Customization of Insulation Boards for Prefabricated Houses

The customization of insulation boards for prefabricated houses requires a comprehensive selection based on material, performance requirements, and budget. Below are specific plans and suggestions:

I. Core Customization Options and Parameters

1. Lightweight EPS Cement Prefabricated Insulated Sandwich Wall Panels

   • Material: EPS cement (expanded polystyrene + cement + sand + admixtures), featuring waterproof, flame-retardant, and 4-hour fire resistance properties, and lightweight for easy installation.
   • Specifications: Thickness 60-150MM (customizable), length 2270/2440mm, suitable for internal and external walls, floors, and roofs of villas and warehouse residences.
   • Price: Unit price of 65.43 yuan/square meter for bulk purchases (≥5000 square meters), sample price of 66.09 yuan/square meter.
   • Advantages: High fire resistance rating, suitable for scenarios with strict safety requirements, and supports thickness customization.

2. Cement Prefabricated Insulation Boards

   • Brands: Xingbojun, Qigong, Boting, etc., available in square, rectangular, and panel shapes.
   • Price: 8-39.9 yuan/square meter or piece (e.g., 39.9 yuan/square meter in Dongguan, Guangdong; 15 yuan/piece in Suihua, Heilongjiang).
   • Suitable Scenarios: Basic insulation needs with limited budget and low fire resistance requirements.

3. XPS Extruded Polystyrene Boards

   • Performance: Closed-cell structure with a thermal conductivity of 0.028, suitable for flat cement roofs; when purchasing, focus on thermal conductivity < 0.03 and fire rating B1; for rainy areas, consider options with aluminum foil.
   • Advantages: High cost-effectiveness, but configuration adjustments are needed based on climate conditions.

4. Lightweight Insulated Partition Wall Panels

   • Materials: Phenolic panels, magnesium oxide panels, calcium silicate panels, etc., priced at 25-75 yuan/square meter (e.g., 35 yuan/square meter for phenolic panels from Langfang Kelier, 75 yuan/square meter for calcium silicate panels from Dacheng Aowei).
   • Suitable Scenarios: Walls or roofs with special material requirements (e.g., corrosion resistance, high strength).

II. Customization Suggestions

1. Clarify Demand Priorities:

   • For roof insulation boards requiring fire resistance, waterproofing, and lightweight properties, prioritize EPS cement sandwich panels and confirm whether the supplier supports thickness/size customization.
   • For limited budgets, XPS extruded polystyrene boards or cement prefabricated panels (e.g., from the Xingbojun brand) can provide basic insulation functions at a lower cost.

2. Confirm Key Parameters:

   • Application Scenarios: For roofs, focus on waterproofing, load-bearing capacity, and thermal conductivity; for walls, consider fire resistance rating and ease of installation.
   • Size Customization: Some suppliers (e.g., Xiamen Zhongjingtai) support length and thickness adjustments, and production cycles need to be communicated in advance.
   • Fire Resistance Rating: For public buildings or high-rise residences, it is recommended to choose materials with a fire rating of B1 or above.

3. Supplier Communication:

   • Directly contact suppliers (e.g., Xiamen Zhongjingtai, Guangdong Youmei Building Materials) to confirm details, including minimum order quantity, delivery time, and after-sales service.
   • Request sample testing to verify whether the actual performance meets expectations.

Summary: The customization of insulation boards for prefabricated houses requires balancing performance, cost, and scenario requirements. Prioritize suppliers that meet fire and waterproof standards and support customization, and reduce risks through sample testing.
