Product Details
The 75mm thick 4-rib PUF panel roof is composed of multiple layers of composite structures, mainly including:
- Surface material: generally, high-strength and corrosion-resistant materials, such as color steel plate, aluminum zinc plate, etc., are used to protect the internal foam layer and enhance the overall strength of the roof board.
- Polyurethane foam core layer: as the main thermal insulation material of roof slab, it has extremely low thermal conductivity and excellent thermal insulation performance. The thickness of 75mm ensures good thermal insulation effect.
- Strengthening ribs: 4-rib design, which means that there are four strengthening ribs inside the roof slab to improve its load-bearing capacity and wind resistance.
Application of PUF panel roof
The 75mm thick 4-rib PUF roof panel is widely used in various building fields that require thermal insulation, including but not limited to:
- Residential buildings: As a roof insulation layer, it improves the thermal insulation performance of residential buildings and reduces energy consumption.
- Industrial plant: used for the roof of industrial plants to ensure stable internal temperature and reduce energy consumption.
- Agricultural greenhouse: As the roof material of the greenhouse, it provides thermal insulation function while ensuring the lighting needs of crops.
- Cold chain logistics: In cold chain logistics facilities, it serves as insulation material for the roof of cold storage to ensure stable temperature of goods during storage.
Characteristics of a 75mm thick 4-rib PUF panel roof
- Excellent thermal insulation performance: polyurethane foam core layer has extremely low thermal conductivity, and 75mm thickness ensures good thermal insulation effect.
