What is the energy-saving effect of polyurethane hard bubble insulation decorative integrated board

The polyurethane hard bubble insulation decorative integrated board has excellent performance in energy saving effect. Its core advantages are reflected in its extremely low thermal conductivity, waterproof and moisture-proof performance brought by high closed porosity, durability improved by the characteristics of thermosetting materials, and quality stability guaranteed by factory prefabricated processes. The specifics are as follows:

1. Low thermal conductivity and excellent thermal insulation performance

The thermal conductivity of polyurethane hard bubbles is 0.018-0.024W/(m·K), which is only 1/3 of that of traditional insulation materials (such as rock wool, EPS). This means that at the same thickness, its insulation effect is significantly better than other materials. For example, the construction thickness only needs 40mm to meet the national energy-saving requirement of 65%, while traditional materials may need to be thicker to achieve the same effect. This characteristic allows the thickness of the building exterior walls to be greatly reduced, indirectly increasing the indoor use area.

2. High closed porosity, outstanding waterproof and moisture-proof performance

The closed cell rate of polyurethane hard bubbles exceeds 90%, and some products even reach more than 95%. They are highly hydrophobic and do not absorb moisture or seep water. In humid environments, its thermal insulation performance is still stable and will not increase the thermal conductivity due to water absorption. This feature is especially suitable for scenes such as cold storage and refrigerators that require high humidity, as well as building exterior walls in rainy areas.

3. Thermoset material with excellent durability

Polyurethane is a thermosetting material. It will not soften and drip at high temperatures, but will form a coke layer to protect the inner layer, effectively preventing the flame from spreading. Its softening temperature can reach 120℃, which is much higher than EPS (about 70℃) and XPS, and its heat resistance and flame retardant performance are better. In addition, polyurethane is difficult to degrade under natural conditions and has a service life of more than 30 years, which is the same as the building, reducing the cost of later maintenance.

4. Factory prefabricated process, high quality controllability

The polyurethane hard bubble insulation decorative integrated board adopts factory prefabricated process, and integrates laminates, plate split robots and other equipment through automated production lines to achieve efficient composite of core materials and decorative surface layers. This process avoids quality fluctuations caused by on-site wet operations and ensures consistency of the thermal insulation performance, fire resistance level and decorative effect of the board. At the same time, factory production improves construction efficiency and shortens construction period.

5. Comprehensive energy saving and significant benefits

Reduce energy consumption: Buildings using polyurethane hard bubbles can save 20-30 kWh of electricity per square meter per year, and the cumulative power savings in 70 years reach 1400-2100 kWh/square meter, which is equivalent to reducing a large amount of coal consumption.

Improve living comfort: effectively adjust the indoor temperature, warm in winter and cool in summer, the temperature difference can reach 3-5℃, reducing the frequency of air conditioning and heating.

Comply with green building standards: Polyurethane hard foam is fluorine-free foam, and does not use harmful substances prohibited or restricted by the state. They are green and environmentally friendly and meet the requirements of energy conservation and emission reduction.
