Low-Iron Shower Glass and Nano Coating: Keep Clarity and Protection Separate
Low-iron glass describes the glazing choice, while a surface coating describes a treatment. Confirm the actual pane and any factory treatment before planning nano coating.

Identify the supplied glazing
Use the enclosure or glazing documents to identify the product. Record whether a factory coating is already present and which face carries it. Do not infer the full specification from the apparent colour of the glass edge.
Define the coating objective
Discuss maintenance, surface condition and the intended application separately from the glass selection. A nano coating trial should not be presented as converting standard glass into low-iron glass or repairing an underlying glazing difference.
Evaluate the actual surface
Follow the glass supplier’s care guidance and confirm compatibility for the proposed coating. Inspect preparation and the accepted dry appearance on a representative area. A clean-looking new pane can still have a treatment history relevant to the process.
Keep the care information together
Retain glazing identification, coating product and treated-face information in one record. Pilkington’s OptiShower documentation, for example, describes a specific factory-coated glass and a low-iron option; its care method applies to that named product, not automatically to every shower pane.
Frequently asked question
Does low-iron glass mean no factory coating is present?
No. Confirm the supplied glazing specification and exposed surface treatment rather than using the glass description alone.
