- Light reflection
- The percentage of light reflected by the exterior surface of the glass.
- Light transmission
- The percentage of external light that passes through the glass. The higher the percentage the more daylight that will enter your home.
- Lintel
- A horizontal framing member placed across the top of the rough opening of a window or door to prevent the weight of the wall or roof from resting on the window frame.
- Lite/light
- A window or other construction which allows light into a room. Also denotes the sections into which a sash is subdivided by glazing bars.
- Louvre
- An opening with horizontal slats to permit passage of air and gives reasonable weather protection. Available with timber, glass or metal slats.

- The percentage of directly transmitted heat plus the absorbed and inwardly re-radiated heat, that passes through the glass. If cooling is paramount, a lower solar transmission is better.
- Sound transmission class (STC)
- A rating for the efficiency of building materials and elements to reduce the transmission of sound. It is expressed in decibels (dB) and the larger the number the better the reduction in noise passing through the material or element.

- Textured glass
- Textured glass incorporates textures and opaqueness within the glass to create privacy or design elements.

- Transom
- A horizontal framing member between a window or door and a lowlite.
- Tricia
- Refers to a style of showerscreen. Based on a two sided screen - panels at right angles - with a third panel, usually the door, cut across the corner.
- UV transmission
- The percentage of ultraviolet light that passes through the glass. The lower the percentage, the better protection for furnishings and carpets from fading.
- U Value
- A measurement of the rate of heat flow through the glass. The lower the U-value the better the glass is at insulating. Glass with a low U-value is generally used to keep the warmth in a room in cold climates.

- A material or device used to seal the openings, gaps or cracks of operable window and door units to prevent water and air penetration.
- Weep hole
- A small hole which permits water to drain off.
