KOMA Trimboards is an extruded PVC product and will not be affected by moisture. This means the boards will not warp, cup, twist, or rot. KOMA Trimboards are also impervious to salt and insects and will never need to be replaced.
This is possible because new technology has created a polyvinyl chloride (PVC) material that won't swell, rot, split, delminate, cup or craze under harsh conditions.

KOMA Trimboards match wood's ability to adapt to varying needs, but when it comes to durability, there's no comparison. Wood just doesn't stand up.
When the appearance of a natural wood grain is essential, KOMA Wood Grain Trim is the answer. This trim features full wood grain on one side and a smooth finish on the other.
