Roof and basement roof greening increasingly by the design unit, the total package and the owners of the attention, and with the acceleration of urbanization process, a large number of urban space is occupied useful life for composite wood by the building, must be in a variety of ways to compensate for the loss of natural space, Roof greening is an ecological compensation means. According to statistics, the city roof occupies 15% to 30% of the total area of the city, the roof is an unused huge space resources, can be on the urban environment, especially on the urban heat island effect have a positive impact. The United Nations Environment Program (UNEP) shows that when a city’s total roof greening reaches 70% of urban buildings, the amount of carbon dioxide in the city will drop by 80% and summer outside wood stair railings temperatures will fall, and the urban heat island effect will be basically lifted. In short, the roof greening system for improving the ecological environment and landscape, improve the ambient air quality, reduce building energy consumption, reduce the urban heat island effect is of great significance. Normative enforcement. It is understood that many countries and regions in the roof greening carried out a number projets using wood and plastic of active exploration, developed the relevant policies and laws and regulations to promote the popularity of roof greening. The roof greening as the city’s infrastructure, the new building to set a minimum roof green area, the existing building, through direct financial subsidies to promote the roof green. At the same time, actively study the roof green sets of technology, product specifications, construction and supervision regulations, the introduction of roof greening implementation approach. At present, the planting roof system has been the consensus of all sectors of the community, will grasp the opportunity for market development, based on the existing materials on the basis of optimization and innovation of new resistant recycled plastic composite fence ireland
root puncture waterproof material.
