Second, the use of renewable building materials. Most of the buildings in Germany are treated using local native wood as the main building material. Such materials consumed in the growth process with minimal energy and produce the least carbon dioxide, both at the house after the demolition and reuse can be degraded. Third, focus on energy-saving renovation of existing buildings. On the one hand the development of relevant rules and regulations, to guide the insulation board manufacturer from the policy level to encourage businesses and individuals to modernize the energy-saving technological transformation of the old building, and the compulsory retirement measure; on the other hand the introduction of the energy-funded projects to promote the implementation of regulations and universal. Fourth, using a variety of eco-energy saving technologies. Germany developed and used a variety of eco-energy saving technologies Qingdao insulation board manufacturers, including rainwater recycling, sewage waste recycling, building insulation process, biodegradable technologies. ①, excellent fire performance: cement foam insulation board fire does not burn, fire performance to the A1 level. Maximum temperature of 400 ° or more. ②, excellent insulation properties: low coefficient of thermal insulation board factory in Shanxi for thermal insulation of fine materials; ③, anti-corrosion aging: Long-term exposure to sunlight Laizhou insulation board manufacturers, no aging, because it has anti-aging sex. ④, density, light weight: cement foam insulation board density about 180kg / m3. Reduce the weight of the building. ⑤, environmental protection: the environment and the human body without harm.
