Fiberon Sanctuary Composite Deck Board vs Trex Select Deck Boards

Both are capped composite boards that never need painting, staining or sealing, so the choice comes down to finish and edge options. Fiberon Sanctuary gives you a multi-tonal espresso look, a 3-sided PermaTech cap and grooved edges for hidden fasteners, plus a fire-rated version. Trex Select is the simpler, more conservative pick: a solid wood-grain profile, a 95% recycled core and a choice of grooved or square edge. Pick Fiberon for a darker, hardwood-style deck with a fastener-free surface; pick Trex Select for a lighter, classic look and the flexibility of square-edge installation.

  • Choose the Fiberon Sanctuary if you want a dark, multi-tonal board with grooved edges for a clean, hidden-fastener deck and a fire-rated option.
  • Choose the Trex Select if you want a proven wood-grain board available in either grooved or square edge and a straightforward, classic color palette.

What reviewers say

Fiberon Sanctuary Composite Deck Board

Owners of Fiberon's capped composite lines generally report the boards hold their color and clean up easily, and that the grooved edge gives a clean screw-free surface. Common complaints center on dark colors getting hot in sun and on hidden clips adding cost and install time.

What people mention
  • Color retentionPraisedOwners say the capped surface keeps its Espresso tone without annual staining.
  • MaintenancePraisedNo sanding, sealing or painting is needed beyond occasional cleaning.
  • HeatCriticisedDark composite boards get noticeably hot in direct sun, which matters for bare feet and pets.
  • FasteningMixedHidden clips give a clean look but are bought separately and slow the install.

Trex Select Deck Boards

Owners of capped Trex boards generally report that the surface holds its color and wipes clean, and that the boards stay flat and splinter-free years in. Complaints center on heat underfoot, a plasticky look up close and visible fasteners on square-edge installs.

What people mention
  • Fade resistancePraisedOwners say the capped surface keeps its color through sun and seasons.
  • MaintenancePraisedSoap and water is all it takes; no staining or sealing.
  • HeatCriticisedBare feet complain the surface gets hot in direct sun.
  • AppearanceMixedThe grain reads as wood from a distance but plasticky up close.

Questions and answers

Which is better for a deck around a pool?
Both resist splintering and need no sealing, so either works. Fiberon Sanctuary's grooved edge gives a smoother, fastener-free surface underfoot, while Trex Select's lighter colors stay cooler in direct sun.
Which board lasts longer?
Both are capped composites built to resist rot, warping and fading, and both carry manufacturer warranties. Trex has the longer track record in the category; Fiberon's 3-sided cap covers the walking surface and edges.
Is Fiberon Sanctuary worth stepping up to over Trex Select?
Step up if you want the darker, multi-tonal hardwood look, a fully hidden fastener system or a fire-rated board. Otherwise Trex Select covers the basics with more edge flexibility.
Can I use hidden fasteners with both?
Yes. Fiberon Sanctuary is grooved and made for Phantom GT hidden fasteners. Trex Select comes in a grooved version for hidden fasteners, or square edge if you prefer visible screws.
Which handles pets and bare feet better?
Both are splinter-free and comfortable barefoot. Fiberon's darker Espresso surface gets hotter in full sun, so Trex Select in a lighter color may suit pets and kids better on exposed decks.
Do either need sealing?
No. Both are prefinished capped composites that never need painting, staining or sealing; soap and water cleaning is enough.
