How to use
Naturale Magellan (premium, heavy brushed grain, 25-yr fade, 16″ joist OC OK), Voyager (mid, includes Swedish Red color, 16″ OC OK), Sanya (value-plus, mostly solid tones, 12″ OC required), Olympia (entry SKU, 4 solid colors, 12″ OC required). All four lines share NewTechWood's signature 4-sided cap — unique in the U.S. composite market.
21 colors total. Magellan + Voyager carry the deep tropical Brazilian Ipe + Hawaiian Charcoal palette (these run hot — heatRating 1). Sanya leads with Sand (cool beige) + Coffee + Charcoal. Olympia keeps it simple: Brown, Gray, Walnut, Slate. Heat-warning flagged automatically below 60″ deck height.
Length × width in feet. Pattern: parallel (7% waste — the 4-sided cap reduces edge-crack waste vs 3-sided competitors at 10%), picture-frame (12% waste, 1.18× labor), diagonal 45° (15% waste, 1.12× labor). Calculator quantizes board count using NewTechWood's DIY-friendly stocked 8/12/16 ft lengths.
UltraShield hidden clip is the default — 200 stainless clips/box, $95/box, ~50 sqft coverage. UltraShield color-matched torx face-screw is the alternative — 350 screws/box, $24/box, ~50 sqft coverage. Both are NewTechWood-branded and warranty-approved.
UltraShield Composite Rail ($72/lf installed — matching 4-sided cap on rails), UltraShield Aluminum ($135/lf — powder-coated, slim sightline), Generic Composite ($58/lf — White or Charcoal only). NewTechWood-branded railings carry the same 25-yr warranty as the deck boards.
UltraShield LED post-cap + riser kit + 95W transformer + low-voltage wire. Color-temperature is warm white (2700K) — matches Magellan's wood-tone palette especially well.

How we calculate
The NewTechWood UltraShield Calculator is the brand-deep estimator for NewTechWood America's UltraShield capped composite decking — the only major brand on the U.S. market with a 4-sided cap (full board enclosure). Most composites (Trex, TimberTech, Fiberon, Deckorators) cap only 3 sides — top + two edges — leaving the bottom face bare. That bare bottom is the #1 failure point for moisture ingress in humid climates, ground-contact installs, and pool-deck splash zones. NewTechWood UltraShield's 4th cap face protects the underside too. Lineup: Naturale Magellan (premium, heavy brushed wood-grain, 6 colors, $5.80/lf — price-matches Trex Transcend 15% lower), Naturale Voyager (mid, 6 colors with unique Swedish Red, $4.85/lf), Naturale Sanya (value-plus, 5 solid-ish colors, $4.10/lf, requires 12″ joist OC), and Olympia (entry SKU, 4 colors, $3.50/lf, 12″ joist OC). 100% recycled HDPE + reclaimed wood + bamboo fiber core. Real BoM with UltraShield clip count, optional UltraShield color-matched torx screws, optional UltraShield Lighting, and a 4-line auto-comparison. Pricing reflects 2026-Q1 retail at NewTechWood dealers + Amazon.
Per-LF retail prices reflect 2026-Q1 NewTechWood pricing at NewTechWood Authorized Dealer + Amazon channel. UltraShield clip + face-screw specs from NewTechWood install manual rev. 2024. 50-yr structural / 25-yr fade warranty per NewTechWood published terms. NewTechWood is not stocked at Home Depot or Lowe's — dealer-direct + Amazon channel only.
Rows = ceil(width × 12 ÷ (5.5 + 0.125)) (5.5″ board face, 1/8″ install gap). Waste % is pattern-driven; NewTechWood's 4-sided cap saves ~3pp on parallel waste vs 3-sided composites because the bottom cap protects the edges from cracking during install.
Each UltraShield box ships 200 stainless clips and covers ~50 sqft at the line's required joist OC (12″ for Sanya/Olympia, 16″ for Magellan/Voyager). Box price $95; loose clip remainder at $0.55 each.
Magellan + Voyager: joistOC = 16″ (DCA-6 perpendicular install). Sanya + Olympia: joistOC = 12″ (lighter cores have reduced effective span). Switching from Magellan to Olympia on a 16ft deck adds 4 joists (12 vs 8) — visible in the BoM.
NewTechWood Magellan at $5.80/lf vs Trex Transcend at $6.80/lf — both are premium-tier capped composite with 25-yr fade. On a 400 lf project the materials savings is $400, plus NewTechWood's 4-sided cap (Trex Transcend is still 3-sided). Trade-off: Trex has wider dealer network + brand recognition for resale.
On parallel-installed boards, NewTechWood UltraShield's 4-sided cap means cut-edge crack propagation is dramatically reduced because the bottom cap stabilizes the core. Industry-standard waste for 3-sided composites is 10% for parallel; NewTechWood publishes 7% in their installer manual. On a 1,000 sqft deck that's ~30 fewer lf of material — about $175 saved on Magellan.

People also ask
NewTechWood UltraShield is the only major capped composite brand on the U.S. market with a 4-sided cap — meaning the polymer cap fully encloses all four faces of the board (top + two edges + bottom). Trex, TimberTech AZEK, Fiberon, and Deckorators all use 3-sided caps — top + two edges only — leaving the bottom face as bare composite core. The bare bottom is the #1 failure point: humid crawl-spaces, ground-contact installs (where the deck sits within 6″ of grade), and pool-deck splash zones all push moisture into the unprotected underside. The 4th cap face on UltraShield prevents that ingress. For pool decks, ground-contact installs, and humid Southeast/Gulf Coast climates, the 4-sided cap is the deciding feature — and it's the reason NewTechWood is the most recommended composite for pool decks by independent reviewers.
