Pricing reference
How we count windows
One window opening may contain one or more window units. Bixol pricing is based on window units and cleaning complexity, not simply on the number of openings in the wall.
Raspberry-red line = a separately cleaned glass surfaceThin white line = decorative grid (no extra units)

Decorative Grids Between the Glass
Grids sealed inside the glass leave a smooth cleaning surface, so they add no units. The window is counted using its normal configuration.
