The application of external wall insulation materials in Shandong has become an indispensable part of modern architectural design and construction. Shandong external wall insulation materials can reduce building energy consumption and improve residential suitability, while also enhancing the durability and protective performance of buildings.

At present, external wall insulation materials in Shandong are mainly divided into two categories: inorganic insulation materials and organic insulation materials. Inorganic thermal insulation materials are mainly rock wool, glass wool, silicate, etc., while organic thermal insulation materials are mainly polystyrene foam, polyurethane foam, polyurethane foam, etc.

Both inorganic and organic insulation materials need to pay attention to some issues during use. Firstly, the selection of building materials should comply with national standards and have good durability and fire resistance to ensure the security of the building. Secondly, attention should be paid to the construction process of external wall insulation materials to avoid violating the prescribed foundation treatment during the construction, bonding, and coating of wall insulation materials, which may cause the wall insulation materials to loosen, fall off, or crack and leak water.

From an environmental perspective, organic insulation materials have relatively poor environmental performance and are prone to releasing harmful substances, posing potential risks to the environment and human health. Inorganic insulation materials are considered a more environmentally friendly and healthy choice due to their small fiber fineness and high density, which can effectively insulate and reduce noise without generating chemical reactions.

In short, the application of external wall insulation materials in Shandong is of great significance for improving building energy efficiency and enhancing the living environment. In the process of selection and use, factors such as quality and environmental protection need to be considered, and national standards and regulations should be followed to ensure the security, environmental protection, and suitability of the building.
