The establishment of perfect rule system of exterior wall thermal insulation

It is urgent to establish a perfect rule system for building external wall insulation

At present, the relevant departments have just put in place the standard of 30% energy saving. There are no national laws and regulations on wall insulation, no unified implementation and acceptance standards. Each place has its own way and the key additive HPMC, which affects the performance of external wall insulation materials, has no formal addition standard. And the production of external wall insulation materials manufacturers are mostly small workshops, is a mixture of good and bad. As soon as the market began to develop, the price war began. HPMC, a high price additive, made it impossible for regular large enterprises to produce. What small enterprises left behind was hidden dangers of construction and environmental damage. For example, in order to achieve good decoration and insulation effect, the cost per square meter of the integrated molding and installation system of insulation board and decoration should be about 300 yuan, but in the same project bidding, some enterprises offer a price of 150 yuan. To catch up with the price of upstream HPMC, the price gap can reach four or five thousand yuan from high to low. It is difficult for the manufacturer to choose, and the owner has no choice.

Building exterior wall insulation industry has broad prospects. As a new sunrise industry, the industry has rapid development, high profits, large market demand and broad prospects. At the same time, there are many problems, such as low entry threshold, a large number of gaps in the market, lack of well-known brand benchmarking, so it is urgent to establish a perfect building rules system for it.
