TimberTech’s Terrain Collection delivers 4-sided polymer capping with Mold Guard® technology: the kind of complete moisture protection that actually matters when your deck faces Montana’s freeze-thaw cycles. At ~85% recycled content from plastic bags and milk jugs blended with reclaimed wood fibers, this capped composite hits the sweet spot between green building requirements and measurable performance.
The 30-year limited warranty backs up what contractors see in the field: 4-sided capping significantly outperforms uncapped composite for moisture and mold resistance.
Core Specifications That Matter
Actual board dimensions run 5.36 inches wide by 0.94 inches thick. Available lengths include 12-foot, 16-foot, and 20-foot boards. That 20-footer saves splice joints on bigger mountain decks.
| Component | Dimensions | Application |
|---|
| Deck Boards | 5.36” × 0.94” | 12’, 16’, 20’ lengths |
| Fascia | 0.58” × 11.95” × 12’ | Deck perimeter finishing |
| Riser | 0.58” × 7.25” × 12’ | Stair facing |
Three profile options handle different installation preferences: Square-shoulder (Square Edge), Grooved, and Scalloped (Terrain+ variation). Grooved boards work with hidden fastener systems while square-edge boards take standard top-down fastening.
The 4-sided capping ensures moisture protection even within the grooves: a detail that matters when spring snowmelt keeps boards damp for weeks. Traditional wood won’t match this performance: no warping, splitting, or splintering, plus it retains color without annual staining or sealing.
Installation Reality for Montana Contractors
CORTEX hidden-fastener compatibility with material-matched plugs streamlines installation for contractors who’ve already invested in that system. Standard deck framing with 16-inch on-center joist spacing handles residential loads: no special framing requirements that complicate bids.
The dual fastening approach (grooved boards for hidden systems, square-edge for face-screwing) means contractors can match installation method to customer preference without switching product lines. Matching Terrain Collection fascia and riser boards come in all collection colors, eliminating the color-matching headaches that plague mixed-material installations.
Customers rate it 4.7 out of 5 stars, highlighting the authentic wood look and durability. That’s actual homeowner feedback, not marketing copy.
FAQs
What makes the 4-sided capping worth the premium over 3-sided products?
The 4-sided polymer capping provides moisture protection even within the grooves, preventing the water intrusion that causes board failure in freeze-thaw climates. Compared to uncapped composite, it delivers significantly higher resistance to moisture and mold.
How does the recycled content affect performance?
The ~85% recycled content comes from plastic bags and milk jugs blended with reclaimed wood fibers. This engineered blend provides consistent performance while meeting green building requirements: the recycled polymers actually improve moisture resistance compared to virgin materials.
What warranty coverage should contractors communicate to clients?
The 30-year product limited warranty includes a 30-year fade and stain limited warranty. Limited labor replacement warranty applies when installed by an authorized TimberTech contractor.
