The full name of PU panel is polyurethane sandwich panel or polyurethane composite panel. It is a high-performance thermal insulation sandwich panel for construction. It is made of polyurethane hard foam as the insulation layer and combined with bimetallic surfaces, single metal surfaces or non-metallic surfaces. It complies with the national standard GB/T 23932-2009 and is a new energy-saving plate that replaces the old standard JC/T868-2000. PU boards occupy an important position in the modern construction industry due to their excellent performance and wide range of applications.
Material properties of PU panel
PU boards have several significant advantages. First of all, its thermal conductivity is extremely low and its thermal insulation properties are excellent. It is one of the best insulation materials currently on the market. This characteristic makes PU panels particularly important in cold areas or buildings that require a high degree of thermal insulation. Secondly, PU boards not only have excellent thermal insulation performance, but also have good fire resistance. The combustion performance reaches B1 level, which can effectively prevent the spread of fire. In addition, PU boards also have the advantages of non-toxic and odorless, good waterproof performance, easy installation, and short construction period. These characteristics make PU panel the first choice for building envelope materials.
Application of PU boards in steel buildings
Due to its excellent performance and good economic benefits, PU boards are widely used in various types of steel buildings, including energy-saving industrial plants, logistics warehousing, integrated houses, civil buildings and residences, etc. In steel structure buildings, PU panels are used as enclosure materials for exterior walls and roofs. They can not only provide efficient thermal insulation effects, but also significantly improve the overall aesthetics and service life of the building.
Industrial plants and logistics warehousing: In the field of industrial plants and logistics warehousing, PU boards are popular because of their durability, thermal insulation, waterproof and fireproof properties. These buildings often have high requirements for insulation and fire resistance. PU panels can meet these needs while reducing energy consumption and improving building energy efficiency.
Integrated house: An integrated house is a quickly built temporary or permanent living space that has particularly strict requirements on materials. PU panels have become an ideal choice for integrated houses because of their light weight, high strength, easy installation, and superior thermal insulation performance. It can not only effectively improve living comfort, but also shorten the construction period and reduce construction costs.
Civil construction and residence: In the fields of civil construction and residence, PU boards also show their unique advantages. As people’s requirements for the living environment continue to increase, the environmental protection, energy saving and comfort of building materials have become important considerations. PU panel has become one of the preferred building envelope materials for modern residential buildings due to its non-toxic, odorless, thermal insulation, waterproof and fireproof properties. Summarize
As a high-performance thermal insulation sandwich panel for construction, PU panel has been widely used in the field of steel buildings due to its excellent thermal insulation performance, good fireproof and waterproof performance, convenient installation, and short construction period. Whether it is industrial plants, logistics warehousing, integrated houses or civil buildings and residences, PU panels provide efficient, energy-saving and comfortable building envelope solutions with their unique advantages. With the continuous advancement of technology and people’s increasing requirements for environmental protection and energy saving, the application prospects of PU boards in the construction industry will be broader.
