Requirement analysis
Product Analysis
Key Points of the Requirement
Define the insulation system (EPS, XPS, rock wool, phenolic foam boards, or insulation-decorative composite panels) with thermal conductivity (λ value), density, thickness, and fire classification (A1/A2 or B1) required by your market. Specify whether a complete system is needed—adhesive, anchors, base coat, mesh, and finish—or boards only, the climate zone performance expectation, and decorative finish requirements for composite panels.
Cost Structure Analysis
Raw bead, basalt fiber, or resin cost dominates, followed by foaming and board-production energy, fire-retardant additives, and facing layers (aluminum foil, mortar, or decorative coatings) for composite products. Rock wool carries higher freight cost per R-value due to density, and complete systems shift a meaningful share into anchors, mesh, and adhesive components.
Estimated Cost Range
Indicative factory pricing: EPS board $2.00–$8.00 per m²; XPS $4.00–$12.00 per m²; rock wool board $6.00–$18.00 per m²; insulation-decorative composite panels $15.00–$50.00 per m² depending on facing. Container-load volumes typically negotiate 10–20% discounts. Final quotations depend on density, fire rating, thickness, and system completeness.
Procurement Considerations
Prioritize manufacturers with third-party fire-classification certificates for the exact product (not the raw material) and λ-value and density verification on delivered batches. For system supply, request bond-strength aging data and anchor pull-out compatibility, and confirm all system components come as a tested assembly. Clarify dimensional tolerance, MOQ per thickness, export packaging (edge protection, palletizing), Incoterms, and delivery destination.
