Everyone is very afraid to choose the top floor when buying a house, the top floor is not only very hot in summer, but also very cold in winter, so now many people like to use thermal insulation materials on the top floor, the most popular roof insulation materials are polyurethane rigid foam, polystyrene board thermal insulation layer, FS cement fly ash thermal insulation roof, FB new composite roofing panel, etc., so what are the types of thermal insulation materials? 1. Polyurethane rigid foam Polyurethane rigid foam is a low-density microcellular foam material with closed-cell structure, which has small thermal conductivity, good thermal insulation performance, low water absorption and convenient construction and operation. 2. Polystyrene board insulation layer Polystyrene board is a roof panel made of cement and crushed polystyrene foam.
The polystyrene board is located between the surface layer of fine stone concrete and the waterproof layer, in addition to the effect of heat insulation, it also has the role of an isolation layer to prevent the surface layer of fine stone concrete from cracking the waterproof layer when it expands and contracts. At present, the commonly used overhead prefabricated reinforced concrete slab has only a gap of 250mm between it and the parapet, which cannot prevent the heat from being transmitted to the room, and the dark waterproof layer under the gap will also absorb heat, resulting in the local temperature rise of the room. 3. FS cement fly ash insulation roof FS type insulation material is made of fly ash, sulfoaluminate cement, foaming agent and foaming agent and other materials at room temperature and pressure.
Its environmental protection and comprehensive utilization are good. The density of FS type insulation material is small, so the thermal conductivity is very low, so the insulation performance is good. Fourth, FB new composite roof panel FB new composite roof panel set lightweight, heat preservation, heat insulation and waterproof and other functions in one.
Its overall dimensions are 1200mm 700mm 100mm, the roof panel will be the roof insulation, waterproofing, leveling on-site wet operation process changed to factory production, improve efficiency, roofing engineering construction speed can be increased by 2 3 times, the weight of the traditional roof is reduced by about 230kg The new composite roofing panel adopts three layers of thermal insulation layer of lightweight structural board, thermal insulation board and air layer, and the thermal insulation effect is significantly better than the traditional roofing method. The above 4 kinds of thermal insulation materials recommended to you are very good, here is a reminder: the choice of thermal insulation materials is to choose the form, physical characteristics, chemical characteristics, thermal insulation performance in line with the use of the environment, environmental protection level to meet the design needs of thermal insulation materials, after accounting costs, the final determination of the thermal insulation materials to be used.

Many people feel that living on the top floor is very good, and they can make good use of the area on the roof and use more space. However, if the top floor is not well insulated, it will be very hot in the summer and very cold in the winter. It can be seen that it is very necessary to make a thermal insulation layer on the top floor, so what are the thermal insulation materials?
Next, let's find out together!
There is polyurethane rigid foam, which is a new type of microcellular foam material with closed-cell structure and low density, its thermal insulation performance is very good, the thermal conductivity is very small, and the water absorption rate is also very low, and the construction operation is also convenient. There is also a polystyrene board thermal insulation layer, which is between the waterproof layer and the fine stone concrete surface layer, which not only has the effect of thermal insulation, but also can be used as a thermal insulation layer.
Commonly used insulation for roofs.
1. Polystyrene board, polystyrene board is divided into expanded polystyrene board and extruded polystyrene board. Expanded polystyrene board, also known as EPS board, has a very good thermal insulation effect, and it is not expensive, but the strength is not very good. Extruded polystyrene board, also known as XPS board, will be more expensive than expanded polystyrene board, but it not only has good thermal insulation effect, but also has a good moisture resistance and high-strength effect.
2. Rock wool board, the thermal insulation effect of this material is not very good, but it has waterproof and flame retardant properties.
3. Rubber powder polystyrene particle insulation slurry, the thermal insulation effect of this material is not very good, and it also has high requirements for construction technology. However, the flame retardant performance is good, and it can also be used as a waste product**.
4. Polyurethane foam material, this material not only has a good thermal insulation effect, but also has good waterproof performance, and is most suitable for roof waterproof and thermal insulation, but it will be slightly more expensive.
Conclusion: What are the above contents about thermal insulation materials? I hope it can help you. I believe that after the introduction of the content, what will you know about the insulation materials commonly used in roofs? If you have more understanding, if you have a need in the future, you can refer to it.

Thermal insulation materials include aluminum silicate insulation materials, phenolic foam materials, rock wool boards, thermal insulation color steel sandwich panels, porous thermal insulation panels, extruded plastic panels, expanded vitrified microbeads, rubber and plastic insulation materials, etc. Among them, aluminum silicate insulation material, also known as aluminum silicate composite insulation coating, is a new type of environmentally friendly wall insulation material, with natural brazing as the main raw material, adding a certain amount of inorganic auxiliary materials through composite processing to make a new type of green inorganic one-component packaging dry powder insulation coating.
Phenolic foam material is a polymer organic hard aluminum foil foam product, which is foamed by thermosetting phenolic resin, which has the characteristics of lightweight, fireproof, non-combustion, smoke-free, non-toxic, non-dripping, wide range of temperature, no shrinkage and non-embrittlement in low temperature environment, and is an ideal thermal insulation material for HVAC engineering.
As one of the most widely used thermal insulation materials, rock wool board has good fire performance and moisture absorption performance, and is very popular in the south. However, the thermal insulation performance is relatively poor, and it is not suitable for northern residents.
Extruded plastic board: XPS polystyrene extruded plastic board is used as the external wall insulation material of the building, and when the masonry project of the main body of the building and the external wall is completed, the special interface agent for XPS is applied to the bottom mortar. The thermal conductivity of industrial thermal insulation materials is often lower, and the specific index requirements are closely related to the industry field and specific application.
Porous materials. It uses the pores contained in the material itself to insulate heat, because the thermal conductivity of air or inert gases in the voids is very low, such as foam materials, fiber materials, etc.; Heat-reflective materials have a high reflectivity and can reflect heat, such as gold, silver, nickel, aluminum foil or metallized polyester, polyester film, etc. Thermal insulation materials are mainly divided into three categories: porous materials, heat-reflective materials and vacuum materials.
