How to use
PRO Reserve (flagship composite, 30-yr structural, premium multi-tonal cap) is the default. Compare against PRO Legacy (mid-tier hardwood streak look) and EDGE Prime+ (value entry, Lowe's stocked). For AZEK PVC instead, use the AZEK Deck Calculator.
Four signature multi-tonal colors — Antique Leather (warm tobacco brown), Driftwood (cool weathered gray), Storm Grey (mid-tone gray), Pecan (golden brown). Each color is grain-printed on the cap for natural-looking variation rather than the uniform color of capped composites.
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 TimberTech's stocked 12/16/20 ft.
CONCEALoc hidden-clip is the default — 90 clips/box, $85/box, ~50 sqft coverage at 16″ joist on-center. Cortex (color-matched plug system, 50/pack, $38/pack) is the face-screw alternative.
Premier Aluminum ($175/lf, slimmest sightline), Reserve Composite ($90/lf, color-matched to Reserve decking — natural pair), or Builder Composite ($55/lf, value tier).
AZEK Drink Rail ($45/lf top-mount shelf) and TimberTech Lighting (post-cap + riser LED kit + 100W transformer + low-voltage wiring) are toggles.

Three honest paths. Composite wins the 25-year math for most homeowners, wood wins on upfront cost, and PVC is unbeatable around water. Each card below answers in one glance — recalculate the bill of materials by clicking a brand in the picker above.
How we calculate
The TimberTech PRO Reserve Calculator is the composite-tier deep-cut for homeowners who've decided on the PRO Reserve flagship capped composite. Reserve is TimberTech's premium composite line (one tier below AZEK PVC) — 30-yr structural + 30-yr fade & stain warranty, multi-tonal cap for natural-looking variation, and four signature colors: Antique Leather (warm tobacco), Driftwood (cool weathered gray), Storm Grey (mid-tone gray), and Pecan (golden brown). This calc covers the full TimberTech composite tier — PRO Reserve as the focus plus PRO Legacy (hardwood-streak mid-tier) and EDGE Prime+ (value entry) for side-by-side comparison. You get a real BoM with CONCEALoc clip-box count, optional AZEK Drink Rail, optional TimberTech Lighting, and a 3-line composite-tier auto-comparison. Pricing reflects 2026-Q1 retail from Lowe's Pro + TimberTech AZEK Pro dealer channel.
Per-LF retail prices reflect 2026-Q1 TimberTech composite pricing at Lowe's Pro + TimberTech AZEK Pro dealer channel. CONCEALoc + Cortex specs from TimberTech install manuals. 30-yr structural + 30-yr fade & stain warranty per TimberTech PRO Reserve published terms.
Rows = ceil(width × 12 ÷ (5.5 + 0.125)) — TimberTech composite face is 5.5″ with 1/8″ install gap. Waste % is pattern-driven.
Each CONCEALoc box ships 90 clips and covers ~50 sqft at 16″ joist on-center. Total clips = boards × (length × 12 ÷ 16 + 1).
Composite installs are 25% slower than face-screwed PT (clip-system sequencing). Pattern + shape multipliers compound.
Within the TimberTech composite tier, Reserve is the premium ($5.50/lf), Legacy is the hardwood-streak mid ($4.80/lf), EDGE Prime+ is the value entry ($4.10/lf). All carry the 30-yr structural warranty except EDGE Prime+ (25-yr).
If you're choosing between Reserve composite and AZEK Vintage PVC, run both — AZEK is $7.20/lf vs Reserve $5.50/lf. Over 25 years, the PVC premium ($1.70/lf × ~400 lf = $680) is offset by AZEK's longer warranty (50-yr vs 30-yr) and lower maintenance cost.
