CompositWood+ Bow & Bay Windows
CompositWood+, the next generation of windows, is a revolutionary material blended with timeless design that surpasses the ambitions of even the most well known window manufacturers.
Nothing defines a home like the elegance and warmth of wood windows, but the maintenance problems and expenses associated with wood are simply overwhelming.
Metal and vinyl clad wood windows were only partial solutions. In the industry-wide pursuit of window excellence, CompositWood+ is the answer.
What is CompositWood+?
CompositWood+ is made from a proprietary mix of specialty polymer and acrylic resins, creating an “engineered composite”, super tough, solid core material. A permanent color surface technology called ToughCoat™ is fused to the core materials during the extrusion process.
CompositWood+ is simply the best window you can buy. It provides the warmth of a finely milled wood window without the problems associated with wood.
