Q1: What are the main benefits of concealed-fastener Polyurethane (PU) sandwich panels?
A1: These panels offer superior thermal insulation (with a conductivity of ≤ 0.023 W/m·K), high structural integrity, excellent airtightness, and versatile design options. The concealed fastener system protects the joint system from moisture and creates a clean, modern aesthetic with no visible screws.
Q2: What surface finishes and profile patterns are available?
A2: You can choose from four distinct surface finishes: Flat (pure flat), Mini-rib (small corrugated), Beaded (beading), and Embossed. Additionally, narrow-joint and wide-joint profiles are available to match different architectural styles.
Q3: In what thicknesses do you provide these panels?
A3: The panels are available in standard thicknesses of 50 mm, 75 mm, and 100 mm to meet varied thermal performance requirements. The exterior metal sheet thickness typically ranges from 0.4 mm to 0.8 mm.
Q4: Are the PU sandwich panels suitable for cold storage facilities?
A4: Yes, their extremely low thermal conductivity makes them highly effective for temperature-controlled environments, including cold storage, freezers, food processing plants, and climate-sensitive warehouses.
Q5: How do the panels perform under harsh weather conditions?
A5: The outer coated metal sheets provide high resistance to corrosion, impact, and UV degradation. The airtight sealing design prevents water infiltration and thermal bridging, ensuring reliable performance in temperature ranges from -50℃ to 150℃.
Q6: What is the standard effective coverage width of the panels?
A6: The standard effective coverage width is 1000 mm, which makes project planning, handling, and installation highly efficient. Custom lengths can also be configured according to project specifications.
