Translucent fiberglass panels
Translucent fiberglass panels are an excellent way to allow natural light into a metal workshop building. These panels can be installed on the upper section of an exterior wall or in the roof area.

Translucent panels can be made to be insulated and non insulated. For roof top installations, it's best to use the insulated panels if your building is also insulated. This will limit heat loss or gain through the insulated panel. Insulated panels cost about double as non-insulated. They are basically two single panels that are sandwiched together so that there is an insulating air space between.
If you are designing a metal building that will have an open area, installing translucent fiberglass panels will quickly pay off by reducing overhead lighting needs.
