Seoul Gangnam High-End Residential Complex Project

Project Name: Seoul Gangnam High-End Residential Complex
Location: Gangnam District, Seoul, South Korea
Construction Time: June 2024
Applied Product: SUNTHERM External Wall Rock Wool Board (110–130 kg/m³)
Quantity Used: Approx. 120,000 m²
Application Area: External wall insulation and fireproof barriers of high-rise residential buildings

▶ Project Background

Seoul has a temperate continental climate with harsh winters (down to –15℃) and hot, humid summers. This poses dual challenges for construction materials:

• Thermal Insulation & Energy Saving: reduce heating energy consumption in winter.

• Fire Safety: Korean regulations require non-combustible (Class A) materials for façades of high-rise buildings.

• Durability & Weather Resistance: cope with seasonal temperature fluctuations, monsoon humidity, and typhoon winds.

• Comfort: residents expect excellent sound insulation and indoor comfort.

✨ SUNTHERM Solution

1. Material Configuration

• High-performance SUNTHERM Rock Wool Board (120 kg/m³, λ ≤ 0.039 W/m·K).

• Class A non-combustibility, fire resistance over 1000℃.

• Excellent sound insulation (≥50 dB), ensuring quiet living in dense urban areas.

2. Construction Method

• Curtain wall system with adhesive & anchor fixing, ensuring stability for high-rise façades under strong winds.

• Layered installation: low-density board inside for insulation, high-density board outside for compression resistance and weather protection.

• Combined with breathable waterproof membranes for monsoon season protection.

3. Sustainability

• Certified by Korean KS Standard & ISO14001 Environmental Management.

• Recyclable, supporting Seoul’s green building policies.

✅ Project Results

• Energy Saving: reduced annual energy consumption by ~18%.

• Fire Safety: fully compliant with Korean fire codes.

• Comfort: superior thermal & acoustic performance.

• Market Impact: one of the first landmark residential projects in Seoul using Chinese-made high-performance rock wool.

★ Project Summary

The Seoul Gangnam project demonstrates the advantages of SUNTHERM Rock Wool Boards in the East Asian high-end residential market:

• Outstanding thermal insulation, fire resistance, moisture control, and sound insulation;

• Compliance with Korean construction codes and environmental standards;

• Improved comfort and durability, highly praised by both developers and residents.

This project has become a benchmark reference for SUNTHERM in the East Asian market, laying a strong foundation for expansion into Korea, Japan, and Mongolia.
