Trex 12″ x 12' Select Saddle Fascia Board

This 12-foot fascia board provides a finished edge for composite decking systems, with nominal dimensions of 1 in. x 12 in. x 12 ft. The actual dimensions tell the real story — thickness varies from 0.56 to 0.75 inches, and width ranges from 11.25 to 11.375 inches. That variance matters when calculating material needs and ensuring compatibility with existing deck systems.

At 48.68 pounds per board, it’s heavy enough to stay put during Montana winds but manageable for a two-person crew. The capped composite construction uses 95% recycled materials — plastic film and reclaimed sawdust, delivering both performance and environmental benefits that matter to today’s builders.

Performance That Justifies the Premium

The warranty coverage speaks volumes: 35-year limited residential warranty, 35-year fade and stain warranty, and 25-year commercial warranty. Those aren’t marketing numbers — they’re performance promises backed by the protective shell technology.

That high-performance shell resists fading, staining, rot, and mold — crucial resistance in Montana’s extreme UV exposure and temperature swings. The mold and mildew resistance performance proves especially valuable during spring snowmelt when moisture lingers around deck perimeters.

The smooth, splinter-free finish eliminates the maintenance headaches of traditional wood fascia. No annual staining. No rot replacement after five years. Just soap and water cleaning when needed.

Installation Requirements and Compatibility

Fastener spacing requirements run 8 to 12 inches on center, with specific hardware compatibility that matters for long-term performance. The Deckfast Composite and PVC Fascia Fastening System, TrapEase 3, and TrapEase Fascia all work with this board — not every fastener will.

Pre-drilling pilot holes isn’t optional. Skip this step and risk splitting the material, especially in cold weather when composite becomes brittle. Install fascia flush to deck edge and use a fine-tooth saw for clean cuts — standard practices that prevent callbacks.

The system compatibility extends beyond fasteners: designed to match Trex Select decking, compatible with Trex railing and lighting, and works with Trex Hideaway Hidden Fasteners. That ecosystem approach simplifies material ordering and ensures color matching across the entire deck system.

FAQ

What’s the actual thickness variance on this fascia board? The thickness ranges from 0.56 to 0.75 inches — almost a quarter-inch difference. Factor this variance into your installation planning, especially when matching with existing trim or creating tight joints.

Does the 35-year warranty cover everything? The residential warranty covers defects for 35 years, with specific 35-year coverage for fade and stain resistance. Commercial installations drop to 25 years. Read the fine print — warranties require proper installation and typically exclude labor costs.

What fasteners work with this fascia? Three specific systems are recommended: Deckfast Composite and PVC Fascia Fastening System, TrapEase 3, and TrapEase Fascia. Space them 8 to 12 inches on center for proper hold.

How does this handle Montana’s temperature extremes? The capped composite shell resists the fading from high-altitude UV and the mold risk from spring moisture. Pre-drilling pilot holes becomes even more critical in cold weather when the material gets brittle.

What comes in the package? One 12-foot fascia board. Fascia screws and sub-framing support are required but not included — budget for these additional materials.
