148x21mm Decorative WPC Board Wall Cladding Interior Exterior UV Resistance

Cost Effective WPC Cladding Reduces Bulk Project Budgets

Product Summary

This traditional first-generation WPC cladding offers a high-strength, solid wood-fiber matrix that delivers a rustic timber look at a fraction of the cost of real wood. Perfect for large-scale, budget-driven commercial facades, it provides a stable exterior finish without the upfront high expense of capped composites.

Product Features

• Ultra-Competitive Sourcing Cost

• The streamlined single-extrusion process lowers factory production overhead, allowing wholesalers to maximize profit margins on competitive commercial tenders.

• 100% Solid Full-Body Sanded Finish

• With no plastic-looking outer shield, the entire board is sanded to expose real wood fibers, giving it a natural matte texture and excellent anti-glare properties.

• Easy Onsite Sanding and Repair

• Because the color and material are uniform throughout the board, any deep scratches from construction can be easily erased with standard sandpaper.

How to Install

Installing the Joists:

If the cladding panels are installed horizontally, the joists must be installed vertically (and vice versa). Fix the joists to the wall using expansion screws. Keep the center-to-center distance between the joists at 30cm - 35cm (if the spacing is too wide, the wall will sag or flex).

Fixing the First Panel:

Start from the bottom or the side. Use a starter clip (or screws) to secure the edge of the first panel to the joists. Make sure to double-check that this first piece is perfectly level or vertical.

Interlocking & Securing:

Insert the tongue (male profile) of the next panel into the groove (female profile) of the previous one. Snap the dedicated fixing clip onto the exposed joint where the panel meets the joist, and tighten the screw. Repeat this process, stacking them like building blocks.

Finishing & Trimming:

Cut the final panel to fit the remaining space. Cover and seal all perimeter edges and corners using matching L-shape corner trims

FAQ

Q1: How does first-generation WPC cladding behave with water absorption compared to capped WPC?

A1: Without a polymer shield, first-generation WPC has a standard water absorption rate of around 1% to 2%. To ensure longevity, it must be installed with proper ventilation space behind the boards to allow moisture to evaporate naturally.

Q2: Will this traditional WPC cladding change color after being exposed to the sun?

A2: Yes, this is a normal characteristic of first-generation WPC. Due to the natural wood fibers on the surface, the color will experience a slight fading (about 10% to 15%) within the first 2 to 3 months of UV exposure before reaching a completely stable, permanent shade.

Q3: Can we stain or apply a clear water-resistant sealer onto this 1st generation WPC?

A3: Yes. Unlike co-extruded boards which repel paints, the exposed wood fibers of this traditional profile can absorb professional oil-based WPC stains or sealers, allowing you to refresh the color or enhance oil-resistance after years of use.
