kong-based sustainable engineering company that carries out energy conservation and carbon reduction audits and consultancies. They also devise, manufacture and install green technology using their highly qualified team of Carbon Auditors, Mechanical Engineers and Authorized Person (AP) / Registered Structural Engineers (RSE).
Green-Works Asia Ltd is a Hong Kong based environmentally conscious consultancy and contracting organisation that offers specifications and installations of advanced, high performance waterproofing systems for roof decks, particularly where green roofs are being installed.
Depending on the particular requirement, the company offers either cold applied liquid membrane systems manufactured by Sika in Europe – including the former Liquid Plastics range – through to complex crystalline technologies from Xypex in Canada for applications to concrete. Being innovative with its approach to problem solving – either for a refurbishment or newbuild project – it would not be unusual to see both technologies being applied on the same roof, to give genuine long term waterproofing protection to the structure.
In addition to waterproofing, green-works also offers energy saving equipment for reducing air conditioning costs, plus a predictive device that measure solar and wind gain for use in determining the viability of investing in panels or turbines.
