KOMA PVC corner boards 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 plastic corners won’t swell, rot, split, delaminate, cup or craze, even under the harshest of conditions. The secret is our unique Celuka extrusion process that delivers the hardest surface in the industry, and the most exacting thicknesses ever manufactured.
You’ll 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 corner board using their regular tools. And while KOMA exterior PVC corner boards are UV-resistant, and require no paint for protection, the special proprietary surface provides excellent adhesion to any custom 100% acrylic latex paint color with a value of #55 or higher on the Light Reflective Value scale.
All KOMA PVC corner boards come shrink-wrapped in tight, thick, 2mm specialty polymer blend film that resists puncturing, tearing and zippering and is UV-stabilized for extended storage.
