With the increasing demand for indoor comfort and the popularization of energy conservation, external wall insulation materials have become an indispensable part of modern architecture. So, what is external wall insulation material? Why do we need it?

External wall insulation material refers to the insulation material applied to the surface of the external wall or packaged inside the external wall. Its main function is to isolate the temperature difference between indoors and outdoors, providing a more comfortable temperature environment for the interior of the building. At the same time, external wall insulation materials can also play a role in sound insulation, earthquake resistance, and other functions.

These insulation materials are mostly made of materials such as polystyrene, polyurethane, rock wool, glass wool, etc., and the insulation performance of these materials depends on their thermal conductivity. The lower the thermal conductivity, the better the insulation performance.

When choosing external wall insulation materials, we need to select suitable materials based on the actual situation. For example, if the building is located in an area with high climate temperatures, we can choose polystyrene insulation materials with lower thermal conductivity. In areas with lower climate temperatures, we need to choose materials such as rock wool with lower thermal conductivity.

In addition, we also need to consider the construction and maintenance costs of external wall insulation materials. Generally speaking, the construction of materials such as polystyrene is relatively simple and cost-effective, but due to the texture of their materials, they require frequent maintenance. The construction of materials such as rock wool is more complex, but their maintenance costs are relatively low.

It should be noted that choosing appropriate external wall insulation materials can not only provide a comfortable temperature environment indoors, but also reduce energy consumption, save energy, and help us build more environmentally friendly buildings.

Overall, external wall insulation materials are an indispensable part of modern architecture, and their performance and cost have their own advantages and disadvantages, which require us to consider comprehensively when choosing.
