Testing indicates that composite materials have excellent long-term durability. However, their use for window applications is relatively new; installation in housing started in the mid-1990s.
Composite frames, due to their dimensional stability, can provide superior resistance against air infiltration, in addition to thermal resistance (through the frame) comparable to wood.
By taking advantage of the properties of various products, composite window frames offer a dimensionally stable, energy-efficient product that is resistant to warping, fading, and denting.
Composite frames offer high impact resistance.
Ease of Implementation
Composite window frames are currently available in many styles, sizes and colors for new or replacement applications through local distributors.
Windows featuring composite frames cost more than vinyl window frames but less than clad wood windows.
Operational cost is comparable to other maintenance-free windows having comparable energy ratings.
All windows must be tested and certified for compliance with applicable standards. American Architectural Manufacturers Association (AAMA), National Fenestration Rating Council (NFRC), and EnergyStar all have standards for Composite Window Frames.
Composite frame windows are currently available for new or replacement applications. Manufacturers’ installation instructions are similar to those of other windows.
The use of composite plastics reduces the use of natural resources, and the frames are easily recyclable. Composite windows are low maintenance, are resistant to fading, have high insulation properties and dimensional stability. The window frames are available in many different colors.
