What defines the Terrain+ Collection?

Frequently Asked Questions

What are the best fasteners to use with the Terrain+ Collection®?

The best fastener depends on your board profile and the finished look you want. Terrain+ comes in both grooved and square-shouldered profiles, and it works with several TimberTech fastener systems:

CONCEALoc®for grooved boards when you want a hidden-fastener finish

CORTEX® for a top-down install with color-matched plugs made from the same boards

TOPLoc® for Composite for color-matched, top-down face fastening

Here's a helpful distinction: Unlike the standard Terrain Collection®, CORTEX® is compatible with Terrain+. Color-matched CORTEX® plugs and screws are available in Natural White Oak, Weathered Oak, and Dark Oak, including options for Terrain+ fascia boards, for a near-seamless surface.

What is the maximum joist spacing for the Terrain+ Collection®?

For the Terrain+ Collection®, follow the joist spacing outlined in the current TimberTech installation guide for your specific profile and application. Proper spacing keeps your deck flat, secure, and warranty-eligible, so it's worth confirming the exact requirement before you build.

Standard Terrain+ boards: Confirm on-center spacing in the installation guide.

Stairs, diagonal layouts, and commercial applications typically require tighter spacing.

What colors are widely available? Are there local exclusions?

The Terrain+ Collection® offers three signature colors, each with a subtle wood grain and sophisticated, cascading color:

Natural White Oak

Weathered Oak

Dark Oak

All three are part of the core Terrain+ line, available in standard width only, with no known regional exclusions. As with any decking, local inventory can vary by length and distributor demand. Some colors may stock more readily in certain markets than others. For exact regional availability and lead times, check with a local TimberTech dealer or distributor before finalizing your build.

Which railing collections are compatible with the Terrain+ Collection®?

The Terrain+ Collection® pairs with every TimberTech Railing system, giving you flexibility across style and budget. Compatible collections include:

Impression Rail Express®

Classic Composite Series

Advantage Rail™

Pinnacle Rail®

Statement Rail™

Reliance Rail™

Fulton Rail®

The Classic Composite Series and Impression Rail Express® are especially popular pairings, often shown with Terrain+'s refined oak tones.

Can the Terrain+ Collection® be used near water? near salt water?

Yes, with the right expectations. The Terrain+ Collection® features a four-sided polymer cap with zero wood fibers, giving it strong moisture resistance and protection from mold, mildew, and rot. That makes it a dependable choice near lakefronts, pools, and other wet areas.

For dedicated dock applications, TimberTech recommends its Advanced PVC lines over Composite.

Is the Terrain+ Collection® fire resistant? Is it compliant for fire zones?

The Terrain+ Collection® is a durable composite, but it isn't one of TimberTech's fire-zone decking options. Terrain+ does not carry a Class A Flame Spread Rating, an Ignition Resistant designation, or WUI compliance.

If you're building in a wildfire-prone area, look to TimberTech's fire-resistant lineup instead:

Vintage and Landmark Collections (Advanced PVC): Ignition Resistant, Class A Flame Spread Rating, WUI Compliant

Harvest+ Collection (Advanced PVC): Class A Flame Spread Rating, WUI Compliant

Harvest Collection (Advanced PVC): Class B Flame Spread Rating, WUI Compliant

Fire-zone codes vary by jurisdiction and assembly type, so always confirm requirements with your local building official.

Are there any real woods that compare to the finish and color of the Terrain+ Collection® boards?

Yes. The Terrain+ Collection® boards offer a subtle wood grain that captures the look of sanded white oak, walnut, and sawcut pine. Our color-blending technology creates sophisticated, cascading color with a low-gloss matte finish for an authentic, refined wood look.

The three colors in the collection evoke familiar, natural wood tones:

Natural White Oak: Light, clean oak.

Weathered Oak: Soft, sun-aged gray-brown.

Dark Oak: Deep, rich brown.

Is the Terrain+ Collection® capped or uncapped? On how many sides?
The Terrain+ Collection® is a four-sided capped composite decking product. It features a proprietary polymer cap on all four sides, including inside the grooves, made with zero wood fibers. Because the cap contains no wood fibers, there's nothing on the surface to absorb water or break down. It's capped on all four sides for superior moisture resistance and lasting beauty, backed by 30-Year Product and Fade & Stain Limited Warranties.
Can the Terrain+ Collection® be used for non-deck applications? (ie. docks, porch, cladding)

The Terrain+ Collection® is built specifically as composite decking, so it isn't offered in dedicated porch or cladding formats. Those tongue-and-groove porch and cladding options come from the TimberTech Advanced PVC lines, like the Vintage and Landmark Collections.

For finishing touches, Terrain+ does offer matching fascia and riser boards in all three colors, so you can wrap your deck's perimeter and steps for a clean, seamless look.

Docks: Advanced PVC is the recommended choice for dock-style use, not composite Terrain.

Porch: Not available in the porch format.

Cladding: Not available in the cladding format.

What is the difference between the Terrain Collection® and Terrain+ Collection®?

Both are four-sided capped composite decking with the same zero-wood-fiber cap, a 30-Year Product and Fade & Stain Limited Warranty, and an upgrade value tier. The differences come down to grain, color, fire compliance, and fastener options.

Here's how they compare:

Grain and finish: Terrain has a rugged cathedral grain with an embossed texture; Terrain+ offers a subtle wood grain with a low-gloss matte finish, like sawcut pine.

Colors: Terrain comes in Brown Oak and Silver Maple; Terrain+ comes in Natural White Oak, Weathered Oak, and Dark Oak.

Fire resistance: Terrain has a Class C Flame Spread Rating and is not WUI Compliant; Terrain+ is WUI Compliant.

Fasteners: CORTEX® is not compatible with Terrain, but it is compatible with Terrain+.

Choose Terrain for a rugged, traditional grain in classic tones, or Terrain+ for a subtler grain, updated oak colors, and WUI compliance for fire zones.

Can FUSIONLoc be used for TimberTech Decking?
TimberTech no longer produces FUSIONLoc Hidden Fasteners, but they are compatible with all of our grooved deck boards.
