TREX FASCIA INSTALLATION RECOMMENDATIONS
General Notes: » Trex Fascia utilized around the perimeter of a deck must be gapped with the same requirements as Trex decking to allow for expansion/contraction of the fascia. » When using 2" x 8" framing, attach fascia using 2 fascia recommended fasteners; when using 2" x 10" or larger framing, attach fascia using 3 fascia recommended fasteners. Top screw should be placed 1" from the top of the rim joist, the second screw in the center of the rim joist, and the third screw 1" from the bottom of the rim joist. » Refer to page 34-35 for fascia recommended fascia fasteners. WHEN USING RECOMMENDED FASCIA FASTENERS: » Recommended fascia fasteners can only be used with 1x8 or 1x12 fascia product and cannot be used with decking products that are being used as fascia trim or stair risers.
Method 1: Fascia Under Decking ( Note: reflects 2x8 fascia installation & square-edge decking).
Method 2: Fascia Beside Decking ( Note: spacers below reflect 2x8 fascia installation)
When using this method, attachment of spacers to framing may vary depending on the fascia size. If installing 1x12 fascia use two screws spaced properly apart so as to not interfere when installing fascia screws.

Install fascia UNDER decking edges/ends. This will optimize the aesthetics and performance of the installation.
Install 3/16" to 1/4" thick x minimum 1" wide exterior grade spacers (these should be cut the same length as the rim joist), and spaced 9" on center. Install fascia screws as stated below at spacer locations (ensure that spacer screw does not interfere with fascia screw).
All images shown here reflect fascia under the decking as well as using recommended fascia screws .

TIP: Prior to installing spacers, paint ends black so as these are not as visible (especially when using contrasting colors).
