Shandong exterior wall insulation material is a building material used for wall insulation, which plays a vital role in modern buildings. It can improve the thermal insulation and heat insulation of buildings, thereby saving energy, reducing indoor temperature, and reducing the use of air conditioning and heating.

Shandong exterior wall insulation materials come in many different types and materials, among which polystyrene (EPS), fiberglass mat (FG), mineral wool board and polyurethane foam (PUR) are commonly used. The thermal insulation properties of these materials vary, so when choosing the insulation material that suits you, you need to choose according to different situations.

Polystyrene EPS is a very cost-effective insulation material because of its light density, flexible shape, easy construction and low price. However, EPS also has some disadvantages, such as being susceptible to ultraviolet rays, easy to age and deteriorate, and the need to replace the insulation board.

Fiberglass mat FG is another common insulation material that has very good thermal insulation properties and can absorb sound. Fiberglass mat also has some disadvantages, such as dust is easily attached and irritating to workers' eyes and skin.

Mineral wool board is a more environmentally friendly insulation material because it is made of natural rock wool and does not release harmful gases. The thermal insulation performance of mineral wool board is also very excellent, and it can prevent fire and heat. However, because the mineral wool board is thick and difficult to install, it is necessary to pay attention to the construction and improve the construction quality.

Polyurethane foam PUR has excellent thermal insulation performance and can resist the penetration of hot and cold air and water vapor. In addition, PUR also has very good sound insulation performance, which can reduce the transmission of indoor and outdoor noise. However, PUR also has some disadvantages, such as being easily affected by sunlight and rain, and like EPS, the insulation board needs to be replaced.

Overall, Shandong exterior wall insulation material is one of the indispensable building materials in modern buildings, which can provide good thermal insulation and heat insulation performance for houses. The selection of suitable insulation materials needs to be evaluated according to different situations, and try to choose materials with high cost performance, good environmental protection and good thermal insulation performance.
