Beige polyurethane insulation panels are sandwich panels with a core insulation layer of polyurethane rigid foam (PU) and a flexible surface material (such as non-woven fabric or metal sheet) on the surface. Designed specifically for building exterior wall renovation, the beige exterior can be used directly as a finishing layer, combining insulation and decorative functions. They are applied through high-pressure spraying or prefabricated panels to form a continuous insulation system without thermal bridges, significantly improving building energy efficiency.

| Sound insulation | Excellent (closed-cell core structure reduces noise pollution) |
The core advantages of Beige PU Insulated Panels for Exterior Wall Renovation are:
1. Highly Effective Insulation
The thermal conductivity is as low as 0.016–0.024 W/(m·K), less than 50% of that of traditional materials (such as EPS and rock wool). A 2.5cm thick polyurethane wall provides approximately the same insulation as a 4cm thick EPS or a 38cm brick wall.
With a closed-cell ratio of >90%, it offers stable long-term thermal insulation performance (lifespan of 30–50 years).
2. Fire Safety
The addition of flame retardants achieves Class B1 fire resistance (difficult to burn and self-extinguishing). It does not melt or drip at high temperatures, and some products meet Class A standards.
3. Waterproof and Moisture-Proof
The hydrophobic structure resists mold formation even after 30 days of immersion, effectively preventing water seepage.
4. Lightweight and High-Strength
With a density of 35–40 kg/m³ and a compressive strength of 150–250 kg/m², it resists deformation.
5. Convenient Construction
Prefabricated panels allow for immediate installation, reducing on-site work; spray-coated versions are suitable for complex facades.
Beige PU Insulated Panels for Exterior Wall Renovation application scenarios and application cases
1. Building Exterior Renovation
Directly cover old walls to address insulation loss. The beige finish reduces secondary renovation costs.
2. Industrial Buildings
Factories and cold storage exteriors: Leverage its high sealing properties for moisture-proofing and thermal insulation, suitable for clean environments such as food processing plants and photovoltaic cell plants.
3. Special Locations
Areas with fire safety requirements (such as kitchen partitions) and high-humidity environments (around swimming pools)
