Characteristics of PUB·F type polyurethane rigid foam waterproof and thermal insulation integrated board

The characteristics of PUB·F type polyurethane rigid foam waterproof and thermal insulation integrated board are as follows:

Integrated waterproofing and thermal insulation: effectively solves the leakage risk of roof waterproofing and thermal insulation projects, ensures thermal insulation effect and waterproof performance, and overcomes the limitations of traditional materials that are waterproof but not thermally insulating, and thermal insulation is not waterproof.

Simplified structure and high efficiency: The system structure is simplified, construction efficiency is greatly improved, and the construction period can be greatly shortened. For example, in roofing projects, more than ten processes can be reduced to three processes, namely the structural layer, the rigid polyurethane foam waterproof insulation layer, and the protective layer.

Reduced roof load-bearing: The application of this integrated panel reduces the load-bearing of the roof system (50~160㎏/㎡), reducing the burden on the building structure.

Reasonable overall cost: Although the unit price of polyurethane rigid foam materials may be higher than traditional thermal insulation materials, because it has multiple functions of thermal insulation, waterproofing, and air isolation, it saves the cost of waterproof layer, air barrier layer, insulation layer and leveling layer, which reduces the cost of the entire roof.

Excellent material properties:

The core layer is made of polyurethane rigid foam: thermal conductivity ≤0.024 W/(m·K), compressive strength ≥0.20 MPa, tensile strength ≥0.20 MPa, heat resistance ≤120°C, closed cell rate exceeding 90%, and excellent thermal insulation and waterproof properties.

Use special supporting materials for construction: good quality and reliability, which can ensure construction quality and long-term stable operation of the system.

Adaptable:

Wide temperature adaptation range: It can maintain stable performance in the temperature range of -50℃ to +150℃, and can be used in all areas including severe cold and high temperature areas.

Strong adaptability to the base layer: It can be firmly bonded with various materials such as wood, metal, masonry, and concrete to form a seamless continuous shell to adapt to the construction requirements of different base layers.

Long service life: The polyurethane material has a stable porosity structure and is basically a closed-cell structure. It not only has excellent thermal insulation performance, but also has good freeze-thaw resistance and sound absorption. Under normal use and maintenance conditions, the service life can reach more than 30 years, and maintenance is simple and convenient.

Remarkable energy-saving effect: low thermal conductivity and excellent thermal insulation performance. It is one of the thermal insulation materials with the lowest thermal conductivity and the highest thermal resistance among all domestic building materials. For example, a 20 mm thick PUB·F board can meet the national energy saving standards, and a 40 mm thick PUB·F board can meet the energy saving requirements of 65%. It can also compensate for deformation caused by thermal expansion and contraction, bringing long-term energy saving benefits to the owners.

Convenient and fast construction: On-site spraying or prefabricated plate installation can be used for construction. The degree of mechanized operation is high, the construction speed is fast and the efficiency is high. A set of imported equipment can complete 800-1,000 square meters of construction every day under good conditions, saving 80% of the construction time compared with conventional waterproof and thermal insulation materials, reducing labor intensity, improving the working environment, and reducing environmental pollution.
