The core comparison of commonly used insulation materials for self built houses in rural areas of Shandong Province, combined with the local cold climate, rural construction scenarios, and cost-effectiveness requirements, is carried out from the dimensions of key performance, cost, and adaptation scenarios to help you quickly select suitable materials.

???? Comparison of core performance parameters

Table

Material name Thermal conductivity (W/(m · K)) Fire rating Moisture resistance Service life

Molded polystyrene board (EPS) 0.039-0.041 B1 level flame retardant, average, long-term water immersion performance decreases by 20-25 years

Extruded polystyrene board (XPS) 0.028-0.030 B1 level flame retardant excellent, almost non absorbent for 25-30 years

Rock wool board 0.040-0.045 Class A non combustible general, requiring hydrophobic treatment for more than 25 years

Polyurethane rigid foam 0.022-0.027 B1 level flame retardant excellent, with waterproof properties for more than 30 years

Perlite particles 0.070-0.100 Class A non combustible, easy to absorb water for about 20 years

???? Comparison of Cost and Construction Difficulty

EPS board: The material unit price is about 30-50 yuan/square meter, and the construction difficulty is low. Ordinary bricklayers can operate it, making it a cost-effective first choice for large-scale use of exterior walls in rural self built houses.

XPS board: The material unit price is about 50-70 yuan/㎡, and the texture is hard and cutting is slightly laborious. It is suitable for damp and heavy load areas such as roofs and floors.

Rock wool board: The unit price of the material is about 60-90 yuan/㎡. During construction, it is prone to falling debris and irritating the skin, requiring professional personnel to operate. It is suitable for local areas with high fire prevention requirements.

Polyurethane rigid foam: The unit price of the material is about 80-120 yuan/square meter, and on-site spraying equipment is required for operation. The overall seamless and non thermal bridge insulation effect is optimal.

Perlite particles: The material unit price is about 20-30 yuan/㎡, suitable for filling irregular roofs, with limited insulation performance, and needs to be used in conjunction with other insulation layers.

???? Comparison of Adaptability to Rural Scenarios in Shandong Province

External wall insulation: EPS board is preferred as it has the highest cost-effectiveness, with a thickness of 8-10mm to meet the energy-saving requirements of cold regions in Shandong. It is equipped with anti cracking treatment of mesh cloth, which is mature in construction and not prone to problems.

Roof insulation: Priority should be given to polyurethane rigid foam or XPS board, which has good waterproof and moisture-proof performance and is suitable for the rainy summer and large temperature difference winter climate in Shandong, to avoid insulation layer failure due to water ingress.

Surrounding kitchen/boiler room: A-level fireproof rock wool board must be selected to avoid fire hazards in rural open flame usage scenarios.

Old house renovation with limited budget: EPS board can be used for external wall and internal insulation, construction is not affected by weather, and there is no need to change the external wall decoration, resulting in lower costs.
