Maybe you do not know, in order to be able to block the summer heat and winter cold, the provisions of the state in the construction of buildings must be insulation for building a "coat", in order to reduce indoor air conditioning in summer and winter indoor heating outflow. Building energy efficiency has become the current all the most direct and effective way of energy saving in energy conservation and emissions reduction measures.
For years, however, several fire made the controversial "coat". Shouted as he shouted as energy saving, fire prevention, and the government worry, cry foul. People wondered, what's the matter with building external wall thermal insulation? This "coat" exactly is what material made of?
Yi insulation fire are hard "issue"
The actual situation is what kind of? The prevalence of "playing tricks" exposed the "hidden rules" of the industry.
Production suppliers, said: "prices for orders not to give the real thing, flame retardant cost is too high, must be at a loss, so he never produce qualified products."
Contractor, said: "add do not add flame retardant from appearance to look not to come out at all. The customary to inspection agencies inspection is flame retardant products, and to reduce the cost, construction use need not add."
Engineering supervision party, said: "authoritative testing institution to the certificate of approval, supervision and what is true? Later also want to acting."
Finally to fire acceptance, flammable materials have bag inside the wall, when acceptance of property developers and to try their best to block the metope of its a mess.
In this way, "playing tricks" is popular, hall became the "hidden rules" of the industry. The ecosystem of the interests of all parties to form at the same time, but for future buried under the endless fire hidden trouble.
China's building energy-saving materials association statistics show that in the current domestic building energy efficiency, more than 80% of exterior wall thermal insulation material of polyurethane, extruded plate and insulation of polystyrene and other organic materials. This, however, how many of them are with flame retardant, no department to be told. There was a fire accident in, only to "clear".
From Beijing to Shanghai and shenyang, three fires three years, during which a small fire, the alarm strikes. Reasons, according to official information released by the fire were from building exterior wall thermal insulation materials ignited by a spark. People can not help but think, this "coat" fire over how to meet? Start building energy saving, more than 20 years, why can't the original "energy-saving pioneer" to the "culprit"?
In more than 20 years, organic combustible material is popular, "is there no alternative technologies and alternative materials, and new regulations will fundamentally put an end to it happen?
In fact, the country in 1995 and 1995, has A different codes and standards, building exterior wall thermal insulation materials can be divided into non-combustible material (grade A), (B) flame retardant materials and flammable materials (grade C) and so on different levels.
On March 5, 2011, the ministry of public security has issued the "65", defined the building insulation materials must be used a-class non-combustible material.
However, is that these can be fundamentally put an end to the provisions of the fire hazard, but rejected by some provinces and cities to varying degrees.
Support innovation or protection behind when put on building trust "coat"?
The ministry statistics show that, our country has both 40 billion - 40 billion square meters. Among them, according to the plan each year to 400 million square meters of building energy-saving renovation. At the same time, every year new start construction area is growing at a speed of 1.7 billion - 2 billion square meters, and is more tall buildings.
For such A big market demand, combined with the regulation of "65", A grade material can satisfy the supply? For class B and class C material, after more than 20 years of industry development, the enterprise has formed its own profit ecosystem, to no one willing to turn around. Market in A variety of "struggle" generated in the brief throes, "grade A material capacity theory" grew louder.
A grade material really insufficient capacity? Figures show that only with vacuum insulation board and foamed cement, for example, wuhu grade A material base established in January 2011 to June 18, half an year to achieve the annual production capacity of 100 million square meters. Has also started in Beijing and xinjiang construction during two annual output of hundreds of millions of square meters of vacuum insulation board factory. Wu Handa rights as in central China's largest collection of new light weight energy saving wall materials and mechanical equipment research and development, production, sales in A body specialized production enterprise, also increased the class A building board, fireproof composite sandwich panels, fire solid board, fireproof hollow board, fireproof protein foam board and other building fire prevention board production and research and development.
These data show that the market has strong self adjustment ability, "insufficient capacity theory" itself is a false dichotomy.
