Sandwich Panels

According to different core material, we offer Pur / 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.

Sandwich Panel Production Process

Strict Quality Control

Sandwich Panel Testing Equipment

With the exception of introducing the full set of Germany production line, relevant sandwich panel testing equipment are timely purchased in. Following parameter can be tested in the laboratory.

> mechanical performance of sandwich panels

> close-cell rate of foams

> fire resistance of foams

> heat transfer coefficient of foams

> stability of product dimensions all production are in strict accordance with current quality control standard in Europe.

Rock Wool Sandwich Panel

> steel sheets are produced by  color-coated line(introduced from Nippon Steel), performances of which are all conforming with European standard.

> Foam mateirals are supplied by the world top four PUR suppliers such as Bayer, DOW, Huntsman and BASF.Sunscape has also established long-term cooperative mechanism with them to make efforts for the development of PUR sandwich panels.
