Exterior wall insulation material is a type of building material used for thermal insulation of building exterior walls, which can effectively reduce the energy consumption of buildings and improve energy utilization efficiency. Common external wall insulation materials include the following:

Polystyrene (EPS): EPS is a lightweight, low thermal conductivity insulation material widely used for exterior wall insulation. EPS has the characteristics of good thermal insulation performance, compressive strength, and low water absorption rate.

Polyurethane (PU): Polyurethane is a material with high insulation performance and low thermal conductivity. Polyurethane exterior wall insulation materials have good waterproof, fireproof, and sound insulation properties, and are suitable for various climatic conditions.

Rock wool: Rock wool is a natural mineral fiber material with excellent insulation, sound absorption, and fire resistance properties. Rock wool exterior wall insulation board is suitable for high-rise buildings, industrial buildings and other scenarios.

Fiberglass (GW): Fiberglass is a lightweight, high-strength insulation material with excellent thermal insulation, impact resistance, and corrosion resistance. Fiberglass exterior wall insulation board is suitable for residential buildings, public buildings and other scenarios.

Expanded perlite: Expanded perlite is a natural mineral material that, after high-temperature expansion treatment, has the characteristics of lightweight, porous, and low thermal conductivity. Expanded perlite exterior wall insulation board has good thermal insulation, moisture absorption, and fire resistance properties.

Rubber powder polystyrene particles: Rubber powder polystyrene particles are a type of insulation material composed of a mixture of polystyrene particles and adhesive. This material has good thermal insulation, impact resistance, and construction performance.

In short, there are various types of external wall insulation materials, including polystyrene, polyurethane, rock wool, glass fiber, expanded perlite, and adhesive polystyrene particles. When selecting external wall insulation materials, comprehensive consideration should be given to factors such as the specific needs of the building, climate conditions, and budget.
