- Low-E Glass: Coated to show heat back into the room, enhancing thermal effectiveness.
- Obscured Glass: For personal privacy in restrooms or ground-floor systems.
2. Frame Type and Material

To get a precise quote, one should choose which practical style best fits the space's needs. Each type brings a different price point based upon the hardware and engineering involved.
- Fixed Units: These remain permanently in location. They are the most cost effective option however are just suitable for windows that do not need to be opened for ventilation or cleansing.
- Lift-Out Units: These panels can be physically eliminated from the frame. They offer a balance between the low expense of fixed units and the necessity of occasional access to the primary window.

- Vertical Sliders: Designed to match the meeting rails of conventional sash windows. These are frequently the most expensive due to the spring-balance mechanisms required to hold the glass at different heights.
- Hinged Units: These open like a basic door or window. They are frequently utilized when total access to the main window is required regularly.
