Window sashes are typically made of wood, vinyl or aluminum.
- Wood is the strongest and best natural insulator available, and it is easy to use. Wood is typically also the most expensive. The most significant disadvantage is that wood can decay or be damaged by insects. It must be painted. Pine or spruce is used for most wood windows.
- Vinyl does not rot, rust, flake, corrode and is low maintenance. With improved technology, vinyl is fast approaching wood in efficiency. One variation to the vinyl window is the vinyl-clad window. Here, vinyl is applied over the base material, usually metal. Windows with welded frames are sturdier and more energy efficient than frames that are screwed together.
- Aluminum is the least expensive window material, but is also weak and doesn't hold fasteners well. In addition, it is a poor insulator. Aluminum window frames compensate for these deficiencies by using gussets at the corners of the frame to keep it from cracking and thermal breaks in the sash and frames to reduce heat transfer.
