Why is purified water used for washing glass in sealed unit production?

Using purified water for sealed units ensures that no impurities, limescale, or residues remain on the glass before assembly. This improves adhesion when applying the spacer and sealant. At Glasscraft, our purified water for sealed units is treated through reverse osmosis, similar to desalination plants, ensuring a spotless and contaminant-free surface. High quality purified water for sealed units results in a longer-lasting and more efficient window.
