PIR/PU Sandwich Great Wall Panel
PIR/PU sandwich Great Wall board is a new type of composite building material that integrates “decorative aesthetics + thermal insulation and energy conservation”. It is named for the uneven and staggered “Great Wall crenellations” texture on its surface. It not only retains the three-dimensional decorative texture but also possesses the highly efficient thermal insulation and sound insulation performance of PIR/PU core materials. It is widely used in scenarios such as exterior wall decoration of buildings, interior background walls, exhibition hall enclosures, and exterior walls of industrial plants, and is compatible with various design styles including modern simplicity and new Chinese style.

Q1：Versatile Aesthetic Adaptability for Diverse Styles
A:Three-dimensional textures and customizable colors deliver standout visual appeal, seamlessly adapting to modern minimalist, new Chinese, industrial, and various other design styles. Whether enhancing the grand facade of commercial complexes or the refined ambiance of hotel lobby feature walls, the product achieves precise aesthetic expression, eliminating the visual monotony of traditional flat panels.
Weather-Resistant Coating & Stable Color for Long-Lasting Appeal
The surface resists fading and peeling even under prolonged exposure to UV rays and rain, addressing common issues like cracking in conventional exterior coatings or tile detachment. This ensures the building’s exterior maintains a “like-new” appearance over time, reducing long-term maintenance and refurbishment costs.
Q2: Dual Advantages in Thermal Insulation & Soundproofing
A:High-Efficiency Thermal Insulation, Lower Energy Costs.When applied to exterior walls, the product helps reduce air conditioning and heating energy consumption by 15%–25%. Its insulation performance remains stable even in humid southern regions, resisting moisture absorption and ensuring sustained energy savings.
Noise Reduction for Improved Spatial Comfort
Effectively dampens external noise such as traffic and crowd sounds, while also minimizing indoor echoes (e.g., in conference rooms or exhibition halls). Creates a quiet and comfortable environment, making it suitable for residential, educational, healthcare, and other noise-sensitive settings.
Q3: Structurally Durable & Adaptable to Demanding Environments
A:High-Strength Impact Resistance
Withstands installation loads and daily impacts while offering a wind pressure resistance rating of ≥±4kPa. Suitable for mid- to low-altitude exterior applications, it resists strong winds without panel damage, overcoming the low impact resistance of traditional decorative panels and reducing maintenance needs.
Moisture & Corrosion Resistance for Extended Lifespan
A composite moisture-proof backing prevents mold and deformation, while the anti-corrosion coating offers protection against acid rain and high-humidity conditions. The product’s overall service life reaches ≥15 years, delivering lower long-term cost of ownership.
