Decking Materials in the Trex vs TimberTech Glossary
Most of the confusion in a trex vs timbertech glossary comes down to what the boards are made of, so start here. Both brands build boards differently across their lineups, and those differences drive price, looks, and how the deck ages through Ohio winters.
Composite Decking
Composite decking is board material made from a blend of wood fibers and recycled plastic, pressed into deck boards. It resists rot and insects better than treated wood decking and never needs staining or sealing. For Cincinnati homeowners, that matters because our freeze-thaw cycles are hard on bare wood. When a deck contractor quotes composite, expect a higher material cost up front and lower upkeep over the life of the deck.
Capped Composite
A capped composite board is a composite board wrapped in a tough plastic shell that protects against stains, fading, and moisture. The cap is what separates modern composite decking from the older, uncapped boards that earned a bad reputation for mold and fading. Some boards are capped on three sides, others on all four. Ask your deck builder which type a quote includes, because the cap is doing most of the long-term work.
PVC Decking
PVC decking means boards made entirely of plastic, with no wood fibers at all. With no wood inside, there is nothing to absorb water, which makes PVC a common pick for pool deck installation and other wet spots. It usually costs more than standard composite. If a quote jumps in price between two board lines, PVC content is often the reason.
Capped Polymer
Capped polymer is the industry's term for an all-plastic board core wrapped in a protective outer shell. You will see this phrase on premium product lines, and it is essentially PVC decking with a cap, the same way capped composite is wood-plastic with a cap. Knowing the term keeps you from paying for a label you don't understand. It also tells you the quote is pulling from the top of a brand's lineup.
Board Profile
A board profile is the cross-section shape of a deck board, including its thickness, width, and whether the underside is solid or ridged. Profiles vary between product lines even within one brand. Thicker, solid profiles feel stiffer underfoot and cost more. If two quotes name different lines from the same brand, the profile is one of the things you are actually comparing.
Scalloped Board
A scalloped board is a composite deck board with ridges or channels on its underside that reduce weight and material cost. Scalloped boards are common in entry-level lines, while premium lines run solid. The walking surface looks the same from above. The practical difference shows at cut ends and stair edges, where a scalloped underside may need a trim piece to hide the channels.
Heat Retention
Heat retention means how much warmth a deck board absorbs and holds when it sits in direct sun. Darker boards and some plastic-heavy formulas run hotter underfoot, which matters for a south-facing deck or a pool deck where kids go barefoot. Both major brands publish lighter-colored options for sunny spots. Ask your deck builder which colors stay cooler if your yard gets full afternoon sun.
Installation and Structure Terms in Trex vs TimberTech Specifications
These are the words that show up once a deck contractor starts talking about how the deck goes together, not just what it looks like.
Grooved vs. Square-Edge Boards
Grooved boards have a channel cut into each side edge to accept hidden fastener clips, while square-edge boards have flat sides and get screwed down from the top. Most of the deck field uses grooved boards, and square-edge boards handle stairs, borders, and exposed ends. A quote that lists both is a sign the builder is planning the layout properly. It is a detail worth seeing in writing.
Hidden Fasteners
Hidden fasteners are clips that attach deck boards to the frame from between the boards, so no screw heads show on the walking surface. They give a cleaner look and set consistent gaps between boards, which helps water drain through. They add a little to material cost and labor. If a low quote skips them and plans to face-screw composite, ask how the builder will hide or plug the screw heads.
Picture Framing
Picture framing is a design detail where a border board runs around the outer edge of the deck, framing the field boards like a picture. It hides the cut ends of boards and gives the deck a finished, custom look. It also adds labor and sometimes extra framing underneath. When a custom deck design quote includes picture framing, that line explains part of the price difference from a plain layout.
Multi-Width Decking
Multi-width decking means a product line offered in more than one board width, so a builder can mix wide and narrow boards in one design. Mixing widths creates patterns you can't get from a single-width line. Not every tier in every brand offers it. If a design rendering shows mixed widths, confirm the quoted product line actually comes in those sizes.
Substructure
A substructure is the frame of posts, beams, and joists that holds up the deck boards you walk on. Composite boards can outlast a wood frame, so the condition of the substructure decides whether you can reuse it. In greater Cincinnati, footings also have to sit below frost depth so freeze-thaw cycles don't heave the deck; your builder and local permit office confirm the specifics. A good quote describes the substructure, not just the boards.
Joist Spacing
Joist spacing is the distance between the frame boards that support the decking, measured center to center. Composite boards usually need closer joist spacing than treated wood, and diagonal board patterns need closer spacing still. Each manufacturer publishes its own spacing requirements, and ignoring them can void the warranty. If you are resurfacing an older deck, the existing spacing may limit which boards you can use.
Deck Resurfacing
Deck resurfacing means removing the old deck boards and railing while keeping the existing frame, then installing new decking on top of it. It can be a cost-saving path to a composite deck if the substructure is still sound. A deck builder should inspect the frame first, because rotted joists or wide spacing can rule it out. If a quote offers resurfacing without an inspection, push back.
Pricing, Warranties, and Product Lines
Product Tiers
Product tiers are the good, better, and best lines a decking brand sells, each with different materials, caps, colors, and prices. Both major composite brands organize their catalogs this way, which is why two quotes for the same brand can land far apart. Always compare tier to tier, not brand to brand. Our Trex vs. TimberTech cost guide for Cincinnati walks through how the tiers line up against each other.
Fade and Stain Warranty
A fade and stain warranty is the manufacturer's written promise that the board's color won't fade beyond a stated amount and that common spills won't leave permanent stains, for a set number of years. It is separate from the structural warranty on the board itself and separate from the builder's workmanship warranty. Warranty length and terms vary by product tier. Read what the warranty excludes, since it can require proper joist spacing and approved fasteners.
Linear Foot vs. Square Foot Pricing
Linear foot pricing measures cost per running foot of material, while square foot pricing measures cost per foot of finished deck area. Lumberyards often price boards by the linear foot, and deck builders often quote whole projects by the square foot. Mixing the two is the fastest way to misread a quote. When comparing bids on the trex vs timbertech question, make sure every number uses the same unit before you compare.
Installed Cost
Installed cost means the full price of the finished deck, including boards, substructure, railing, fasteners, labor, and demolition of any old deck. Board price alone tells you little, because labor and framing make up a large share of any deck building project. Two brands with similar board prices can produce different installed costs depending on fastening systems and framing requirements. Ask every deck contractor for an itemized installed cost so you compare complete numbers.
Using These Terms
You now know what the spec sheets and estimates are actually saying. What this trex vs timbertech glossary gives you is the ability to read a quote line by line, match each term to a real decision, and ask a deck builder specific questions about caps, tiers, fasteners, and framing. That conversation gets a lot shorter, and a lot more useful, when both sides are speaking the same language.
