The thermal panel for the façade is a complex and monolithic structure. It consists of an insulation plate (polyurethane foam (XPS), expanded polystyrene (PSB-S, EPS, PPS).
The outer finishing layer can be represented by different materials. You also need glue for a unique connection between the insulation layer and the protective and decorative coating.
The process of gluing two materials occurs by pressing the tile on the insulation panel using a single-component polyurethane. Glue, which unites the structure of both materials along the entire thickness, creating a monolithic and durable structure: decorative ceramics + insulation = thermal panel. An adhesive mixture cannot provide a more reliable connection of two materials without the use of an additional pressure load with a penetrating effect on the structure of the materials to be glued.
Our company uses two main types of insulating materials:
- Expanded polystyrene foam (EPS)
- Extruded Polystyrene Foam (XPS)
To choose the most durable and highest quality material, you will need to familiarize yourself in more detail with the characteristics of each of them.
Expanded polystyrene foam (EPS)
Extruded Polystyrene Foam (XPS)
Polystyrene is a popular insulating material, which is distinguished by the presence of a gas-filled structure. This polymer is made up of granules that have been obtained from the refining of petroleum. The process of producing the material involves the use of an additional method of expansion and sintering of all granules that are filled with air masses. Therefore, its volume increases 50 times.
If we compare expanded polystyrene foam with another popular insulation: mineral wool, we can notice the lower weight of the first material, its mechanical strength and the minimum coefficient of thermal conductivity.
Due to its low weight, the insulation layer provides the simplest possible way of fixing to vertical surfaces and also removes additional stress on all support structures.
Extruded polystyrene foam is considered a modern polymer, which is characterized by excellent thermal insulation and water-repellent properties. As the main raw material, special polystyrene granules are used, which are exposed to high temperatures, which "forces" them to melt.
Together with the expansion agent, the granules create a homogeneous mass, which is then extruded through the extruder, creating a continuous ribbon. When the material is completely solidified, it is cut into slabs of all sizes.
Such expanded polystyrene is also characterized by minimal weight, frost resistance, has a minimum level of water absorption, and does not lend itself to the attack of fungi or molds. Due to its structure, it is a completely safe and environmentally friendly material that does not pose any danger to the environment.
