Product Description
Moisture Proof Hollow WPC Deck Flooring 140x23mm Co Extruded
Product Summary
- Scientific Hollow 140×23 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 140×23 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?
Yes, absolutely. While the hollow 140×23 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?
The moisture-proof shield wraps entirely around the exterior profile of the 140×23 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?
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 140×23 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?
It is the premier choice for rooftop projects. Rooftop gardens have strict maximum weight load capacities. Our hollow 140×23 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.
