Wall Sandwich Panels（墙体夹芯板） are used for vertical cladding of buildings. They provide thermal insulation, aesthetic finishes, structural enclosure, and often serve as the visible façade.

Design & Construction

• Panels are attached to girts (horizontal support members) or structural frames.

• Joint systems could be open, hidden, or overlapping, with appropriate sealing to prevent air and water infiltration.

• Core thickness in wall panels is often less than roof panels (e.g. 40 mm, 60 mm, 80 mm), though for high-insulation buildings thicker panels are used.

• The facing layers may have decorative coatings or profiles (smooth, ribbed, stucco, wood-imitation, etc.).

Performance

• Thermal insulation: helps reduce heating/cooling demands.

• Sound insulation: some combinations of core/facing can reduce noise.

• Fire rating: for walls high fire rating is often required; using mineral wool cores or fire-retardant cores is common.

• Aesthetic flexibility: wide range of colors, textures, and profiles.

Applications
Used in industrial buildings, warehouses, office buildings, retail complexes, schools, and any building requiring a controlled interior environment. Wall sandwich panels often integrate with roof panels to provide a seamless envelope.
