Q:Sound insulation and polystyrene insulation board which sound insulation better?

But its assembly is more complex and is not conducive to high-level construction, safety performance Dingzao cut to cut the salt tax is also poor, if the assembly is very easy to accident, and susceptible to natural factors and reduce its safety, As more and more emphasis on the protection of green today, it is bound to be replaced by steel scaffolding fastener type steel scaffolding with easy processing, easy handling, versatility and other advantages, is currently the largest use of China, the most common use of a scaffolding, but this scaffolding security is equally poor, the construction efficiency Low, scaffolding maximum erection height of 33 meters, can not meet the development needs of high-rise building construction bowl button assembly disassembly is relatively simple, the assembly performance is also good, more in the United States, China seems to use is not very wide But personally think that the future bowl button scaffolding will certainly be popular, there are prospects aluminum scaffolding is mainly lightweight, corrosion-resistant But not a high degree of construction, can not be high-level construction the disc does not seem to use the fastener with the bowl button type, universal joint do not understand So, personally think that in China fastening scaffolding or the mainstream, bowl button-style prospects are good
