FM Approved Sandwich Panel

———

Sandwich panels consist of two outer layers and a core material, which can be made from a variety of materials, including PU/PIR foam, EPS, or rock wool, glass wool. One of the primary advantage of sandwich panels is their insulation properties helping to reduce energy costs and improve thermal efficiency in buildings. Another advantage of sandwich panels is their ease of installation. They can be prefabricated off-site, reducing construction time and costs. Additionally, sandwich panels are easy to handle and transport, making them ideal for remote or hard-to-reach locations.
Sandwich panels are commonly used building material used in industrial facilities, commercial buildings, cold storages, residential buildings as well as buildings for agricultural and husbandry. Depending on different core materials, RPIC offer PU/PIR sandwich panel, Rockwool and Glasswool sandwich panel and EPS sandwich panel for your choice.

Efficient Contruction: Sandwich panel provide easy installation which can be triple faster than usual  concrete  building. It can also has less affection from weather during construction. It allows large span, the supporting  structure can be lighter.

Perfect Energy Saving  :  Sandwich panels provides high thermal insulation by means of PUR, PIR, EPS and Mineral Wool insulation materials. It has lower U value and higher insulation capability .

Environmental Friendly:  Sandwich panels require less maintenance than concrete an brick structure; repainting  is not required. It is more economical and environmental friendly.

Safe, Durable and Reusable:  Sandwich panels are light weight that are easy and safe to handle during con- struction. Also can be easy assembly and disassembly.

Versatility:  Sandwich panel can be used for various applications, such as pre-fabricated steel buildings , warehouse, walk-in cold storgaes, cleanroom, farm, food processing plant and etc.

Benefit and Value:  Compare with traditional construction, sandwich panel are more economical in terms of labours,machines,time, maintenance.cost etc. It enables big saving in future operation costs.
