What is PU Sandwich Panel

Introduction of PU sandwich panels

A sandwich panel is any structure made of three layers: a low-density core, and a thin skin-layer bonded to
each side. Sandwich panels are used in applications where a combination of high structural rigidity and low
weight is required.

The pu sandwich panel consists of a panel of three different layers of material.

The first layer: Al-zn alloy coated steel plate

Second layer: PU foam

The third layer: aluminum foil paper

The PU sandwich panel is easy to install, lightweight and efficient. The filling system also uses a closed-cell molecular structure to prevent
condensation of water vapor.

Its main use is in the large industrial construction industry. Such as cold storage, large stadiums, hospitals, old building renovations,
schools, libraries, residential and so on.

Advantages of PU sandwich panels

Lightweight: Since most of the volume is a layer of foam, the density of the foam is very small. The weight of the entire sandwich panel

is not as heavy as a panel of the same size.

Fire protection: This is a major feature of sandwich panels. Because most of its materials are non-combustible and difficult to burn materials,
it can meet the requirements of house exterior wall fire protection.

Customized appearance: The outer surface of the sandwich panel is customizable in pattern and color. This feature can be used with a variety
of groups to decorate the exterior of the house.

Insulation performance: Commonly used core materials are RW, PF, PU, XPS, eps. The special properties of these materials can ensure the
insulation performance of the building.

Anti-noise: The core board can prevent noise from reaching 40-60 decibels. Can provide a quiet environment.

Easy to install: The sandwich panel has a simple structure and lightweight, and is equipped with a chain interface. A worker can install about
50 square meters a day.
