Trex Select Decking

Trex Select delivers what Montana contractors need: composite decking that stays up to 37°F cooler than traditional options, backed by a 35-year warranty. This mid-tier composite line uses 95% recycled content and features SunComfortable™ Technology — critical for decks that bake in Montana’s high-elevation summer sun.

At 1-inch by 6-inch boards available in 12, 16, and 20-foot lengths, Select fits standard framing layouts. The grooved edge profile works with hidden fasteners for a clean surface, while square-edge boards handle stairs and picture frames.

Thermal Performance and Weather Resistance

The SunComfortable™ Technology keeps boards up to 37°F cooler than traditional composite. That’s the difference between barefoot-comfortable and egg-frying hot on a July afternoon in the Mission Valley. The submersible, waterproof design handles spring snowmelt without drama.

Select resists fading, staining, mold, and mildew through its high-performance protective shell. The 35-year fade and stain warranty covers Montana’s intense UV exposure at elevation. Consumer Reports testing confirms strong resistance to flexing, slipping, staining, surface damage, and weathering, with high friction ratings for slip resistance.

Installation and Specifications

Select cuts and drills like wood with standard tools. No special blades needed. The flexible boards conform to minor framing variations — forgiving when that rim joist isn’t perfectly straight.

Value Comparison

Select sits between Enhance and Transcend in the Trex lineup. Select features a solid profile and 35-year warranty, while Enhance uses a scalloped bottom for economy and carries a 25-year warranty. That solid profile matters — no hollow spots to trap moisture or weaken under snow load.

The boards measure 7/8-inch thick rather than the full 1-inch of some competitors, but the solid bottom construction provides durability and scratch resistance. The 95% recycled content matches Trex’s premium lines — you’re not sacrificing environmental credentials for the mid-tier price.

Professional contractors appreciate Select’s durability against weather, stains, and mold, plus the natural wood-like appearance with a soft, splinter-free finish. Reviews from 190 users average 4.5 stars, praising how the flexible boards are “very nice to work with” and “easy to cut and install”.

FAQ

How much cooler does Trex Select really stay compared to other composites? SunComfortable™ Technology reduces surface temperature by up to 37°F compared to traditional composite decking. The technology works — barefoot-testable on any sunny afternoon.

What fasteners work with the grooved-edge boards? Select’s grooved edges are compatible with hidden deck fasteners including Trex Hideaway. Standard composite decking screws also work. Using proper manufacturer-specified fasteners is required for warranty compliance.

Can Select boards handle Montana’s freeze-thaw cycles? The boards are submersible and waterproof, designed to handle moisture without degrading. The protective shell resists mold and mildew that typically attack wet lumber. Consumer Reports testing confirms strong weathering resistance.

What’s the real difference between Select’s 35-year and Enhance’s 25-year warranty? Select uses a solid profile while Enhance has a scalloped (hollowed) bottom. That solid construction handles snow loads better and provides the extra decade of warranty coverage. The 35-year fade and stain protection covers the brutal UV exposure Montana decks endure.
