Celuka example


In the unique KOMA Celuka process, special extrusion tooling allows for quick cooling of the outer surface of the Celuka PVC material, and an inward expansion of the cellular PVC, resulting in a product profile with a hard, smooth outer surface and a strong cellular core.

Extruding the PVC around a torpedo-shaped device, and water-cooling, is what adds hardness in the Celuka process, and one reason we can confidently state KOMA Celuka cellular PVC lumber is the hardest surface in the industry. It also has the most exacting thicknesses ever manufactured.

You'll immediately notice the difference upon delivery, with no mars, dents or scratches. Builders will experience the KOMA difference as they nail, glue, drill, rout, and cut our trim products using their regular tools.

All KOMA products, look, feel and work just like high-quality wood, but are impervious to moisture, insects, and just about anything else Mother Nature can deal out. KOMA products won't swell, rot, split, delaminate, cup or craze, even under the harshest of conditions.
