Tianjin Steel breathable waterproof membrane water vapor permeability long roll of film is laid outside the building insulation layer overlying layer of film, and water vapor permeability of membrane technology by strengthening the building is airtight, watertight to achieve energy savings protect the living environment, thereby enhancing the durability and comfort of the building, can more effectively ensure maintenance of the structure (walls and roof) of dried and play a significant effect. 1. Strengthen the building air tightness, water tightness Practice has proved that no matter what form the facade or roof laying form, they can not guarantee airtight building envelope. To the exterior wall, it's difficult to avoid cracking plaster, siding lap is difficult to close, and even more simple masonry block can not be "an unventilated wall." These problems in the construction of yin and yang angle lap around windows and doors is more significant. Through these non-closed pores, air and moisture to invade envelope, and thus the energy consumption of buildings, durability and comfort have a serious impact. Polyethylene waterproof breathable membrane, a composite of PP + PE + PP three together, is a new waterproof green building materials, widely used in the country, also exported to Europe, South America, Russia and other regions and countries, 0.3mm thickness , 0.49mm and 0.65mm, prices vary, the steel roof, train stations, high-speed rail, curtain wall, ah, have applications slope surface, the effect is certainly the majority of users. Factory direct supply, both to ensure quality assurance of the price, the package that you buy happy, at ease. Air will invade the formation of the internal structure of the building envelope convection cycle, will also reduce the effective thermal resistance of the insulation layer, resulting in more energy consumption. Similarly, the impact of different insulation materials flow is somewhat different. According to the method to determine the height of buildings to put the line, multi-storey buildings or high-rise building, you can fall from the top with a big line hanging vertically stretched wire to find the rules, can be based on the transverse horizontal floor elevation or construction ± 0.000 500mm line up for the horizontal reference line cross-loop control. According to tune vertical lines and insulation thickness, each step frame on both sides of the line of control on the horn playing, and then pull the horizontal lines do pass mark blocks.
