What are Brewster Fringes?

What Are Brewster fringes

“Under certain lighting conditions, Brewsters fringes are sometimes visible when multiple light reflections occur in IGUs of high-quality float glass panes of identical thickness (for example 4 mm float on 4 mm float from the same stock sheet).

These interference fringes are faint coloured bands of irregular shapes, and they can be located anywhere over the surface.

These fringes are not considered a defect.”Download the IGUs in residential buildings – a guide to quality standards.pdf
