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 thermal conductivity, thermal insulation board manufacturers, the thermal insulation of fine materials; ③, anti-corrosion aging: Long-term exposure to sunlight, Tangshan insulation board manufacturers, no aging, because resistant aging. 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. China is a big country useful energy consumption, since the late 1980s, the gradual implementation of energy-saving 30%, 50% and 65% of the three-step energy conservation, and the city began to expand in the conditional higher the level of implementation of energy-saving targets Try, for the fourth step is to prepare conditions for the establishment of energy-saving targets. Currently, I am abroad wall insulation technology has entered a stage of development by leaps and bounds, the country's external wall insulation has strict legislation, including the enactment of the Minister to make energy saving, energy law requires mandatory energy efficiency in buildings, facades specification mandatory standard insulation systems, as well as for the system and other standards-related component materials, insulation board factory in Tianjin, the technology and products have sufficient space to play. Regrettably, however, the study of the exterior insulation has been in a state of not deep enough, and even repeated the baseless assertion, in the understanding there has been a big misunderstanding. Moreover, Laizhou insulation board manufacturers, misunderstanding and even some understanding written textbooks and lectures across the country, to manufacture a variety of exterior insulation fog, but also to its development marked a mystery, non-normalization The imprint. As a staff member for many years engaged in exterior insulation study, I talk about these basic errors in understanding the practical point of view from the project, we hope to be able to cause some thinking people.
