Anyone living on the top floor has a common annoyance: "It's cold in winter and hot in summer." Don't look at living on the top floor. There seems to be a big platform. There is more space for people to use. It looks like it looks good. Sun exposure, storms, and brunt. Is the roof of the households. Therefore, the insulation measures on the roof are also extremely concerned by the “top-level†people. Firstly, attention is paid to the thermal insulation materials , and secondly, how to use the space on the roof to achieve the thermal insulation effect. With respect to thermal insulation materials and thermal insulation methods, many people may not understand it too well or understand too much. Below, here are the new roof insulation materials and insulation methods Which are you? Thermal insulation material introduction Thermal insulation material, polyurethane rigid foam Polyurethane rigid foam is a kind of low density microporous foam material with closed-cell structure. It has low thermal conductivity, good heat insulation performance, low water absorption and convenient construction operation. China's use of polyurethane rigid foam on the roof is still in its infancy, mainly using direct spraying. It is usually spray-formed on site to work on any roof with a complex structure. Usually 4-6 people can spray more than 15m3 per day, according to the spray thickness of 30mm, the daily spraying area of ​​500m2, several times the traditional material. Thermal insulation material II. Polystyrene board insulation Polystyrene boards are roof panels made of cement and crushed polystyrene foam. The polystyrene board is located between the fine stone concrete surface layer and the waterproof layer. Besides the heat insulation effect, the polystyrene board also acts as a barrier layer to prevent the surface layer fine stone concrete from cracking and breaking the waterproof layer. However, the commonly used overhead prefabricated reinforced concrete slab and the parapet only have a gap of 250 mm, which cannot prevent the heat from being transmitted to the interior. The dark waterproof layer under the gap also absorbs heat, resulting in a rise in the local temperature. In addition, with the same heat insulation effect, the polystyrene board heat insulation layer can reduce the cost and save money. Compared with prefabricated reinforced concrete overhead insulation, the cost of polystyrene insulation is reduced by approximately 2.66 yuan/m2, and the cost of roof parapets is reduced by 0.45 yuan/m2 (1/2 brick) or 0.65 yuan/m2 (3 /4 Brick Wall). Compared with the foamed concrete heat insulation layer, the cost of the polystyrene board heat insulation layer can be reduced by 5.66 yuan/m2. However, the strength of the polystyrene board is low, the fireproof performance is not very good, and the construction performance is poor. Thermal insulation material III. FS cement fly ash insulation roof FS-type heat-insulating materials are made of fly ash, sulphoaluminate cement, foam stabilizing agent, and foaming agent, which are cast and foamed under normal temperature and pressure. Its environmental protection and comprehensive utilization are good. FS type thermal insulation material has a low density, so its thermal conductivity is very low, so its thermal insulation performance is good. More importantly, it has a uniform closed-cell structure, and its water absorption rate and natural moisture content are very low. It not only eliminates the need for water-spraying and wet-out steps during construction, but also prevents moisture from being absorbed by the heat-insulating layer after the cement mortar leveling layer is completed. The ills. In addition, since the FS insulation roof can reduce the thickness of the roof, the height of the parapet, the height of the roof pipe, and the height of the roof, the cost can be reduced and the roof load can be reduced. Convenient handling during construction can reduce labor intensity and improve efficiency. Thermal insulation material four, FB new composite roof panel FB's new composite roof panel combines lightweight, thermal insulation, thermal insulation, and waterproof functions. Its external dimensions are 1200mm*700mm*100mm. The roof panel will change the roof insulation, waterproof, and equal site wet work procedures to factory production to increase the efficiency. The roof engineering construction speed can be increased by 2-3 times, compared with the traditional roofing. The weight loss is about 230kg/m2. FB's new composite roof panel is made of three layers of lightweight structural panels, insulation panels, and air layers. The insulation and heat insulation effects are significantly better than traditional roofing methods. In addition, it adopts a composite waterproof system with rigid waterproofing of the structural panel itself and flexible waterproofing of the TS membrane. The joints at the seams of the panel are processed by two seams, which are a sealing material caulking, sealing, and a waterproof membrane, to achieve rigidity and flexibility. , double insurance waterproof effect. Thermal insulation method introduction In addition to the use of interior decoration materials for insulation on the roof, everyone can also make full use of the space on the roof and transform it to achieve thermal insulation. 1, air circulation insulation method: that is, in the roof cover about a 30cm hollow sandwich, the sun exposure, the roof below the flow of air, can effectively isolate the heat transfer; 2, water insulation method: This method is a lot of residents like to use the insulation method, the roof is usually shallow blisters, about 15cm depth, effective and reasonable to reduce the indoor temperature, relatively simple, but the higher the roof quality requirements; 3, white paper reflective method: that is, laying a smooth surface on the roof of white paper (tin foil), not easy to oil, while strong reflective insulation; 4, can be laid in the roof of 10 cm thick pearl sand insulation layer, add a layer of cement prefabricated insulation board; if the reinforced concrete cast-in-place roof, can be stored on the top 20 cm thick layer of flowers and plants, both landscaping, There is thermal insulation. The above is a brief introduction to the new roof insulation material. Here we can refer to it when choosing the roof insulation material . I hope to help everyone.
