The brand-deep estimator for NewTechWood America's UltraShield capped composite decking — the only major brand with a 4-sided cap (full board enclosure). Trex / TimberTech / Fiberon / Deckorators all leave the bottom face bare; UltraShield's 4th cap face protects the underside from humid crawl-spaces, ground-contact installs, and pool-deck splash. Lineup: Naturale Magellan (premium, $5.80/lf — 15% cheaper than Trex Transcend), Voyager (mid, includes the unique Swedish Red), Sanya (value-plus, 12″ joist OC), Olympia (entry SKU, 12″ joist OC). Real BoM with UltraShield clip count, optional color-matched torx screws, optional Lighting, and 4-line auto-comparison.
IRC R312 requires 36″ guardrail above 30″.
IRC R312 requires 36″ guardrail above 30″. 40 lf of UltraShield Composite Rail priced at $72/lf.
Naturale Magellan 4-sided capped composite. Longest residential structural warranty in the industry — beats Trex (25-yr) and TimberTech (30-yr). Register at newtechwood.com/warranty within 30 days of install.
Naturale Magellan is fully enclosed in the polymer cap (top + two edges + bottom). Trex, TimberTech, Fiberon, and Deckorators all leave the bottom bare. Best-in-class for humid crawl-spaces, ground-contact installs, and pool decks.
UltraShield hidden-fastener system — 200 stainless clips per box, 50 sqft coverage. Higher clip count per box than Trex TUHF (90/box) or TimberTech CONCEALoc (175/box). Box price $95.
Dark UltraShield colors (Brazilian Ipe, hex #5F3220) measure 140-155°F at the surface in 90°F sun. The 4-sided cap doesn't change surface temp — only moisture protection. For pool-deck installs, switch to a heatRating 3 color (Sand, Westminster Gray, Egyptian Stone Gray) for ~15°F cooler surface temps.

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.
