AZEK vs TimberTech Composite

Both are made by the same manufacturer. The difference is the core. TimberTech uses a composite core with wood fiber. AZEK uses full PVC with no organic content. AZEK costs more but delivers superior moisture performance and a longer warranty. For most Seattle residential applications, TimberTech composite is the practical choice. For pool decks, waterfront builds, or homeowners who want the absolute best, AZEK is the answer.
