Sandwich panels – characteristics, application and production

Sandwich panels are being talked about more and more. It is one of the materials with rapidly growing popularity, which is due to its very good technical parameters and their adaptation to the needs of current construction. Both individuals and investors are reaching for it, and in many different industries.

Sandwich panels – definition and characteristics

Sandwich panels are building materials used to enclose roofs (roof panels) and exterior and interior walls (wall panels). They consist of several essential elements: insulating core in the central part and metal cladding on its two sides.

They make it possible to compose the body of the building and provide the project with high thermal insulation, sound insulation and even fire resistance parameters. They are characterized by high mechanical resistance and long service life, even reaching several decades. Sandwich panels – for that is also the name they go by – are also very elegant and neat, so they find their way into even the most modern designs, and add a modernist look to simple developments.

A major advantage, contributing to the growing popularity of the sandwich panel, is that it fits the requirements of the sustainable building trend. Durable, thermally insulated, free of toxic gases and created using an increasing amount of renewable energy (as in Kingspan) meet the needs of investors who pay attention to the climate neutrality of the building being created.

What does production look like?

I. The process of creating each panel begins with the facings – profiling them according to the technical documentation and protecting them with a protective film for transportation. Such cladding is responsible for the mechanical resistance of the entire material and its aesthetic qualities.

II. The second step is to prepare the insulating core, the essential filler of the sandwich board. It is he who gives the material, among other things, a certain thermal insulation. The value of the parameters depends on what material is used in the core. Manufacturers usually choose mineral wool, polyurethane foam or polystyrene, although there are companies – such as Kingspan – where great emphasis is placed on developing proprietary cores with even higher values for key technical parameters.

III. Next comes the connection of the cladding to the core. This is a fully automated, in-line process that takes advantage of the ability of the plastics to bond to each other, the so-called adhesion capacity.

IV. In just a short while, the sandwich panel will be ready for shipment. It is still only necessary to cut the material into fragments of predetermined dimensions and direct the product to what is known as seasoning, a break during which it will gain the right temperature, pass quality control and be protected before transport to the customer.

Application, that is, where are layered panels used?

Among the places where insulated sandwich panels are most often used are logistics, office and retail centers, warehouse halls, auto repair shops, sports and performance facilities, cold and freezer rooms, as well as agricultural facilities.