Comparable on engineering, different on brand depth. Both are capped composite with co-extruded HDPE polymer caps, 25-yr fade & stain warranty, and similar density (~58-62 lb per 16ft board). Where NewTechWood wins: 4-sided cap (Trex is 3-sided), 15% cheaper per lf ($5.80 Magellan vs $6.80 Transcend), 100% recycled content (Trex publishes 95%). Where Trex wins: dealer network breadth (Trex is at Home Depot + Lowe's; NewTechWood is dealer-direct + Amazon), brand recognition for resale, broader color palette across 3 lines (12+ Trex colors vs NewTechWood's 6 Magellan colors). For DIYers buying via Amazon, NewTechWood Magellan is the value-premium pick. For brand-conscious whole-home renovations, Trex still wins resale-comp.
Sanya and Olympia use lighter cores (less polymer + more void in the extrusion profile) than Magellan and Voyager. Lighter cores have reduced effective span — meaning the board will deflect more between joists. NewTechWood's published installer manual requires 12″ joist on-center for both Sanya and Olympia (vs 16″ for Magellan and Voyager). On a 16ft deck this adds 4 extra joists (12 instead of 8) — about $90 in extra PT lumber + $40 in extra hangers. Calculator automatically adjusts the framing BoM when you switch lines.
Tier ladder: Magellan ($5.80/lf premium, heavy brushed grain emboss, 6 deep tropical-tone colors including Brazilian Ipe + Hawaiian Charcoal), Voyager ($4.85/lf mid, moderate emboss, 6 colors including the unique Swedish Red), Sanya ($4.10/lf value-plus, light emboss with mostly solid tones, 5 colors led by Sand + Coffee), Olympia ($3.50/lf entry, minimal emboss, 4 solid colors — Brown/Gray/Walnut/Slate). All four share the 4-sided cap and 50-yr structural / 25-yr fade warranty. Magellan and Voyager allow 16″ joist OC; Sanya and Olympia require 12″ OC (lighter core).
$32-62 per square foot installed depending on line + pattern + complexity. A 16×20 (320 sqft) Magellan deck with UltraShield Composite rail and 4 stairs lands around $17,000 nationally; the same deck in Olympia entry SKU with Generic Composite rail lands around $11,500. Sanya and Olympia carry a labor premium of ~$90-130 because of the 12″ joist OC requirement (more joists = more time framing). Multiply by ~0.92× South or ~1.28× West Coast. Calculator outputs project-low to project-high range.
NewTechWood's hidden-fastener system for grooved boards. Each box ships 200 stainless-steel clips and covers ~50 sqft. Box price is $95; loose clips $0.55 each. The clip nests into the grooved edge of the board and screws into the joist, leaving a fastener-free deck surface. The clip is industry-standard 200/box (Trex TUHF is 90/box; TimberTech CONCEALoc is 175/box) — UltraShield's higher clip count per box is the best value-per-box in the industry.
NewTechWood is sold through (1) NewTechWood Authorized Dealers — use the dealer locator at newtechwood.com/dealer-locator, (2) direct Amazon shipment — popular for DIYers because Amazon Prime delivery on full 16ft pallets is unmatched in the composite-deck industry, and (3) select Costco warehouse pop-up events. NewTechWood is NOT stocked at Home Depot or Lowe's — that channel is locked up by Trex (Home Depot) and TimberTech (Lowe's). For DIYers, Amazon is the fastest path (5-7 day delivery on most colors).
Yes — NewTechWood UltraShield carries a 50-year limited structural warranty on residential installs (longer than Trex's 25-yr or TimberTech's 30-yr structural). Plus 25-year fade & stain warranty on residential, 10-year warranty on commercial installs. Transferable one-time to a future homeowner at no charge. Register at newtechwood.com/warranty within 30 days of install. Note: NewTechWood warranty claims are processed in Houston (HQ) — typical claim window 3-6 weeks, slightly longer than Trex (1-3 weeks) because of NewTechWood's smaller customer-service team.
Yes — and this is where NewTechWood's 4-sided cap is genuinely best-in-class. Pool decks face moisture intrusion from both top (splash) AND bottom (humid air pooling under the deck + occasional water under the deck during pool drainage). 3-sided-cap composites are vulnerable on the underside; UltraShield's 4-sided cap protects that face. Lighter colors (Sanya Sand, Voyager Egyptian Stone Gray) are best for poolside because the heatRating 3 colors stay cool barefoot.
Yes — NewTechWood publishes 100% recycled content (HDPE from milk jugs + reclaimed wood fiber + bamboo). Trex publishes 95% recycled. TimberTech AZEK is 0% recycled (virgin PVC). For LEED projects, USGBC MR Credit 4 (Recycled Content) gives the most points to NewTechWood. NewTechWood is also the only major composite using bamboo fiber in the core — bamboo is slightly stiffer than wood fiber, which helps NewTechWood meet DCA-6 perpendicular span tables for Magellan and Voyager at 16″ joist OC.
Once you set length × width + pattern + fastener + stairs, the calculator prices the exact same deck across all 4 NewTechWood lines (Magellan, Voyager, Sanya, Olympia) using each line's per-LF retail + the correct joist OC for that line (Sanya and Olympia add framing cost from 12″ OC). Side-by-side total range + per-sqft. Tap any to switch the calc to that line; color picker resets to that line's first color and the BoM updates the joist count.
