TIMBERTECH ADVANCED PVC COLLECTIONS

TimberTech Advanced PVC has an exclusive selection of natural, realistic styles, and no two boards look exactly alike. It’s all thanks to TimberTech’s advanced color technology, which delivers a wide range of natural textures and subtle, multitonal colors — for authentic wood looks you can’t find anywhere else.

Vintage Collection | Advanced PVC

Give your clients the look of sought-after premium hardwoods like ipe, mahogany, and teak with the Vintage Collection. Featuring a refined wire-brushed finish and multitoned color blending with highlights and lowlights, this collection delivers a truly authentic wood look.

LANDMARK COLLECTION | Advanced PVC

For a look that resembles popular hardwoods like white oak and walnut, choose the Landmark Collection. Featuring a crosscut cathedral grain with a matte finish and cascading color blending, this collection is perfect for clients looking for a character-rich style.

HARVEST+ COLLECTION | Advanced PVC

Bring the character of gently worn hardwoods to any outdoor space. Harvest+ features blended colors with subtle highlights, lowlights, and tonal variations — plus artfully layered open and cathedral grain patterns with a low-gloss finish. This collection has the look of a beautifully aged patina for a natural, lived-in feel.

HARVEST COLLECTION | Advanced PVC

Introduce your clients to the inviting versatility of the Harvest Collection, featuring an attractive cathedral grain and soft, solid colors that suit a range of styles. TimberTech’s capped polymer decking delivers sophisticated, real wood aesthetics they’ll never have to sand, stain, or seal.

PORCH COLLECTION | Advanced PVC

Bring all the real wood looks and performance benefits of TimberTech Advanced PVC Decking to your clients’ porches. The innovative tongue-and-groove installation allows for smaller gaps between boards — delivering a traditional hardwood flooring look your clients will love.

TIMBERTECH COMPOSITE COLLECTIONS

Not all composites are created equal. TimberTech’s range of real wood looks is unmatched, and their protective cap resists moisture and locks in rich color—so your customer’s decks will continue to look and perform beautifully without the costly, time-consuming maintenance of wood.

Legacy Collection | Composite

Choose the Legacy Collection for an artisanal, craftsman-inspired look. With cascading hues, a textured, hand-scraped finish, and a variable grain pattern, each board is unique — perfect for clients wanting a one-of-a-kind deck.

RESERVE COLLECTION | COMPOSITE

For clients looking to capture the character rich look and feel of reclaimed wood, go with the Reserve Collection. These boards feature bold, cascading colors, a rustic cathedral grain,
and a wire-brushed finish.

TERRAIN+ COLLECTION | COMPOSITE

The new Terrain+ Collection is perfect for your customers who want maximum style for their dollar. It features the same lightweight, scalloped profile, but with an updated color palette. These boards deliver sophisticated colors with a subtle grain pattern like sanded white oak and walnut for a natural wood look.

TERRAIN COLLECTION | COMPOSITE

Embrace a timeless, authentic wood look with the subtle coloring and rugged cathedral grain of the Terrain Collection. Clients can choose from boards with varied color blending or those with a solid, stained wood look. Plus, with their scalloped profile, these boards are lighter in weight for easier installation

PREMIER COLLECTION | COMPOSITE

For an opaque stained or painted wood look in a solid-profile board, introduce clients to the Premier Collection, which features earthy, vivid wood stain colors and a subtle straight grain pattern.

PRIME+ COLLECTION | COMPOSITE

Opt for a simple, traditional wood look with the natural, inviting colors and textured straight grain pattern of the Prime+ Collection. The authentic wood styling, minimal maintenance needs, and attainable price point make this collection the ideal choice for clients looking to upgrade from wood.

PRIME COLLECTION | COMPOSITE

The Prime Collection features the same painted wood look as the Premier Collection, but with a scalloped board for a lighter weight without compromising a secure underfoot feel.
