Which is cheaper per foot of deck?

The Fiberon is far cheaper per board: $24.61 for 20 ft at Warehouse '71 versus $74.50 for 16 ft at Home Central, both as of November 5, 2026. That works out to about $1.23 per linear foot for the Fiberon and about $4.66 for the Trex.

Trex backs the Select with a 25-year limited residential warranty, and its full outer shell protects all four sides. The Fiberon listing states no warranty term, and its PermaTech cap covers three sides.

Is the Trex Select worth the extra money?

Only if the warranty and the solid gray look matter more to you than price. The Fiberon does the same low-maintenance job for roughly a quarter of the cost per foot.

Can I use hidden fasteners with both?

Yes. Both boards have grooved edges for hidden clip fasteners, and the Fiberon listing names Fiberon Phantom GT fasteners. Fasteners are not included with either board.

Which is better for a large deck?

The Fiberon, because 20 ft boards mean fewer butt joints and less waste on long runs. The Trex Select tops out at 16 ft, so expect more seams.

Do either need painting or sealing?

No. Both are capped composites that clean with soap and water and need no sanding, staining, or sealing.
