LAP SIDING
& TRIM SYSTEM

The Trim Matters

AZEK Trim adds a nice aesthetic and protects the exterior from moisture. Unlike wood and other materials that absorb a high percentage of their weight in water, AZEK PVC absorbs almost nothing. AZEK boards are 100% protected from both water exposure and absorption.
