Composition

This hollow core PVC wall panel is manufactured from rigid PVC compound with a square hole pattern throughout the profile. The 9 mm thickness provides structural integrity while maintaining a lightweight design. Each panel measures 40 cm in width with square apertures spaced at regular intervals. The hollow core construction reduces material weight without compromising impact resistance. Suitable for interior decoration projects where moisture resistance and ease of installation are specified.

Key Advantages

Hollow core structure reduces weight by approximately 35 percent compared to solid PVC panels of equivalent thickness.
Square hole pattern enables screw or nail fixation without pre-drilling, reducing installation time.
Closed-cell PVC formulation with water absorption below 0.1 percent prevents moisture-related degradation.
40 cm width provides balanced coverage for interior wall applications while maintaining manageable handling weight.
Resistant to mold, mildew, and fungal growth in high-humidity interior environments.

Product Characteristics

Edge profile: Tongue-and-groove joint on longitudinal edges for seamless surface assembly.
Weight per square meter: Approximately 0.9 kg, suitable for single-person handling during installation.
Square hole spacing: 150 mm center to center, aligning with standard wall stud spacing.
Surface finish: Smooth matte texture ready for painting or decorative film application.
Dimensional stability: Linear expansion coefficient of 0.065 mm per meter per degree Celsius.

Frequently Asked Questions

What fasteners work with the square hole pattern?

Use number 6 or number 8 self-tapping screws with length 20 to 30 mm, or galvanized spiral nails. Fastener head diameter should not exceed 7 mm to fit square hole opening. Maintain 1 mm gap between fastener head and panel surface for thermal expansion.

How to clean the PVC panel surface?

Use non-abrasive sponge with mild soap and water. Avoid solvent-based cleaners, bleach, or abrasive powders which may degrade the surface layer. For stubborn stains, isopropyl alcohol can be used sparingly.

What is the recommended installation temperature range?

Install panels when ambient temperature is between 10 and 35 degrees Celsius. Avoid installation below 5 degrees Celsius as PVC becomes less flexible and may crack during cutting or fastening.

Are expansion gaps required for hollow core panels?

Yes, leave 3 to 5 mm expansion gap at all wall corners, ceiling junctions, and fixed obstacles. Cover gaps with matching PVC trim profiles. This accommodates linear thermal expansion of approximately 0.065 mm per meter per degree Celsius.

Installation Guidelines

Square hole fastening: Align fasteners with square hole centers. Do not overdrive. Cutting: Use fine-tooth saw blade (10-12 TPI) or PVC scoring knife. Deburr cut edges. Acclimation: Store panels horizontally for 24 hours at 18-28°C before installation. Substrate: Must be flat within 2 mm per meter, dry, and clean.
