Rock Wool Board: Thermal conductivity of 0.041–0.045 W/(m·K); fire-resistant and flame-retardant, but exhibits high moisture absorption and relatively poor thermal insulation performance.
Glass Wool: Simple to install and can be cut to size with ease. Features antibacterial and anti-mold properties, as well as resistance to aging and corrosion, thereby ensuring a healthy indoor environment. Characterized by low moisture absorption and stable physical properties.
Expanded Polystyrene (EPS) Board: Thermal conductivity of 0.037–0.041 W/(m·K); offers good thermal insulation and is cost-effective, though its mechanical strength is relatively low.
Extruded Polystyrene (XPS) Board: Thermal conductivity of 0.028–0.03 W/(m·K); provides superior thermal insulation and high mechanical strength, and is highly resistant to moisture. However, it is more expensive than EPS and requires surface treatment during installation.
Polymer-Modified Polystyrene Bead Insulation Mortar: Thermal conductivity of 0.057–0.06 W/(m·K); features good flame retardancy and is recyclable. However, its thermal insulation performance is less than ideal, and it imposes strict requirements on the installation process.
