WINDOW TYPES
Window types and frame materials explained
Style affects operation and appearance; material affects maintenance, design options, performance and price.
Common operating styles
The best style depends on ventilation, opening size, cleaning access, architectural fit and how the space is used.
- Single-hung and double-hung
- Casement and awning
- Sliding windows
- Picture and fixed windows
- Bay and bow configurations
- Specialty shapes
Common frame materials
Vinyl is widely used for low-maintenance projects. Fiberglass can offer strength and stability. Wood offers traditional appearance and finishing options. Aluminum is slim and durable. Composite products vary by manufacturer.
Compare the complete assembly
Do not choose on frame material alone. Glass, spacers, weatherstripping, hardware, reinforcement, installation and warranty all contribute to the finished project.
