The 30-Second Verdict
AZEK (all-PVC core) handles Florida's heat and moisture better than Trex (wood-composite); it's also more expensive. Trex Transcend is the closest Trex product to AZEK's performance level. For Florida's intense sun and humidity, AZEK's advantage is meaningful.

Frequently Asked Questions
Does composite decking get too hot to walk on barefoot in Florida?
Both Trex and AZEK can get uncomfortably hot in Florida's direct summer sun—composite decking absorbs more heat than wood and significantly more than pool coping or tile. Light-colored boards stay noticeably cooler than dark colors. For pool deck applications, composite decking is generally not recommended in full-sun areas where barefoot walking is expected—tile or cool-deck coated concrete is more appropriate.
How long does Trex or AZEK last in Florida?
Both should last 25-30+ years in Florida with basic maintenance. Trex Transcend and AZEK TimberTech are both backed by 25-30 year warranties against fading, staining, and defects. The greater risk for Florida composite decking longevity is the subframe—use pressure-treated lumber or hidden fastener systems, and ensure proper ventilation under the deck to prevent moisture accumulation in the joist system.
What composite decking is most common in Florida?
Trex holds the largest market share in Florida as nationally. Within Trex's line, Trex Transcend and Trex Enhance are the most common Florida installations. AZEK/TimberTech is a popular upgrade option, particularly around pool areas and in high-humidity coastal environments where its moisture-proof construction provides a meaningful advantage.
