Frequently asked questions
Is double glazing worth it in Adelaide’s climate?
For many homes, yes. Adelaide’s hot summers and cold mornings mean double glazing can reduce heating and cooling running costs and noticeably improve comfort, especially in west-facing rooms. The size of the saving depends on the home, the existing windows and how you heat and cool it.
Can existing windows be retrofitted with double glazing?
In many cases yes — particularly timber-framed sash windows where the existing frame can accept a thicker glazing unit. Aluminium frames usually require full replacement.
How long until double glazing pays back?
Payback varies widely with the home, the existing windows, orientation and energy use, so treat any single payback figure with caution. Comfort and noise-reduction benefits start day one.
How much does double glazing cost in Adelaide?
As a typical guide for Adelaide homes: $1,500–$8,500 per opening fitted for full double-glazed window replacement, depending on size and frame, and $1,800–$4,000 per opening for retrofit double-glazed sashes. Your written quote after the on-site measure sets out the exact price, line by line.
