Hidden Fasteners
FASTENERS RECOMMENDED FOR USE WITH FIBERON GV DECKING include Phantom Hidden Fasteners and Phantom End Clip Hidden Fasteners. Fiberon Paramount square edge decking requires the use of Fiberon Cortex Screws, the only approved hidden face fasteners recommended for Paramount decking. Fiberon Cortex screws are available in all five colors of Paramount Decking.

Wood Grain Patterns
Note that the wood grain patterns on Fiberon decking are directional. Different looks can be achieved by laying the decking in the same or alternating directions. There are several different wood grain patterns. See Figure 10 below for one of these patterns.
The graining pattern repeats approximately every 44" feet along the board length. To ensure you orient the boards to achieve the desired effect, a directional label is noted on the side of each board showing grain direction. During the planning phase of any deck project, arrange decking before installation to achieve the desired pattern and color effect (Figure 11). This is also important if different lengths/bundles of material are used as different wood grain patterns and color tones may need to be mixed to achieve the desired look.


Do not install decking directly to a solid surface. Make sure there is adequate and unobstructed air flow under the deck to prevent excessive water absorption. Improve drainage or grade flat areas where standing water may gather. Allow a minimum of 6" between the bottom of the deck substructure/joists and the ground. The deck design must allow unrestricted airflow under at least 50% of its perimeter to permit adequate ventilation.

Fascia Installation
Fascia is intended as a non-structural covering for rim joists, risers and stringers. Screws should be installed at a maximum 12" interval, with three screws across the face at each interval (Figure 12). For Paramount, also apply a zigzag bead of high quality exterior adhesive to the entire length of the back (smooth side) of the board, within 2" f the edges and ends. Do not over-tighten screws as buckling and cracking may result. Install with 1/8" spacing between the edges and ends in temperatures above 50° F. Leave 3/16" space between edges and ends in temperatures below 50° F.

Fire and Unusual Heat Sources
Composite decking will retain heat when exposed to direct or reflective sunlight. Exercise caution if walking barefoot as footwear may be required. Fire and unusual sources of heat and heat buildup can potentially damage Fiberon decking surfaces. Examples would include fire, reflected light from different types of glass (ex. low-e glass), fire features and under-deck waterproofing installations that do not provide the 6" of un-obstructed net free ventilation.

  • Low-E Glass/Reflected Heat
    Low-emissivity glass is designed to prevent heat gain inside the house by reflecting sunlight outward. This reflective property can result in excessive heat buildup on the surface of Fiberon decking and on exterior surfaces.

    When the sunlight is reflected and concentrated it can harm a range of building materials that include doors, windows, siding, trim and decking. Damage caused to these products can include melting, sagging, warping, discoloration, increased expansion and contraction and accelerated weathering.

    If you have questions on how to reduce this risk, contact the manufacturer of the product which contains the Low-E glass for suggestions on how to reduce or eliminate the reflected heat.

  • Under-deck waterproofing systems
    Under-deck waterproofing systems, properly installed, can provide additional living or storage space. Improper installations are those that restrict air flow and result in buildup of heat and/or humidity which can result in unwanted consequences.

    Contact the manufacturer of the specific under-deck waterproofing system for installation instructions to ensure required 6" of un-obstructived net-free ventilation is achieved for Fiberon decking. If already installed, seek methods to achieve the ventilation requirement.

  • Fire Features/Fire Pits
    Fire features and fire pits are increasingly popular in outdoor living environments. Fire can damage many building products including Fiberon decking. Improperly installed fire features and fire pits can cause damage to the surface of Fiberon decking via direct exposure to the flame or excessive radiated heat.

    Proper caution should be taken when designing, installing and using these features to ensure damage does not result.

Dry or windy environments may create a temporary condition of static electricity, which will vary depending on climate and site conditions.

In the case of excessive static buildup on an installed PVC or HDPE capped deck, Fiberon recommends to use the following procedure:

  1. Remove loose debris from the deck surface.
  2. Dilute ACL Staticide® Concentrate 1 part to 39 parts water (1:39).
  3. Spray or mop entire surface of the deck.
  4. Allow to air dry - do not attempt to wipe the surface dry as wiping will reduce the effectiveness of the antistatic coating (*Although very safe in diluted form, ACL Staticide® Concentrate is considered a hazardous chemical non-diluted. DO NOT use ACL Staticide® Concentrate non-diluted.)

    Important Ladder Usage
    Safety Instructions

    When using a ladder on composite decking, it is mandatory to lay down a sheet of plywood over the deck surface to disperse the load of the ladder’s feet to nearby underlying joists. Drill fasteners downward through the top of the plywood sheet to keep it from slipping. Position fasteners so they adequately protrude and rest firmly in the gaps between the deck boards and into the joists. This will avoid leaving holes in your decking once the plywood sheet is removed. Be sure to always follow the ladder manufacturer’s instructions and safety tips.
