The materials used in the thermal insulation layer should have the properties of thermal insulation, heat insulation, light weight, non-combustible, environmental protection, and durabilityTherefore, when choosing thermal insulation materials, it is necessary to consider comprehensively according to the specific situation and material characteristics. Here are some common insulation materials and their pros and cons:
1.Polystyrene foam board:It is a commonly used thermal insulation material, with excellent thermal insulation performance, light weight, non-combustible, environmental protection, but high water absorption, and it is easy to crack after long-term use.
2.Rock wool:It is also a commonly used thermal insulation material, which has a good thermal insulation effect and good fire performance, but has high water absorption and is easy to age after long-term use.
3.Fiberglass wool:It is often used for the thermal insulation of building exterior walls, with excellent thermal insulation effect, light weight and durability, but it is not suitable for use in high-temperature environments.
4.Polyurethane foam:The thermal insulation effect is good, the waterproof performance is good, the strength is high, and the service life is long, but the first is higher.
Taking into account some of the properties of the above materials, such as:Polystyrene foam board and polyurethane foamIt has excellent thermal insulation effect and is non-combustible and environmentally friendly, and has good thermal insulation performance and thermal insulation effect. However, it is also necessary to consider the specific situation when choosing, such as the construction environment, cost budget, environmental protection requirements and other factors. In addition, some new green materials such as foamed cement and calcium silicate board also have good thermal insulation performance and can also be used as candidate materials for thermal insulation.
In general, when choosing a thermal insulation material, factors such as thermal insulation performance, lightweight, non-flammability, environmental protection, durability and cost should be comprehensively considered. In the specific application, it is also necessary to select according to the actual situation and material properties.
