Polyurethane Carved Board

Jason Building Materials offers high-quality polyurethane carved panels suitable for buildings in regions characterized by low temperatures and significant diurnal temperature fluctuations.

The surface of the board is made with a precision metal embossing and baking paint process, and it is available in a variety of high-end styles such as stone, wood grain, and antique brick. At the same time, it is lightweight, has strong shock absorption and cushioning capabilities, and is suitable for extreme outdoor environments.

What is a Polyurethane Carved Board?

Polyurethane Carved Board is a premium prefabricated composite panel for exterior walls, featuring a core insulation layer made of high-density rigid polyurethane foam. It integrates multiple functions, such as thermal insulation, exterior decoration, protective shielding, and rapid installation. It is primarily used in applications including building facades, light-gauge steel villas, prefabricated structures, industrial facilities, and energy-efficiency retrofits for existing buildings.

As a three-layer composite material, it consists of the following components:

● Outer Layer: High-quality Al-Zn (aluminum-zinc) coated steel sheet, featuring various three-dimensional carved patterns created through intelligent embossing and lamination technologies.

● Core Layer: Rigid polyurethane. This is recognized globally in the construction industry as one of the best industrial thermal insulation materials, offering the lowest thermal conductivity and superior insulation performance.

● Inner Layer: A moisture-proof and radiation-resistant aluminum foil layer, designed to reflect heat and block moisture penetration.

Core Advantages

1. Closed cell rate ≥95%: After PU foaming, independent closed cells are formed. Air can hardly flow between cells, creating the best thermal insulation effect of a "static air layer."

2. Dimensional stability: Linear shrinkage rate ≤0.5% in the range of -30°C to 80°C, no cracking or deformation under thermal cycling.

3. Waterproof and breathable: The closed-cell structure prevents moisture from penetrating the core material, ensuring insulation performance does not degrade due to moisture over long-term use.

4. High bonding strength: The bonding force between PU and metal panel is about 0.15MPa, with no risk of interface separation between core and panel.

Technical Parameters

Core Material: High-density polyurethane (density 40-60kg/m³ optional)

Thermal Conductivity: 0.022-0.024W/m·K

Closed Cell Rate: ≥95%

Compressive Strength: ≥150kPa (at density 50kg/m³)

Water Absorption: ≤3% (volume ratio)

Flame Retardant Grade: B1 grade (flame retardant type)

Application Scenarios and Selection Recommendations

1. Light-gauge steel villas / Mobile homestays / Modular integrated housing:

Recommended configuration: 16mm/20mm thickness + PU core + Brick or wood grain finish.

Tips: Lightweight material reduces the load on the light-gauge steel framework; interlocking dry-installation allows for rapid assembly; wood and brick textures enhance the overall aesthetic appeal and premium look of the villa.

2. Industrial plants / Large-scale warehouse exterior walls:

Recommended configuration: 16mm/20mm/30mm thickness + Flame-retardant PU core + Large stucco or flat finish.

Tips: Flat or large stucco finishes provide a clean, impressive visual effect; selection should be based on local fire safety regulations.

3. Renovation / Retrofitting of older residential complexes:

Recommended configuration: 16mm/20mm thickness + Al-Zn alloy coated steel facing + Fluorocarbon (PVDF) coating.

Tips: Minimizes the load on existing wall structures; the highly weather-resistant PVDF coating prevents fading and cracking for up to 20 years, resulting in low long-term maintenance costs.

Samples and Testing

Polyurethane carved board sample types: Cross-section display block (200mm×200mm, showing three-layer structure of steel plate + PU core + aluminum foil backing); pattern sample (100mm×300mm, showing different patterns and colors).

Test reports available: Thermal conductivity test report (according to GB/T 10294), compressive strength test report (according to GB/T 8813), combustion performance test report (according to GB/T 8626).

Sample delivery cycle: In-stock patterns dispatched within 3 working days; custom patterns require color swatch confirmation first.

FAQ

Q: Is polyurethane carved board environmentally friendly?

A: PU itself is a polymer material with no formaldehyde added during production. The finished product meets TVOC emission standards, and third-party environmental test reports are available.

Q: Is there a big difference in fire performance between PU board and rock wool board?

A: Flame-retardant PU can reach B1 grade (difficult to ignite), but it is not a non-combustible material. When a project explicitly requires A grade fire protection, rock wool core carved boards must be selected.

Q: Can PU boards be dry-hung on walls?

A: Yes. It is recommended to use self-tapping screws to penetrate the board and fix it to the keel, with screw spacing of 300-400mm. When the board surface bears wind pressure load, the screw fixing point density must be determined through structural calculation.
