For noise, a larger air gap between the original and secondary pane matters more than for thermal insulation, which is why acoustic secondary glazing uses a wider cavity. It is very effective against traffic and aircraft noise.
Magnetic or removable acrylic secondary panels are the cheapest and are DIY-friendly, good for renters or a budget. Fixed or sliding glass panels look better and perform best but cost more.
Secondary glazing keeps your existing windows and adds an internal pane, ideal for heritage homes and renters who cannot replace windows. It is especially effective for noise, often more than double glazing for sound.
Ways to save
- Magnetic or acrylic secondary panels are a cheap, renter-friendly, often DIY option.
- Treat the noisiest or coldest windows first if budget is limited.
- For heritage homes, secondary glazing keeps the original windows intact while improving comfort.
How we estimate this
Secondary glazing in Australia typically costs around $400 to $800 per window in 2026 for fixed or sliding glass panels, less for magnetic or acrylic panels. A whole house of 8 to 12 windows often runs $4,000 to $12,000.

What a secondary glazing costs in Hobart
A second internal pane traps a layer of still air over the existing window, and in Hobart's cool climate with cold winters that layer is bought squarely for warmth. Single-glazed colonial sashes lose heat fast on a frosty night, and secondary glazing lifts a room's comfort and cuts the heating load without replacing a window that is often part of a heritage home's value. The figure is reckoned per window on the size, the glass and the frame, so a sunroom or a tall sash window is the biggest item in a Hobart quote.
The city's weatherboard and Georgian colonial cottages are the natural candidates, their original timber windows being both the charm and the thermal weak point, and the retrofit lets owners keep them while the room finally holds its heat. Island freight is the cost variable: standard panels are made locally, but a specialty acoustic or coated unit shipped across Bass Strait carries extra cost and lead time. Condensation on cold single glass is a common Hobart winter complaint that the warmer inner pane reduces.
A glazier or secondary-glazing specialist fits the panel, not a licensed building trade, so no building licence applies while the existing opening is left intact, in Tasmania under the state building regulator for any structural side; a licensed builder is only needed if the reveal is altered. The colonial windows and any heritage listing stay untouched because nothing changes outside. Price a Hobart job by the window, the glass spec and the pane count, with freight on specialty units.

Frequently asked questions
Do I need a licence for secondary glazing in Hobart?
No. A secondary pane is fitted by a glazier or secondary-glazing specialist, not a licensed building trade, as long as the existing window is not structurally altered, in Tasmania under the state building regulator for any building side. A licensed builder is only involved if the opening is changed.
Is secondary glazing worth it in a Hobart winter?
Very much. Hobart's cold winters lose heat quickly through single-glazed colonial sashes, and the trapped air layer behind a second pane lifts room warmth, cuts the heating load and reduces the condensation on cold glass.
Can I keep my weatherboard cottage's colonial windows?
Yes, and that is the usual reason Hobart owners choose it. The second pane sits inside, the original timber sash is untouched, so a Georgian or colonial cottage keeps its windows and any heritage listing while gaining warmth.
Does island freight affect the price in Hobart?
It can. Standard panels are made locally, but a specialty acoustic or coated unit shipped across Bass Strait carries extra cost and a longer lead time, which is the main thing that moves a Hobart quote beyond the glass itself.
