How to use
Meridian (flagship, lifetime structural + 50-yr fade, CoolDeck dark colors), Vision (premium, 50-yr structural + 30-yr fade), Vantage (mid-tier, 30-yr / 30-yr), Elevate (value, 25-yr / 25-yr). All four lines are wholly-encapsulated — that's MoistureShield's whole-product story.
Up to 6 colors per line. Meridian + Vision dark tones include CoolDeck heat-reduction (20-30°F cooler than uncapped composite at the same shade). Heat rating icons show the surface-temperature expectation in 90°F sun.
Length × width in feet. Pattern matters: parallel (7% waste, 1.0× labor), picture-frame (12%, 1.18×), diagonal (15%, 1.12×). Calculator quantizes board count using MoistureShield's stocked 12/16/20 ft.
CoolClip hidden-clip is the default — 180 clips per $132 box, covers ~90 sqft at 16″ OC. Pro Plug (50 plugs per $34 pack) is the face-screw alternative using Starborn coated screws with color-matched plug.
Pinnacle (aluminum, $158/lf installed), Cordial (composite, $92/lf), Essential (value composite, $56/lf), or no railing.
Post-cap + riser LED kit with 100W transformer + low-voltage wiring. Pair with Pinnacle aluminum railing for the cleanest sightline.

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 MoistureShield Deck Calculator is the brand-deep estimator for MoistureShield's wholly-encapsulated composite decking (Oldcastle APG). The distinctive engineering story: MoistureShield is the ONLY composite where the polymer cap encloses every face of the board — top + bottom + sides + ends — instead of just the walking surface. That gives it the only composite rating for water immersion and ground contact, plus a lifetime structural / 50-yr fade & stain warranty on the flagship Meridian line (the industry's longest composite warranty). Four lines are covered: Meridian (flagship), Vision (premium), Vantage (mid), Elevate (value). Pricing reflects 2026-Q1 retail at Home Depot + MoistureShield authorized dealers. The calculator returns a real BoM with CoolClip hidden-fastener box count, optional Pro Plug face-screw alternative, optional MoistureShield Lighting, plus a 4-line side-by-side comparison.
Per-LF retail prices reflect 2026-Q1 MoistureShield pricing at Lowe's Pro + MoistureShield Authorized Dealer channel. CoolClip + Pro Plug specs from MoistureShield install manuals. Lifetime structural warranty + 50-yr fade & stain per MoistureShield Meridian warranty terms. Water-immersion rating per ICC-ES evaluation report.
Rows = ceil(width × 12 ÷ (5.5 + 0.125)) — MoistureShield board face is 5.5″ with 1/8″ install gap. Waste % is pattern-driven.
Each CoolClip box ships 180 clips and covers ~90 sqft at 16″ joist on-center. Total clips = boards × (length × 12 ÷ 16 + 1). Loose remainder priced at $1.35 each.
Each Pro Plug pack ships 50 color-matched plugs and covers ~50 sqft. Used when fastener mode = Pro Plug (face-screw with hidden plug aesthetic).
Composite installs are 25% slower than face-screwed PT (clip-system sequencing + thermal-gap discipline). Pattern + shape multipliers compound. Region multiplier from RSMeans 2026-Q1.
Railing posts go every 6 ft. One post-cap LED per post; one riser light per stair tread; one 100W transformer per project.
