JILIN VANKE CITY RESIDENTIAL PROJECT
Project Name: Jilin Vanke City Residential Project
Project Location: Erdao District, Changchun City, Jilin Province, China
Construction Year: 2010
Applied Products: High-density rock wool boards for exterior wall insulation, rock wool boards for roof insulation
Quantity Used: Approx. 85,000 m²
Application Area: Residential exterior wall insulation system, roof insulation system
Project Background
Jilin Vanke City is a key residential development project in Changchun with a large building scale, imposing strict requirements on the exterior insulation system:
-
Fire Safety: Exterior walls and roof insulation must achieve A1 non-combustible rating to ensure residents’ safety.
-
Thermal Insulation & Energy Saving: Maintain indoor temperature balance in severe cold climate, reducing heating energy consumption.
-
Durability & Stability: Rock wool boards must remain dimensionally stable, crack-free, and aging-resistant over long-term use.
-
Aesthetic & Environmental Friendly: Insulation system integrates with building aesthetics, ensuring a uniform and high-quality appearance while complying with green building standards.
✨ SUNTHERM Solution
-
Targeted Material Selection:
-
Exterior wall insulation: High-density rock wool boards (≥120kg/m³, A1 non-combustible, thermal conductivity ≤0.040 W/m·K) for combined fire resistance and insulation performance.
-
Roof insulation: Boards with suitable thickness and strength to ensure roof thermal performance and installation feasibility.
-
Installation Optimization:
-
Exterior wall boards combined with thin plaster finish for uniform and aesthetic appearance.
-
Wall boards fixed with adhesive + anchors to ensure long-term stability.
-
Critical areas double-layer staggered installation to minimize thermal bridges and improve sealing and insulation efficiency.
-
Project Management & Integration:
-
BIM digital construction management used to pre-plan board layout, improving precision and efficiency.
-
Installation strictly follows construction standards to ensure quality and safety.
