Common operating styles
- Sliding windows: simple horizontal operation and broad glass area
- Single hung and double hung windows: vertical operation with a familiar profile
- Casement windows: hinged operation with broad ventilation when open
- Awning windows: hinged at the top and often used for controlled ventilation
- Picture windows: fixed glass for light and views without ventilation
- Specialty shapes: fixed or operating units designed for a particular opening
Manufacturers, frames, and glass
Frame material affects profile, maintenance, color, rigidity, thermal behavior, and cost. Glass choices can affect insulation, solar heat gain, visible light, privacy, safety, sound, and security. The right combination depends on the opening and the goal.
Glass Pro's uses Alside and Lindsay windows. Patio door projects use WinDor systems in aluminum and vinyl. The estimate identifies the exact manufacturer, product series, frame, glass, color, and configuration proposed for the opening.
Bring the decision back to the room
Consider how you will reach, open, clean, and shade the window. Furniture, sun exposure, and weather also affect which features will be useful.
