140*23mm Weatherproof WPC Decking Panel Co Extruded UV Resistant

Product Specification

140*23 UV resistant weatherproof Co-extruded WPC decking

Product Summary

This ultra-premium layout introduces the UV resistant, weatherproof Co-extruded WPC decking specifically engineered for luxury coastal resorts, high-end rooftop gardens, and premium residential landscapes exposed to intense solar radiation and severe climate shifts. By embedding high-concentration UV stabilizers directly into its 360-degree Co-extruded polymer shield, this advanced profile completely prevents photochemical fading and chalking. Simultaneously, the fully encapsulated, non-porous outer layer shields the composite core from continuous moisture, sub-zero freezes, and blistering heat waves. This overview directly eliminates common complaints of fading and climate-induced warping, providing a long-lasting, color-fast flooring solution.

Product Features

• Long-Term UV Resistant Color-Fastness 

• The outer armor of our Co-extruded WPC decking contains premium grade anti-UV stabilizers and light fastness color pigments. This advanced shield reflects destructive ultraviolet rays, preventing the material from oxidation, whitening, or fading, ensuring that your rich timber tones look brand new even after years in intense high-altitude sunshine. 

• Ultimate Weatherproof Engineering

• Engineered to survive the world’s harshest outdoor climates, this Co-extruded composite forms a fully sealed barrier against water, snow, frost, and high-ambient heat. The shell expands and contracts at a microscopic, controlled rate, preventing structural splitting, checking, or structural degradation across all four seasons.

• 360-Degree Total Core Shielding 

• Unlike semi-capped alternatives, our premium profile features a complete 360-degree Co-extruded protective shield that seals even the bottom and the side grooves. This total encapsulation isolates the organic core from damp undersides and ground-level humidity, ensuring absolute structural longevity without deep rot.

How to Install

1. Subframe Spacing (Max 350mm)

Install your joists (wood or aluminum) on a level, draining foundation. Joist spacing must be a maximum of 350mm center-to-center to prevent the deck from sagging.

2. Lock the First Board

Screw Starter Clips into the edge of each joist. Slide the groove of your first WPC board firmly into these clips to lock the outer perimeter without surface screws.

3. Install Center Clips

Slide Hidden Fastening Clips into the inner groove of the board at every joist intersection and screw them down. These clips automatically create the mandatory 5mm side-to-side expansion gap. Slide the next board into place and repeat.

4. Manage End-to-End Joints (Double Joists)

Where two board ends meet:

• Must use Double Joists: Each board end must rest on its own independent joist and clip.

• Leave an Expansion Gap: Leave a 5mm to 8mm end-to-end gap so the boards can expand in summer without buckling.

5. Perimeter Wall Gap & Fascia

• Wall Clearance: Always leave a 10mm gap between the decking and any brick wall or solid structure.

• Finishing: Cover exposed hollow edges by screwing on a WPC Fascia Trim around the perimeter.

FAQ

Q1: How does a Co-extruded WPC deck achieve permanent UV resistant traits compared to standard composite?

A1: Standard composite decking exposes raw wood fibers to the air, which quickly oxidize and turn ash-gray under the sun. Our Co-extruded decking locks the wood core inside a durable polymer casing enriched with high-potency UV blockers. This shield absorbs and neutralizes solar energy, maintaining consistent color retention over decades. 

Q2: Is a Co-extruded profile truly weatherproof enough to be installed right beside saltwater ocean boardwalks?

A2: Yes, absolutely. Ocean boardwalks face a combination of harsh UV rays, extreme heat, and corrosive salt mist. The weatherproof Co-extruded shield is chemically inert and completely non-porous, meaning ocean salt spray cannot corrode or pit the surface, and the internal core is perfectly protected from moisture-induced breakdown. 

Q3: Will the Co-extruded outer cap separate or peel off from the inner WPC core under extreme hot climates?

A3: No, never. The 360-degree Co-extruded casing and the inner core are fused together simultaneously during a high-heat, high-pressure extrusion process. Because they are molecularly bonded while both materials are still in a molten state, they form a single indestructible unit that cannot delaminate or peel, even in scorching deserts. 

Q4: Does the weatherproof polymer shield hold up well to sub-zero winter temperatures and freezing snow?

A4: Yes. The engineered polymer used in our Co-extruded cap is specially formulated to retain its flexibility and high impact strength even in severe sub-zero winters. It will not become brittle or fracture when frozen snow accumulates on top, allowing easy ice clearing and reliable cold-weather infrastructure performance.
