Sandwich panels have rapidly conquered the construction market and today are among the most in-demand materials.

So what criteria should you consider when using these panels in construction?

So, having learned all the advantages of the material, you have settled your choice on sandwich panels. First of all, keep in mind that only a properly chosen, high-quality panel will deliver all its expected benefits — short installation time, thermal insulation, lightweight structure and more. When choosing, it is essential to pay attention to several key criteria.

The facing is the most important factor and combines several base materials. The most commonly used facing materials are gypsum, metal and moisture-resistant board. For residential buildings, SIP panels made of OSB boards and rigid polystyrene are recommended.

The core filler is one of the key components of the material. Usually a self-extinguishing expanded polystyrene is chosen. This material does not let moisture through, is breathable, highly fire-resistant, rigid and durable. This type of core is used for ceilings, walls and roofs.

The surface texture of the panels can be smooth or embossed, imitating stone, wood and other finishes. Such texture helps increase the panel's durability, resisting mechanical impact, temperature fluctuations and moisture.

And finally, the colour of the sandwich panel is also of particular importance. Colours are assigned according to the RAL catalogue codes. A panel chosen in the right colour in advance will save time and money at the final painting stage of construction.
