Trex Universal Hidden Fastener — 90 clips per box, 50 sqft coverage at 16″ joist o.c. Required reading: trex.com/install. The clip nests into the board's edge groove and screws into the joist for a clean screw-free surface.
Dark Trex colors (Tiki Torch, hex #7B3F1F) measure 160–175°F at the surface in direct sun on a 90°F day. Consider switching to a Lineage color (Rainier, Carmel, Biscayne, Jasper) — Trex's heat-mitigation cap runs 20–30°F cooler at the same color depth.

How to use
Trex Signature (2024 flagship, $6.40/lf, 35-yr warranty) is the default. Compare on your exact deck against Transcend (prior flagship, $5.40/lf, 25-yr warranty) or Select (mid-tier, $4.50/lf, 25-yr warranty). The 3-line auto-compare shows the Signature premium for every choice.
Six premium colors — Whidbey (cool weathered), Aspen (light, coolest underfoot), Helios (warm sun-bleached), Maverick (mid-brown streaked), Iron Bluff (deep gray w/ grain), Carbonized (heat-mitigation cap, darkest). All carry the same 35-yr warranty.
Length × width in feet. Pattern: parallel (7% waste, 1.0× labor), picture-frame (12%, 1.18×), diagonal 45° (15%, 1.12×). Calculator quantizes board count using Trex's stocked 12/16/20 ft.
TUHF (Trex Universal Hidden Fastener) is the default — 90 clips/box, $89/box, ~50 sqft coverage. Cortex (color-matched plug, 50/pack, $38/pack) is the face-screw alternative.
Trex Signature Aluminum ($188/lf installed — slimmest sightline, the natural pair for Signature decking), Trex Transcend Composite ($95/lf), or Trex Select Composite ($78/lf).
Trex RainEscape under-deck drainage ($4.50/sqft) and Trex DeckLighting (post-cap + riser LED kit + 100W transformer + low-voltage wiring) are toggles.

How we calculate
The Trex Signature Calculator is the brand-deep estimator for Trex Signature — Trex's 2024 flagship decking line that sits above Transcend at the top of the lineup. Signature carries Trex's longest warranty (35-yr structural + 35-yr fade & stain), the most realistic hardwood-grain multi-tonal cap Trex has shipped, and a six-color palette focused on premium aesthetic: Whidbey (cool weathered driftwood), Aspen (light premium oak), Helios (sun-bleached warm), Maverick (rich mid-brown w/ streaking), Iron Bluff (deep gray w/ hardwood grain), and Carbonized (darkest, heat-mitigation cap). This calc focuses on Signature with Transcend and Select as comparison anchors so you can see exactly what the Signature premium costs on your specific deck. TUHF + Cortex fasteners, Signature aluminum railing, optional RainEscape and DeckLighting. 2026-Q1 retail.
Per-LF retail prices reflect 2026-Q1 Trex Signature pricing at Home Depot + TrexPro Platinum channel. TUHF + Cortex specs from Trex install manuals. 35-yr structural + 35-yr fade & stain warranty per Trex Signature published terms (2024 launch). Color palette + heat ratings from Trex 2024 color guide.
Rows = ceil(width × 12 ÷ (5.5 + 0.125)) — Trex face is 5.5″ with 1/8″ install gap. Waste % is pattern-driven.
Each TUHF box ships 90 clips and covers ~50 sqft at 16″ joist on-center. Total clips = boards × (length × 12 ÷ 16 + 1).
Signature is $6.40/lf vs Transcend $5.40/lf — a $1.00/lf premium. On a 400 lf project that's $400 more in materials. The premium buys 10 more years of warranty (35 vs 25) plus a more realistic hardwood cap.
Signature installs are 25% slower than face-screwed PT (TUHF clip-system sequencing). Pattern + shape multipliers compound.
Over the warranty life, Signature's higher upfront cost amortizes across 35 years vs Transcend's 25. Annual amortized cost is often LOWER for Signature when you factor the 10-year-longer warranty life.

