In many areas, because the temperature is relatively low in winter, in addition to good indoor warmth measures, suitable exterior wall decorative insulation boards can also play a significant thermal insulation effect. Different from air conditioners, the application of external wall insulation materials has obvious energy-saving and emission-reduction effects, so it has received the attention of the country. External wall thermal insulation decorative panel is an industrially produced large-format hanging wall panel, which integrates the external wall thermal insulation function and the external wall decoration function, and is installed on the outer surface of the building on site.

So, what are the functions of the exterior wall decorative insulation board? Next, I will introduce it in detail:

1. Different types of materials have different thermal conductivity; different performance exterior wall decorative insulation boards require different insulation layer thicknesses to meet the designed thermal resistance requirements; the same material, different bulk density, and different maturity coefficients. The higher the porosity of the data and the more pores, the lower the thermal conductivity and the better the thermal insulation performance. The thermal conductivity is different for different water-containing conditions. It must have good thermal insulation performance to ensure that the heat is conducted to the room in one direction. The external wall decorative thermal insulation board with good thermal insulation effect can prevent heat from being transmitted to the floor and lost to neighbors. The factors that affect the thermal conductivity of the material are the material, porosity, wetness level of the penalty state and ambient temperature.

2. It must have good flame retardant properties and. The temperature of the heat medium reaches 45-60 degrees Celsius. If the insulation layer is in contact with the heating pipe, organic materials will volatilize toxic or odorous gases, which is not good for human health. This is the difference from exterior wall or roof insulation materials. Therefore, composite materials with good thermal insulation function and flame retardancy will be the direction of development.

3. The thermal insulation decorative board must have a high resistance to deformation under pressure. If the external wall decorative insulation board does not have sufficient load-bearing capacity, the insulation layer has to accept the excitation from the heating pipe, the concrete filling layer and the active load on the floor and the floor, and it will deform due to uneven compression, resulting in the concrete filling layer and the floor. Cracks occur, or the heating pipes are abnormally displayed at a higher temperature and the service life is reduced. Because foamed cement has higher pressure resistance, it is recommended to use foamed cement in large-area applications. The external wall thermal insulation decorative board must have performance in order to achieve the effect we want. The above content is a summary of the functions of the external wall decorative thermal insulation board for everyone. I hope it will be helpful to you.
