In southern China, in order to standardize the development of building energy conservation engineering, the new Chinese standards, industry standards and local standards and policies are strictly.
Compared to before the promotion of polystyrene particle thin plaster external insulation system, followed by inorganic light aggregate eps thermal insulation mortar exterior wall thermal insulation system, plaster external insulation system, extruded polystyrene board thin plastering exterior insulation system, pu heat preservation exterior wall thermal insulation system, rock wool board heat preservation decoration decoration integration of exterior wall thermal insulation system, etc.
Compared with many of exterior wall thermal insulation system, using insulation putty reflection heat insulation coating of exterior wall thermal insulation system has many advantages, such as: stable performance, waterproof, fireproof, etc.
With the passage of time, after the test of time and attempt to building energy efficiency, promotion of exterior wall thermal insulation system adopts the reflecting heat insulation coating of heat insulation putty has great advantages and characteristic.
For example;
Organic plate heat preservation material not flame retardant, easy to burn, heat-resistant, there is a big hidden trouble.
Should not promote integrating thermal insulation, decoration of exterior insulation system.
Jiang Yi academicians think that, in the south, shading of the building, cooling, ventilation is more important than the heat preservation, the south should be given priority to with thermal insulation. Heat preservation and heat insulation of exterior wall thermal insulation building energy conservation is southern China. Insulation energy-saving, because have a temperature difference. 'The farther south, on either side of the building wall temperature difference is smaller. Temperature difference is smaller, the less the insulation of the need, even need insulation. Proper exterior wall thermal insulation, energy-saving effect is better. External wall thermal insulation to reduce indoor and outdoor heat conduction, have obvious effect to reduce the energy consumption of air conditioning. May have a negative impact. As to the south, the temperature difference between indoor and outdoor building wall temperature difference on both sides will be more and more small, the smaller the difference in temperature, the less they need to heat preservation, the less they even need to heat preservation. For example,
if the temperature of northeast China - in winter 48 28, 20 in the home, temperature difference, the Shanghai nanjing is less than 15, south China. The temperature difference is big, thermal insulation can save a lot of energy consumption; But the southern temperature difference is small, to our strengths, to save energy. Need dominated by heat insulation, such as reflection heat insulation coating.
the south is suitable for heat insulation, ventilation and shading. Because the south temperature difference is small, insulation board didn't need so thick. Choose coefficient of thermal conductivity larger thermal insulation putty or insulation gypsum is more ideal. Reflective insulation coating used in most of southern China. For building energy conservation the north-south differences, to adjust measures to local conditions, the choice to adapt to the local climate environment, combined with insulation wall thermal insulation system. Is the south and north and south of energy-saving building in the transition area selection. Current implementation of the standard continuously perfect, the south has both construction energy conservation transformation has generally start. External wall insulation putty and reflective insulation coating as a kind of energy-saving retrofit scheme, is a very effective and reasonable choice. Exterior wall thermal insulation system in different weather conditions, not only can improve the comfort of indoor environment, and has very obvious energy saving effect.
