Moisture Proof Hollow WPC Deck Flooring 140x23mm Co Extruded

Moisture-proof hollow 140x23 Co-extruded WPC decking

Product Summary

• Scientific Hollow 14023 Lightweight Performance

• Engineered with the highly optimized 140mm width and 23mm thickness profile, our hollow Co-extruded WPC decking utilizes internal engineering arches to eliminate unnecessary structural weight. This lightweight design reduces dead-loads on rooftop balconies and floating frames by up to 25% compared to solid boards, significantly lowering shipping fees and speeding up on-site labor logistics. 

• 360° Shielded Moisture-Proof & Rot Resistance

• The composite core is completely encapsulated by an ultra-dense, engineering-grade polymer casing that wraps into the side grooves. This moisture-proof shield acts as an impenetrable barrier against torrential rains, standing pool water, and the continuous high humidity underneath the deck framing, guaranteeing zero deep-tissue black mold, mildew, or rot. 

• Internal Air Ventilation & Rapid Drainage Channels

• The hollow multi-chamber interior of the 14023 profile serves a double purpose. It doesn't just reduce weight; it functions as continuous internal ventilation tunnels. This allows moisture on the sub-frame to evaporate rapidly and prevents cold-weather internal condensation buildup, maintaining excellent long-term dimensional stability through all seasons.

FAQ

Q1: Is a hollow 140*23 Co-extruded profile strong enough for heavy outdoor patio furniture?

A1: Yes, absolutely. While the hollow 14023 profile is engineered to be lightweight, its internal walls are manufactured with thickened high-tensile composite ribs. When fully installed according to code with the correct joist spacing, this Co-extruded board safely distributes high downward pressures, effortlessly supporting residential dining sets, heavy planters, and family gatherings. 

Q2: How does the moisture-proof shield protect the internal hollow chambers from water damage?

A2: The moisture-proof shield wraps entirely around the exterior profile of the 14023 board, locking moisture out from ever reaching the inner wood fibers. Because the outer polymer armor is entirely non-porous and seamless, water cannot seep through the surface into the hollow chambers, ensuring the internal skeleton remains completely dry and structurally secure. 

Q3: Does the hollow 140*23 profile require special end-caps to stop bugs or water from entering the chambers?

A3: Yes, for a professional architectural finish, we highly recommend using our matching Co-extruded fascia boards or specialized color-matched WPC end-plugs. These accessories seal the open hollow 14023 chambers at the edges of your deck, preventing insects, debris, and horizontal driving rain from entering the hollow conduits. 

Q4: Can this lightweight hollow 140*23 Co-extruded board be safely installed on rooftop decks?

A4: It is the premier choice for rooftop projects. Rooftop gardens have strict maximum weight load capacities. Our hollow 14023 layout significantly cuts down on overall building stress compared to heavy solid boards or stone tiles. Combined with its premium moisture-proof shield, it delivers a high-end luxury wood appearance without compromising rooftop engineering limits.
