The 30-Second Verdict
Both are excellent composite decking brands for Florida. TimberTech (AZEK) edges out Trex in heat resistance (critical in Florida summers) and uses full PVC cap rather than composite core on premium lines, making it more moisture-resistant. Trex offers better value at mid-grade and has a larger dealer network. For South Florida or pool decks, TimberTech AZEK premium lines are worth the premium.
