Exceptional resistance to slipping

Exceptional resistance R.12 to slipping!

Fiberon20 XTREME Advantage boards are perfectly adapted to new slip resistance requirements. They meet the strictest standards, both barefoot and with shoes, thanks to a new anti-slip coating. They are perfectly suited for pool sides and public spaces.

A useful surface and removable board

XTREME Advantage boards have grooves on their sides to enable fastening with Cobra 20 stainless steel clips. They are also available with square edges (no grooves) to create finishing skirting boards, stairs and sundecks for swimming pools.

Fastening with Cobra®20 clips make it possible to remove a board without having to disassemble the entire deck.

Co-extruded protection layer

A fine layer of polyethylene, covering the XTREME ADVANTAGE board surface, efficiently protects the composite wood against water and any moisture pick-up. Expansions recorded are very low, with only 0.9 mm per linear meter when exposed to a 30° temperature variation.

The board is completely rain-proof. Good run-off prevents water from penetrating the protected composite wood. Powerful UV-resistant additives are also added to the formula of this fine protective layer to avoid any fading over time.

The application of this over-layer is conducted at the same time as the extrusion to obtain a fusion of materials and perfect adherence over time.

No fading and no stains

In addition to their UV resistance and the absence of any fading guaranteed for 20 years, XTREME Advantage co-extruded boards require very little maintenance. Stains such as grease, wine or ketchup can be cleaned easily using soapy water.

It is, however, recommended to wash your deck using a pressure washer (120 bar maximum) at least once a year to remove any moss and lichen, which tend to accumulate in the winter and more specifically in parts not exposed to the sun.

Fiberdeck guarantees that for a 20-year period under normal and correct service conditions, and under installation conditions in compliance with instructions written by Fiberdeck, XTREME ADVANTAGE boards will not be subject to any defect related to their manufacturing, cracks, splinters, delamination, rotting or structural damage caused by fungi, wood-eating insect or termite attacks.

Fiberdeck guarantees the resistance of XTREME ADVANTAGE deck boardsto stains and fading, subject to compliance with instructions for installation and use in residential applications.

XTREME ADVANTAGE deck boards are fully resistant to stains, and their radiance is sustained by a co-extrusion process, which covers the board with a pure polyethylene film to ensure perfect sealing of the coating. Maintenance is easier and is limited to simple water rinsing.

Installation of XTREME Advantage boards with Cobra®20 clips

Fiberon XTREME Advantage boards must be implemented in compliance with the installation notice using Cobra® 20 stainless steel clips. A bag of 90 clips is required to fasten about 3.5 m2 of boards. Board gaps (centre-to-centre distances) should be at most 30 cm.

Stainless steel screws delivered in clip bags are self-drilling in softwood. It is preferable to drill a guide hole for exotic woods. When installed on aluminium joists, stainless steel "metal" self-drilling screws must be used.

Cobra 20 clips with their underside grip sets ensure excellent maintenance of boards on joists. These clips may easily be removed in order to remove a board and change it, without disassembling the entire deck

95% recycled raw materials

XTREME ADVANTAGE composite deck boards are eco-friendly products. 95% manufactured with raw materials from the recycling industry, the boards are also entirely recyclable.

High-density polyethylene (HDPE) comes from the recycling of plastic waste (plastic bottles), and the wood fibres come from sawdust from manufacturers such as furniture makers.

The manufacture of XTREME ADVANTAGE composite deck boards does not harm tropical forests; it is an interesting alternative to exotic woods.

Screw-in finishing boards

Full profile boards identical to SYMMETRY grooved boards, but square-edged (no grooves), 20 x 127 mm , 2,440mm in length and available in the same 3 colours: Aspen grey / Acorn Brown / Beige Brown, help create finishing strips around the deck, but also sundecks around a swimming pool, stairs and floor openings.

Stainless steel 304 Cobra® WPC screws, 5 x 50 mm, offered in the same colour as the boards for more discretion, fasten these finishing boards.
