PU Insulation Board
It is a high-performance ventilation duct product, which is widely used in HVAC systems. The following is a detailed introduction:
Basic Structure: It is a sandwich structured panel. The core is Polyurethane(PU) foam, which is a closed-cell insulating material. The two outer layers are aluminum sheets or aluminum foils.
Panel Structure: Silver Alu. Foil/ PU Foam/ Silver Alu. Foil
Foam Density: 50kg/CBM
Panel Dimension: 3950mm*1200mm*20mm
Alu. Foil: 60 or 80 Micron (Embossed)
Fire Rating: Class 0 (BS476Part 6&7)

Main Production Process of PU Insulation Board








spatial economics of PU Insulation Board

Traditional insulation materials require a relatively thick size to meet the standards, while PU insulation boards, with their extremely low thermal conductivity, can reduce their thickness by 30% to 50% under the same insulation effect.
A case study of a community housing project in Germany shows that its slim profile enables the exterior wall structure to be slimmed down, ultimately adding three additional living Spaces for apartments and directly enhancing the economic benefits of the project.
For industrial plants and cold storage facilities, reducing the space occupied by walls can optimize the layout of equipment or the storage capacity of goods, indirectly lowering the operating cost per unit area.
From a full life cycle perspective of PU Insulation Board
The production end relies on an automated continuous production line, with precise raw material proportioning and thickness tolerance controlled within ±1mm, reducing material waste.
During use, the water absorption rate is less than 2%, moisture-proof and anti-aging, avoiding secondary maintenance and replacement due to performance degradation, and extending the service life of the building insulation system.
The end supports recycling and reuse, which is in line with the concept of circular economy and is different from the environmental shortcoming of some traditional insulation materials that are difficult to degrade.

Perspective of technological iteration of PU Insulation Board

By modifying the chemical molecular structure and introducing N.P heterocyclic compounds, the migration problem of flame retardants in traditional products is solved, achieving a long-lasting and non-diminishing flame retardant effect.
High-temperature molding technology makes the product structure more stable, avoiding shrinkage and deformation during use, and its dimensional stability far exceeds that of traditional PU materials.
Some high-end products have a compressive strength of over 400kPa, and their bonding strength meets the technical regulations for external wall insulation engineering, taking into account both insulation and structural safety.
