A striking exotic wood décor

SYMMETRY composite deck boards have reached an unrivalled finishing level with their ultra-realistic imitation of exotic wood. Surface pores, as well as the wood grain, are reproduced randomly and provide an inimitable texture.

Colours are also very well imitated with an entire series of tones, ranging from red exotic wood like Cinnabar, similar to mahogany, to Iroko wood such as Warm Sienna. Warm tones ranging from ochre to copper, with more or less dark gradation, give rhythm to the deck and contribute to its vibrant character.

A SYMMETRY composite board deck thus gives off a feeling of comfort related to its perfect imitation of wood, while keeping its advantages of low maintenance, but especially the conservation of its intense colours over time.

Extrusion type

Co-extruded protection layer

A fine layer of polyethylene, covering the SYMMETRY board surface, efficiently protects the composite wood against water and any moisture pick-up. Expansions recorded are very low, with only 1 mm per linear meterwhen 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 25 years, SYMMETRY 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.

Washing tougher stains may be done with mild solvents, such as white spirit, without risk of fading.

Fiberdeck guarantees that for a 25-year period under normal and correct service conditions, and under installation conditions in compliance with instructions written by Fiberdeck, SYMMETRY 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 SANCTUARY deck boardsto stains and fadingsubject to compliance with instructions for installation and use in residential applications.

SYMMETRY 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 SYMMETRY deck boards with Cobra® 24 clips

Fiberon SYMMETRY boards must be implemented in compliance with the installation notice using Cobra 24 stainless steel clips. A bag of 90 clips fastens about 5 m2of boards.

These stainless steel 304 clips efficiently maintain boards on joists using underside grip sets. Boards are maintained without any risk of displacement over time due to impacts or expansion. Stainless steel screws are self-drilling in softwoods and exotic woods. It is necessary to use a set of "special metal" screws and aluminium joists.

SYMMETRY boards fastened using Cobra 24 clips can be removed easily without disassembling the entire deck. It is very practical to change a board or to get access under the deck, if necessary.

Joist spacing (centre-to-centre distance) must be at most 40 cm for SYMMETRY boards.

95% recycled raw materials

SYMMETRY 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 SYMMETRY composite deck boards does not harm tropical forests; it is an interesting alternative to exotic woods.

SYMMETRY screw-in finishing boards

Full profile boards identical to SYMMETRY grooved boards, but without grooves on the sides, 20 x 127 mm, 2440 mm in length and available in the same 3 colours: Cinnabar / Burnt Umber / Warm Sienna / Graphite, help create finishing strips around the deck, but also swimming pool sundecks, stairs and floor openings.

Cobra® WPC 304-grade stainless steel screws, 5 x 50 mm, offered in the same colour as the boards for greater discretion, are used to fasten these finishing boards.

Finally, it is always possible to use an aluminium angle bar to ensure the peripheral contour of the deck and mask the junction between two grooved boards.
