PU Foam Core Sandwich Panel
Qingdao Yunda PU foam core sandwich panels combine coated steel facings with a rigid PUR or PIR insulation core to provide efficient thermal insulation, lightweight construction and reliable structural performance. With a thermal conductivity as low as 0.022 W/(m·K), the panels help reduce heat transfer and maintain stable indoor temperatures in energy-efficient buildings.

Description
Qingdao Yunda
PU Foam Core Sandwich Panels deliver reliable thermal insulation and structural performance for industrial buildings, cold storage facilities, and prefabricated structures. The polyurethane (PU) foam core provides a thermal conductivity of λ = 0.024 W/(m·K), combining low weight with excellent insulation efficiency.
Available in standard thicknesses of 50 / 75 / 100 / 150 / 200 mm, each panel features a 0.5 mm PPGL steel facing on both surfaces, with optional stainless steel 304 inner facing for food-grade or cleanroom applications.
All Tseason PU foam core panels are manufactured under CE certification and ISO 9001 quality management standards, ensuring consistent performance for export projects worldwide.
