CompositWood is made from a proprietary mix of specialty polymer and acrylic resins, creating an “engineered composite”, super tough, solid core material.

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.

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 “SuperCap™” 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.

Why CompositWood?

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.

  • Classic wood window designed frame and sash for added elegance
  • Solid core frame and sash for superior thermal performance and strength
  • Draftblocker™ off-set compression sash design for air-tight seal and added security.
  • Integral off-set balance pockets and multiple weather-strip paths to reduce air infiltration
  • Tripled-secured sash & frame corners: mortise & tenon joined and chemically welded sash, fusion welded frame, stainless-steel screw fastened
  • Lift-out sashes for easy cleaning from inside your home
  • MAX Glass option provides a larger glass viewing area.

Climaguard™ Low E Glass and Argon Gas Add Comfort and Energy Savings

Low E is a transparent metallic oxide coating applied onto a glass surface. The coating allows short-wave energy to pass through but reflects long-wave infrared energy, which lowers the U-value and that means more energy savings. An odorless, colorless, tasteless, non-toxic gas, argon is six times denser than air. It is used to replace air between the glass panes to reduce thermal energy transfer and heat loss.

ClimaGuard glass has heat reflective coatings – microscopically thin layers of metal and metal oxide that filter energy by keeping warmth inside in winter and outside in summer.
