As people's requirements for living environment continue to increase, exterior wall insulation materials have become an indispensable part of modern residential buildings. In architectural design, suitable insulation materials can effectively improve the energy saving and living suitability of buildings. Let's take a look at Shandong exterior wall insulation materials and their related characteristics.

1. EPS insulation material

EPS insulation material is a polystyrene foam with excellent thermal insulation and sound insulation properties. Its low thermal conductivity makes it difficult for the temperature inside the building to dissipate, thereby greatly improving the energy saving of the building; at the same time, EPS insulation material can also absorb sound and reduce noise, providing residents with a quieter living environment. However, since EPS is flammable in the event of a fire, special fire prevention treatment is required.

2. XPS insulation material

XPS insulation material is made of polystyrene through a special process and has high thermal insulation and flame retardant properties. Compared with EPS, XPS is harder and more stable, has a longer service life and better compression resistance. However, XPS is more expensive than EPS, so it is not suitable for all projects.

3. Mineral wool board insulation material

Mineral wool board insulation material is made of mineral fiber and chemical fiber through special processing, and has good thermal insulation and sound insulation performance. Mineral wool board is an inorganic non-metallic insulation material that will not spontaneously combust, so it has high fire resistance. However, the service life of mineral wool board is relatively short and the price is relatively high.

4. Reinforced concrete external insulation system

Reinforced concrete external insulation system is a comprehensive insulation system, including insulation layer, anti-cracking protective layer, decorative surface layer and other components. Compared with traditional external insulation materials, reinforced concrete external insulation system has better thermal conductivity and durability, is not easily affected by the external environment, and has the dual functions of insulation and waterproofing. However, the cost of this insulation system is relatively high and requires good construction technology support.

In general, different types of insulation materials have their own advantages, and architects and homeowners need to choose suitable insulation materials according to the specific project conditions. At the same time, reasonable construction and maintenance are also important factors to ensure the thermal insulation performance of buildings.