Trex Signature is Trex's new (2024) top-of-line decking — it sits ABOVE Transcend in the lineup. Three concrete differences: (1) Signature carries a 35-yr structural + 35-yr fade & stain warranty vs Transcend's 25-yr; (2) the cap is the most realistic hardwood-grain Trex has made, with deeper multi-tonal variation; (3) Signature is $6.40/lf vs Transcend $5.40/lf — a $1.00/lf premium. For homeowners who can afford the upgrade, Signature offers measurably better aesthetic + longer warranty for ~18% more in materials.
Two reasons. First, the premium PVC market (AZEK Vintage at $7.20/lf, Zuri Premium at $7.80/lf) was eating Trex's high-end share — Signature was Trex's premium-tier response. Second, Lineage (Transcend's heat-mitigation sub-collection, launched 2024) proved homeowners would pay 9% more for cap-technology upgrades; Signature extends that premium-cap philosophy across a full new line at the top of the lineup.
$62-95 per square foot installed depending on pattern + complexity. A 16×20 (320 sqft) Signature deck with Trex Signature Aluminum railing and 4 stairs lands around $28,500 nationally; with RainEscape under-deck drainage and DeckLighting, $36,000+. Multiply by ~0.92× South or ~1.28× West Coast. Calculator outputs a project-low to project-high range.
Yes — Trex Signature carries a 35-year limited residential structural warranty AND a 35-year limited residential fade & stain warranty. That's 10 years longer than Transcend / Select / Enhance. Transferable to a future homeowner one-time at no charge. Register at trex.com/warranty within 30 days of install. Note: even at 35 years, AZEK Vintage (50-yr) and MoistureShield Meridian (lifetime) have longer warranties — pick based on which warranty length matters most for your timeline.
Aspen (heat rating 3) is the coolest — light premium-oak tone that reflects most solar heat. Whidbey is close behind (cool weathered driftwood, heat rating 3). The mid-tones (Helios, Maverick) are rating 2 — comfortable underfoot in moderate climates. Carbonized (heat rating 1, near-black) is the warmest but uses Signature's heat-mitigation cap, so it runs ~20°F cooler than Transcend Lava Rock at the same temperature. For barefoot decks in hot climates, Aspen or Whidbey are the safest picks.
Signature uses the same TUHF (Trex Universal Hidden Fastener) system as the rest of the Trex composite lineup — 90 clips/box, $89/box, ~50 sqft coverage at 16″ joist on-center. Signature boards are grooved (compatible with TUHF) by default. Cortex color-matched face-screw plug is also available for exposed-screw aesthetics.
Depends on your time horizon. The $1.00/lf premium on a 400 lf project is $400 extra in materials — modest. The 10-year-longer warranty is the real value: if you plan to stay in the home 20+ years, Signature's 35-yr warranty pays for itself in avoided early replacement. The aesthetic upgrade (more realistic hardwood cap) is subjective but consistent: most homeowners who see both side-by-side prefer Signature. If your horizon is 10-15 years, Transcend is fine.
TrexPro Platinum dealers carry the full Signature palette in stock. Home Depot stocks core Signature colors with 1-2 week special order for the full palette. Lowe's stocks less Signature than Home Depot (Trex's primary retail partner is Home Depot, AZEK Building Products' is Lowe's). Trex.com/find-a-pro maintains the dealer locator.
Yes — Signature carries the same pool-deck approval as the rest of the Trex composite lineup. The boards aren't permanently submerged-rated (for that, use MoistureShield Meridian, the only composite ICC-ES rated for water immersion), but they're approved for splash zones and adjacent-to-pool installation. Signature handles chlorinated water exposure with no issues.
Once you set length × width + pattern + fastener + stairs, the calculator prices the exact same deck across all 3 lines (Signature, Transcend, Select) using each line's per-LF retail. The side-by-side table shows total range + per-sqft for each. Tap any to switch the calc to that line; the color picker resets to that line's first color. Fastest way to see the Signature premium on your specific deck dimensions.
