PU Sandwich Panels

PU Sandwich Panels

Specification

Taking polyurethane with excellent insulation performance as core material and colored steel sheet, the sandwich-type board can reduce the heat conduction due to difference between internal and external temperature to achieve maximum efficiency of freezing and refrigeration system

Advantage

SUPER FLAME RETARDATION
The coefficient of thermal conductivity is 0.019-0.023w/(m•k), which ensures better thermal insulation efficiency. In practice, this effectively keeps the building absorbing heat and brings enormous economic benefits.

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

DURABLE
TS 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.

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

EASY AND QUICK INSTALLATION
Compared with traditional thermal insulation methods, this uses less material while the installation process, it is less time-consuming and labor-demanding leading to lower building costs

PU Sandwich Panel Sizes and Types:

There are different types of PU sandwich which can be manufactured with both continuous and discontinues sandwich panel line:

Solar Roof Panels

Typical Size of Roof Sandwich Panel: 40, 50, 60, 70, 80, 90, 100, 120 mm

Duct Panel

Typical Size of Duct Panel Sandwich Panel: 20, 30 mm

Board Panel

Typical Size of Board Panel Sandwich Panel: 20, 30, 40, 50, 70, 100, 120, 150, 200 mm

Weight and Length of PU Sandwich Panel

The two factors which determine the sandwich panel weight are:

1. Thickness of skin, previously mentioned that the sheets could be PPGI (pre-painted galvanized iron, also known as pre-coated steel, coil coated steel, color coated steel coated by a hot dip zinc substrate), PPGL (pre-painted Galvalume iron, coated by a hot dip zinc substrate.

2. Density of PU foam produced by metering or foam machine in the sandwich panel production line. Length of sandwich panel produced by discontinues sandwich panel production depends on the usage requirements which could be minimum 2ft to 40ft long. Yet, sandwich panels are normally produced less than 20ft for easier transportation and avoiding over length cargo.
