TimberTech Legacy Collection stands out with its 4-sided polymer cap featuring Mold Guard technology to resist mold, mildew, and rot on all sides. Most composite decking protects three sides. Legacy protects all four. Legacy is capped on all 4 sides, providing better moisture protection than the 3-sided caps typically found on Trex Transcend.
The boards measure 0.94 inches thick by 5.36 inches wide (nominal 5/4” x 6”), with 12-foot, 16-foot, and 20-foot lengths available. The material contains approximately 85% recycled content, including post-consumer plastics like plastic bags and milk jugs. That recycled content claim actually means something when freeze-thaw cycles test every board’s integrity.
Material Specifications and Dimensions
The Legacy Collection provides a natural wood look with a craftsman hand-scraped texture and vibrant color blends that look unique from every angle. That hand-scraped texture matters. Smooth composites show every scuff mark. This texture conceals the wear that Montana’s short, intense outdoor season delivers.
| Specification | Value |
|---|---|
| Actual Thickness | 0.94 in |
| Actual Width | 5.36 in |
| Nominal Dimensions | 5/4 in x 6 in |
| Standard Lengths | 12 ft, 16 ft, 20 ft |
| Edge Profiles | Grooved (for hidden fasteners), Square-shoulder (for exposed edges and stairs) |
| Recycled Content | Approximately 85% |
The boards come in grooved profiles for hidden fasteners and square-shoulder profiles for exposed edges and stairs. Use grooved boards for the main deck to achieve a fastener-free surface. Use square-shoulder boards for perimeter, stairs, and fascia.
Installation Requirements and Fastener Systems
Installation requires 16-inch on-center joist spacing for residential applications and 12-inch on-center for commercial or diagonal installations. Don’t push those spans. Montana snow loads demand proper support.
The Legacy Collection works with multiple fastener systems:
- CONCEALoc® Hidden Fasteners (for grooved boards)
- SIDELoc® Hidden Deck Screws
- Cortex® Hidden Fastening System (for square edge boards)
- FUSIONLoc®
- TOPLoc® Face-Fastening System
The Legacy Collection is fully compatible with TimberTech railing systems including Classic Composite and Impression Rail. Accessories include matching fascia boards (12 ft), stair riser boards (12 ft), post caps, and lighting accessories.
Performance and Warranty Coverage
TimberTech backs the Legacy Collection with a 30-year limited warranty for both structure and fade/stain resistance. Features include WUI compliance and heat resistance, making it suitable for various environmental conditions.
Reviews show an overall rating of 3.4 out of 5 stars based on 5 reviews from Lowe’s. Common pros include realistic hand-scraped texture and rich color depth, while cons mention potential for scratches from pets.
The boards handle residential decks, patios, pool decks, and rooftop decks, plus high-traffic outdoor commercial spaces. TimberTech positions Legacy as a composite-core product, while Vintage and Landmark are part of the ‘Advanced PVC’ line with no wood fibers.
The 4-sided capping sets Legacy apart. Spring melt saturates deck boards from below. Most composites protect the top and sides but leave the bottom exposed. Legacy’s full encapsulation addresses Montana’s reality — moisture attacks from every angle.
