Project Address: Kangjiayuan, Chaoyang District, Beijing
Project Type: Phase II External Wall Insulation Project of Kangjiayuan New Development, Supporting Insulation Works for New Residential Buildings
Project Scale: The total coverage area of rock wool boards is approximately 46,000 ㎡
Project Introduction:
Phase II of Kangjiayuan New Development in Chaoyang District, Beijing consists of newly-built residential building clusters. Planned and constructed in strict accordance with current building energy-saving design standards and fire protection codes, the project imposes stringent requirements on fire resistance, tensile strength and thermal stability of external wall insulation materials. All rock wool boards adopted for the external wall insulation system of this project are supplied by Langfang Haochen Insulation Material Co., Ltd. Multiple thickness specifications are provided to meet energy-saving design requirements of different facade zones, ensuring high-standard construction and implementation of the whole external wall insulation system.
II. Application Details of Insulation Materials
Supplier: Langfang Haochen Insulation Material Co., Ltd.
External Wall Insulation System
Main Material: 140kg/m³ rock wool boards
Specification List:
140kg/m³, 1200×600×80mm
140kg/m³, 1200×600×100mm
140kg/m³, 1200×600×50mm
III. Core Advantages of Product Selection
Grade A Non-combustible Material, Meeting Fire Code Requirements for New Residential Buildings
The 140kg/m³ rock wool boards are Grade A non-combustible inorganic insulation material with stable and reliable fire resistance performance, which can effectively block flame spread, comply with relevant fire protection specifications for external wall insulation of new residential buildings and build a solid safety barrier for building fire prevention.
Matched Multi-thickness Specifications to Satisfy Differentiated Building Energy-saving Design
Based on energy-saving indicators of different orientations and positions of building blocks, three types of 140kg/m³ rock wool boards in 50mm, 80mm and 100mm thickness are laid in different zones. Featuring excellent tensile strength, the boards adapt to construction techniques of external thermal insulation composite system. They can resist long-term outdoor temperature variation and rain erosion, lowering risks of hollowing and falling off in later service stage.
Excellent Thermal Insulation Performance for Long-term Building Energy Conservation
Rock wool boards have low thermal conductivity and stable long-lasting heat preservation effect, which can effectively block heat exchange between indoor and outdoor spaces, stabilise indoor temperature, reduce heating and cooling consumption of buildings and satisfy energy-saving design indicators of new residential buildings.
Standard Dimensions for Convenient On-site Cutting and Installation
With unified standard size of 1200×600mm and flexible multi-thickness selection, rock wool boards can be cut flexibly for facade modelling, door and window openings and other structural nodes to reduce material loss, improve external wall construction efficiency and guarantee project progress.
IV. Project Cooperation Highlights
✅ Supply of three thickness options of 140kg/m³ rock wool boards as per construction drawings, simultaneous delivery of multiple specifications to satisfy thermal insulation structural design demands of different areas;
✅ Total supply area of approximately 46,000 ㎡. The original manufacturer arranges production scientifically and delivers goods in batches to match phased construction schedule of Phase II project;
✅ Each batch of boards comes with product certificates and third-party test reports. Complete documents facilitate smooth material inspection on site and filing work;
✅ Factory technicians cooperate with construction teams and provide professional construction guidance for key nodes such as internal and external corners and surrounding areas of doors and windows.
V. Project Summary
The Phase II external wall insulation project of Kangjiayuan New Development in Chaoyang District, Beijing adopts multi-specification 140kg/m³ rock wool boards for the external wall insulation system. Upon completion, the fire safety rating and thermal insulation performance of the building external wall meet design standards, effectively cutting building energy consumption and improving living comfort of the residential community.
This project fully verifies the multi-specification product system of Langfang Haochen 140kg/m³ rock wool boards. It is applicable to external wall insulation projects of newly built residential buildings and serves as premium material option for fireproof and thermal insulation systems of new building external walls.
