Double Glazed Window Installation and Retrofit FAQs
Can any existing window be retrofitted with double glazing?
Not all windows are suitable for retrofit double glazing. Frame condition, depth and hardware all
matter. Some older frames may require full replacement. A glazing specialist can review photos and,
if needed, inspect on site to advise which windows can be retrofitted and which are better replaced.
Will double glazing stop condensation completely?
Double glazing can reduce condensation on interior glass surfaces by keeping the inside pane
warmer, but moisture levels, ventilation and lifestyle still play a role. In some situations, you
may still see condensation at times. Your tradie can discuss realistic expectations for your
climate and home design.
Does double glazing always improve noise levels?
Many double glazed systems improve noise compared with single glass, especially when using
different glass thicknesses or acoustic units. However the frame type, seals and wall construction
also matter. Your glazing specialist can discuss options where noise is your main concern, and how
double glazing fits into a wider noise reduction plan.
Do I need to change my existing blinds or curtains?
Often existing window coverings can stay, but deeper frames or new opening directions can affect
some fittings. It is a good idea to mention any shutters, pelmets or recessed blinds so your tradie
can factor them in when planning the upgrade.
