Do you know why the building we live in is warmer than the original square house? The main reason is not the change of heating method, nor the cause of global warming, but because the building was designed with wall insulation during the construction. The general bungalow building does not have these, then what is the wall? What about the insulation layer ? The following small series will take you to a specific understanding. First, what are the wall insulation materials? 1, polystyrene foam board a. Polystyrene foam board is one of the three common interior wall insulation materials. Also known as a foam board or an EPS board, it is a white object which is formed by heating a pre-formed expandable polystyrene bead containing a volatile liquid foaming agent and heating it in a mold. b. Its advantages are small density coefficient, good impact resistance, sufficient capacity to buffer external impact force by changing and returning shape; independent bubble structure, small area damage will not affect the entire wall; The surface has low water absorption rate and good anti-penetration performance, and can effectively avoid wall problems such as mold and falling off after the wall is wet. 2, polyurethane foam a. It is a special polyurethane product in which a polyurethane prepolymer, a foaming agent, a catalyst and the like are filled in a pressure resistant aerosol can. When the material is ejected from the aerosol can, the foamed polyurethane material rapidly expands and solidifies to react with the air or the moisture in the contacted matrix to form a foam. b. Its advantage is that the insulation performance is good. The thermal conductivity is about 0.025, which is a good material for building insulation; it has good waterproof performance. The foam pores are closed, the sealing rate is 95%, and the rainwater does not seep through the pores; the bonding performance is good. It can be bonded to wood, metal, masonry, glass and other materials very firmly, not afraid of high winds. Second, what role does the wall insulation layer have? 1. Some people do not understand the role of external wall insulation, and it does not matter whether they do or not. This is a big misunderstanding. The external wall insulation has a great effect. One of the important manifestations is the protection of the main structure, because the insulation layer is placed outside the building envelope. 2. The outdoor climatic conditions cause large temperature changes inside the wall, which occur in the outer thermal insulation layer, buffer the stress caused by structural deformation due to temperature changes, prevent large temperature changes in the internal main structure, and effectively improve the main structure. Durability, building life extension. 3, the summer temperature is too high, and the winter is too cold, people are very uncomfortable, so many owners will insulate the external wall. Through the external wall insulation material can not only improve the indoor environment, but also have the effect of thermal insulation. This not only greatly reduces the wind and moisture damage, but also increases the indoor dryness, avoiding indoor mildew spots, and so on. Third, the wall insulation layer construction process 1. Scope of application of this regulation: Polystyrene board as insulation material, polymer bonding mortar as bonding material, polymer plastering mortar as surface layer, alkali-resistant glass fiber coated mesh cloth as reinforcing material and supplemented by card Construction and acceptance of external thermal insulation systems for industrial and civil buildings with anchoring. 2. Product material requirements: The technical performance of all materials used in exterior wall insulation construction shall meet the relevant national standards. 3. Construction personnel requirements: According to the project size and schedule requirements, organize the construction team. Before starting work, the construction personnel will be educated in various aspects such as thinking, craftsmanship, quality and safety to ensure the quality of the construction project and the progress of the project. 4, the requirements of the construction environment: the normal construction operating environment temperature of the external wall insulation construction is 5 ° C ~ 35 ° C. External wall insulation is generally completed at the time of construction. As consumers want to check the insulation layer, they should say hello to the relevant personnel at the time of acceptance. We will also communicate with the quality problems at the time. The insulation layer is still very important. For more exciting home improvement information, please continue to pay attention to the decoration home network.
