Where Can You Find Glass Pane in Taxi Boss?
You can find Glass Pane at the small construction site near 'cedar side' and at the construction site in the industrial area. Pick the site nearest you, then use its building and nearby landmarks to find the spawn area.
Construction Site Near 'Cedar Side'
Head to the small construction site near 'cedar side' and look for the unfinished building with exposed dark columns. The open ground beside the building gives you a clear approach to its interior.

Walk into the structure and look for the Glass Pane label. The material area also has Metal Pipe and Concrete Bag labels, so read the item name before choosing a spot. If you need that neighboring material too, check how to get Concrete Bag in Taxi Boss.
A countdown under Glass Pane means you're at its spawn spot while it is counting down. Wait there for the pane rather than wandering through the other material spots and losing your place.
Industrial Construction Site
In the industrial area, find the construction site beside the stacked colored shipping containers. Exposed columns, gravel piles, and low concrete sections with red edges help you recognize the area.

Check the material spawn area around the unfinished structure for Glass Pane. Metal Pipes also appear here, so keep looking for the Glass Pane label rather than stopping at the first material pickup.

Once you collect your Glass Pane, you have the material you came for. If your next search is another building material, follow the Taxi Boss wood planks locations or learn how to pick up sand in Taxi Boss before heading to the next pickup.
