Trex vs TimberTech vs Deckorators for Idaho Decks

The clearest structural difference is material composition. Most Trex lines and the TimberTech Composite collections are wood-plastic composites with a protective cap; Trex Refuge is a solid-profile PVC board. TimberTech also produces an Advanced PVC range with no wood flour in the board at all, which is a genuinely different material rather than a premium version of the same one. Deckorators' mineral-based lines — including Voyage, Vault and Summit — use a mineral-based composite the company calls Surestone, which is again a different composition from conventional wood-plastic composite. These differences show up in weight, in moisture behaviour, in heat behaviour and in the warranty terms each manufacturer is prepared to publish.

It depends on which aspect you weigh, because the brands structure their warranties differently. TimberTech's Advanced PVC collections carry a limited lifetime product warranty, with a 50-year fade and stain term on Harvest, Harvest+, Landmark and Vintage and 35 years on Solstice. Trex publishes 50-year limited residential warranties on Signature, Transcend Lineage, Transcend and Refuge, 35 years on Select and 25 years on Enhance. Deckorators publishes a 50-year structural term with 25-year stain and fade on Voyage and Vault (Voyage adds 25-year removal and replacement), and 25 years on Summit and Venture. Compare the fade and stain term separately from the structural term, and check proration and transferability — they are not the same promise.

All composite and PVC decking gets hot in direct sun, and no manufacturer claims otherwise. Surface temperature is driven mainly by colour and by direct exposure — darker boards run hotter than lighter ones across every brand. Some lines are marketed on cooler surface performance — Trex lists heat-mitigating technology on Transcend Lineage and on five Enhance colours — but the practical levers available to you are colour selection and shade. In the Treasure Valley, where summer sun is intense and decks are often unshaded, choosing a lighter colour is usually more effective than choosing a different brand.

Yes, and this matters enormously if you are resurfacing an existing frame. Joist spacing requirements, span limits, fastening methods and gapping are set by each manufacturer for each specific product, and they differ between brands and between lines within a brand. Diagonal board layouts reduce permitted spacing further. Installing outside the published requirements can void the warranty regardless of workmanship quality. Always check the installation instructions for the exact product before committing, particularly when the existing frame was built for traditional wood decking.

It is meaningful but narrower than it sounds, and reading the definition matters. Manufacturers define fade in measurable terms — Trex, TimberTech and Deckorators all reference a colour change threshold of 5 Delta E (CIE) units (Trex allows up to 15 Delta E after year 25) — rather than as a subjective judgement, and they are explicit that no material is fade-proof after years of UV exposure. Transferability differs: Trex and TimberTech permit a single transfer within five years of original purchase, while Deckorators' decking warranty is non-assignable to subsequent owners. Read the actual warranty document for the specific line rather than the marketing summary, because coverage, proration and exclusions all vary.

There is no universal winner, and any contractor who names one without asking about your deck is not answering the question. The relevant inputs are your sun exposure and preferred colour, whether you are building new or resurfacing an existing frame, how the deck will be used, which warranty aspect matters most to you, and the availability and price of specific lines locally. Iron Crest builds with products selected against those inputs rather than a single house brand, and we will show you the published requirements and warranty terms for whatever you are considering.
