Introduction

One of the effective prefab house materials trending in the field of engineering is the sandwich panel. It is produced in various types with each of them manufactured for specific industrial and residential applications. Basically, all sandwich panels are manufactured with more than one material with each compatible for thermal insulation.

For example, rockwool sandwich panels are designed specifically for users who deal with a fire at home or in their line of business. This is because it is non-combustible. On the other expanded polystyrene sandwich panel (PU sandwich panel) is designed to reconcile the extremity of hot or cold temperatures. However, there is still a gap for a product that is a perfect and suitable sandwich panel for users whose uses and application fall under freezing or cold category.

It has been found that manufacturers have produced PU Sandwich Panel to fill this gap. This study guide is quality research produced to guide potentials users of PU Sandwich Panel on the basic things to know. It is segmented into chapters for a sound comprehension by readers.

Chapter One: What is PU Sandwich Panel?

Figure 1: PU Sandwich Panel

The term “PU” is an abbreviation for polyurethane. A polymeric resins that compose contents that are urethane which is a white crystalline organic compound (ethyl-carbamate). In the process of manufacturing, polyurethane is injected into other secondary materials such as double-dyed galvanized steel sheet, stainless steel, and aluminum magnesium manganese.

The end result of this combination is a polyurethane sandwich panel which is used to beautify a house and also to guarantee a high thermal insulation performance in a building.  In terms of insulation, PU sandwich panel is superior to other types of the sandwich panel because of its lambda measures at 0.022 (W/MK). The Coil Coating technology used to paint PU Sandwich Panel ensures that the skin of the panel is corrosion-resistant. PU Sandwich Panel finds its application either as the whole fabric of a building or as a part of the building which is usually the roof, the wall, the facade, or the floor. Its water-friendly external layer makes it perfect for cleaning when it is used on floors. PU Sandwich Panel is also color-friendly as it gives painting the radiance and longevity required for quality aesthetics.
