According to different use, pu sandwich panel can be divided into three types: wall panel, roof panel, cold room panel.Widely used in industrial and commercial buildings, cold storages, warehouses and prefab buildings.


Low thermal conductivity of pu sandwich panels with excellent thermal insulation properties, can greatly reduce the thickness of periphery of the building structure, which effectively increasing the interior area of the building.


Super flame retardation

Super flame retardation

The coefficient of thermal conductivity is 0.023w/(m•k), which ensures better thermal insulation efficiency. In practice, this effectively keeps the building absorbing heat and brings enormous economic benefits.


Great flame retardation and the complete removal of cold bridges (during the rafter installation), do help reduce heating bills.


BRD pu sandwich panels are the most durable thermal insulating material in the construction industry. Under the normal maintenance, its service life is the same with buildings.


100% of the material is recyclable and the panels are friendly to the environment at the production and disposal stages.
Easy and quick installation

Easy and quick installation

Compared with traditional thermal insulation methods, BRD use less material while the installation process is less time-consuming and labor-demanding leading to lower building costs.  

Technical parameters

Cold room panels with different thickness are applied for different temperature requirements.
Temperature range Thickness of cold room panel
0 ℃ - - 5 ℃ 75mm thick
-10 ℃ - -18 ℃ 100mm thick
-25 ℃ - -36 ℃ 150mm thick
-36 ℃ lower 200mm thick

Manufacturing technology

The classification of polyurethane sandwich panel by application. There are three application that the cold room panel, polyurethane sandwich wall panel, polyurethane sandwich roof panel(our roof panel is the three waves roof panel in general).

The classification of polyurethane sandwich panel by raw material. There are four kinds that polyurethane sandwich panel, rock wool sandwich panel, glass wool panel, EPS panel.

The type of roll coating. There are three kinds that galvanized steel sheet, stainless steel, aluminum magnesium manganese plate. The normal thickness of  galvanized steel sheet is 0.4-0.7mm, the stainless steel is 0.3-0.4mm, the third is 0.5-0.7mm, they all come from Tianjin or Shandong.


1, First of all, it must carry on the construction preparation before installation, include personnel, materials, etc. All will be well prepared.
2, Before the installation of polyurethane wall panel, it should check whether the verticality and levelness of metope purlin installation requirements, wall frame column vertical degree meets the requirement.
3, Before installation polyurethane wall panel, it should first mounting plate bottom water retaining plate and the bottom of the window to block water board, water retaining plate and wall frame beam connection with self tapping screw fixation.
4, Polyurethane wall panel links with ground. 
Lateral links: fixed polyurethane sandwich panel with the ground at the other end of the round hole with steel frame fixed, connection between the two plate mouth involution, if occurrence crack of the connectors available heat preservation to fill.
Vertical links: the gap between plates, using the dedicated button concave groove in the fixed polyurethane wall panel.
