Second, the best choice for exterior insulation system configurations: no cavity? EIFS preference should be given no cavity system that no cavity system compared to the system in terms of a cavity, in particular, its wind pressure and strong anti-negative pressure capability, Beijing insulation board manufacturers, safety and reliability higher It seems to have reached a consensus, Tangshan insulation board manufacturer, in fact, not at all. It has applied for 26 patents, insulation board manufacturers, 13 of which are invention patents, 13 utility model patents. The patents in the production of carbon dioxide foam technology energy-saving insulation materials, insulation board factory in Shanxi Province, has recycled polystyrene insulation materials production of energy and environmental protection. Carbon dioxide foam technology can reduce carbon dioxide in the air, slowing the Earth's greenhouse effect, the full realization of the comprehensive utilization of resources and protection of the global environment. Now, there are four patents pending, the state high-tech companies are also application process.
