Exterior insulation system is the 1970s global oil crisis period, the European countries to ease the energy issues and expand a range of policy-related work. Exterior wall thermal insulation and energy saving in only ten years of history, prior to this, since the related departments not positive, real estate developers on building energy conservation consciousness desalination, the market has no temperature do not fire, truly engaged in the external wall insulation energy conservation enterprise. And now, with the support of national policy, the needs of the market, encourage more enterprises and investors began to focus on building external wall insulation industry.
With the external wall insulation market development, insulation industries will slowly move towards standardization, technologies, products, brands, channels, competition, environment will be improved. With the countries on the importance of building energy-saving, energy-saving wall insulation industry is becoming more and more attention. China building energy efficiency standards by previous 30% to 50%, Beijing, Shanghai and other parts of the level of energy-saving standards require the city to reach 65%. Since this standard promulgated by the State Department attaches great importance to the world in the real estate, construction industry has focused on deployment, introduced a number of related policies, even for non-compliance of the building will not be approved. This gives the entire exterior insulation industry brings unprecedented opportunities.
Exterior insulation is nearly two years one of the first universal, except in the industry and municipal, provincial capitals and other economically developed cities, countries started to mandatory requirements for residential and public buildings must be energy-saving insulation, most of the country-level and in the following cities have not explicitly requested. In capital cities and other places, many places are just beginning to respond to national policies to promote energy-saving insulation, the country is also most of the gaps in the market. Even in Beijing, Tianjin has universal building thermal insulation of the city, the market competition has just started, still in an early stage of the competition is not too intense.
Exterior wall thermal insulation industry possess the distinguishing characteristics of Chaoyang industry: industries, industry development is faster, more profitable, market demand, the development prospects.
Building exterior facing material coatings are preferred
Exterior insulation not only solve the thermal insulation, thinning on mechanical requirements too rich wall thickness that can reduce the construction cost. Exterior insulation is the realization of building energy-saving mode of the most effective, as its exterior finish materials, building insulation coatings are preferred.
In our country, is more mature and are recommended for exterior insulation system are: thin polystyrene Board plastering exterior insulation system, adhesive polystyrene thermal insulation mortar external wall insulation system, no pouring concrete composite polyphenyl Board exterior insulation system, in-situ concrete composite polystyrene EPS Board exterior insulation system, mechanical fixation polystyrene EPS Board exterior insulation system. In addition, rock wool, polyurethane, extruded polystyrene plates, exterior insulation system are developed and applied. Western Europe and America building energy efficiency, is currently widely used exterior insulation system mainly bonded insulation board plastering, there are two insulation: flame retardant for expanded polystyrene Board and noncombustible-rock wool, paints for exterior layer. Exterior insulation system in Europe, was originally intended to cover the wall cracks.
Exterior wall thermal insulation coating of low thermal conductivity, ease of construction, oil, acid, alkali resistant, low contamination factor is the external wall insulation industry and the ideal insulation material. Exterior wall thermal insulation coating in variety, with ceramic insulation coatings, hydrophobic silica insulation coatings, rubber powder polystyrene particles external wall insulation coatings, etc. Ceramic insulation coating for water-based liquid coatings, from ultra fine hollow ceramic beads after pretreatment and provision of high quality emulsion, has the extremely high heat reflectivity and emissivity, can effectively reduce buildings summer cooling and winter heating energy consumption. Hydrophobic silica insulation coating is made from high quality aluminum silicate sepiolite cashmere, fiber, perlite, silicone and other high-quality insulation materials and polymer composite, excellent insulation properties are widely used in wall, tanks, heat insulation of cold storage, pipes etc. The rubber powder polystyrene particles external wall insulation coatings is a new type of insulation, the rubber powder and polystyrene granules of composed of two main components.
At present relatively good insulation coatings with good weather resistant properties, thermal conductivity, low thermal insulation performance stability, high softening, freeze-thaw resistance coefficient, anti-aging; grassroots deformation adaptability, effectively preventing cracks in walls; system without cavities, resist negative air pressure ability, suitable for multi-tiered and high-rise buildings; permeability, respiratory functions, both have good water resistance, but also can untangle the insulating layer of moisture; construction of convenience and speed, can more multidimensional construction; fire resistance rating up to B1 level and above, and many other comprehensive advantages.
Exterior wall thermal insulation coating development space great
External wall insulation with large market prospects, while many paint companies seize the opportunities that the external wall insulation industry successfully entered, but the development of the external wall insulation for ten years, the entire building insulation industry has been in the Bush leagues of the State, enterprises, little fragmented technology market communication. So far, the industry is not a well-known national and professional external wall insulation coatings brands.
The relevant provisions of the countries formally before the external wall insulation coatings has not received the attention, even today, in some cities still uses relatively backward in the external wall insulation materials and technology, it is understood that the internal market, some large cities, especially level city exterior insulation work done relatively well, such as Beijing and Shanghai and other major cities, basic restrictions relatively backward in material and workmanship and the use of listing; but many secondary cities or other small cities building insulation market order is chaos, the use of materials and construction technology is rather backward. However, the external wall insulation materials market needs still great, with economic development and national external wall insulation industry related policy of further improvement of the external wall insulation materials market will further expand and norms, as the ideal material, external wall insulation coating of broader market space.
