The 3ribs PU/PUR/PIR roof sandwich panel use polyurethane as the core material and have metal plates on both the upper and lower sides. They have good thermal insulation, waterproof performance and relatively high strength. They are easy to install and are widely used in the roofs of industrial plants, warehouses, commercial buildings, etc., which can effectively improve the energy - saving and comfort of buildings.
Product Highlights
Low thermal conductivity, energy saving & stable temp
Triple-rib structure high strength anti-deformation
Special lap design reliable waterproof performance
Flame-retardant PU core self-extinguishes off fire
Versatile for factory, warehouse & commercial roofs
The 3ribs PU/PUR/PIR roof sandwich panel use PU (polyurethane), PUR (polyurea) or PIR (polyisocyanurate) as the core material, which is sandwiched between two layers of metal plates on the top and bottom. Among them, the unique three - rib (3ribs) structural design enables the panels to have better performance in roof applications.
For example, in industrial plants in cold regions, the outside temperature is extremely low in winter, and traditional roof materials may cause a large amount of heat loss inside the plants. However, this kind of sandwich panel can effectively prevent heat conduction, so that the plants can maintain a suitable working temperature without continuous high - power heating, which greatly reduces the energy consumption cost.
In the hot summer, for commercial buildings such as large supermarkets, under the intense sunlight, it is very difficult for the outside heat to pass through the sandwich panel into the interior, reducing the cooling load of air - conditioning, which is helpful for energy conservation and emission reduction.
At the same time,PU/PUR/PIR has high hardness and is a flame - retardant material that self - extinguishes when leaving the fire. Using polyurethane roof sandwich panels can help you improve the usage environment of plants and warehouses.
