Morphology
The meaning 'a window with two layers of glass...' is directly derivable from 'double' (twofold) and 'glazing' (glass/window glazing). This is a regular compositional compound with clear cross-linguistic parallels (e.g., French double vitrage, Spanish doble acristalamiento), so a B1 learner who knows both constituents will readily infer the MWE meaning.
Etymology
Double glazing is named for its two layers of glass: double means two and glazing means the glass part. The small space between the panes traps air and helps keep heat in and noise out, so the name came to mean 'reduces heat loss and noise'.
