Double glazing in Hobart.
Hobart is the coldest capital in the country, and single glass leaks that hard-won heating straight out the window all winter. Double-glazed insulated units halve the heat lost through the glass, stop the morning condensation, and quieten the house. Retrofit into existing frames or fit to a new build.
Why double glazing earns its keep in Hobart.
Heat moves through a single 4mm pane of glass quickly, and Hobart asks a lot of its heating. Long, cold winters mean a single-glazed home is fighting the cold from May through September, with the heater working against glass that may as well be an open vent. A double-glazed insulated glass unit traps a layer of air or argon between two panes, roughly halving the heat lost through the glass and letting the room hold the warmth you have paid to put into it.
The other thing every Hobart homeowner notices is condensation. On a frosty Sandy Bay or West Hobart morning, single glass runs with water on the inside, which pools on sills, marks paint and feeds mould. Because the inner pane of a double-glazed unit stays much closer to room temperature, that condensation largely disappears. The third benefit is noise: a double-glazed or laminated unit noticeably cuts road and wind noise, which matters on busier streets in Glenorchy, Moonah and along the main roads.
Options we fit.
- Insulated glass unit (IGU) replacement: new double-glazed unit into your existing frame where it suits the frame.
- Full retrofit: reglazing timber or aluminium sashes to take a double-glazed unit, common in older Hobart homes.
- Secondary glazing: a discreet second pane fitted inside the existing window, ideal for heritage homes where the original sash must stay.
- Low-E coatings: a heat-reflective coating that pushes winter warmth back into the room, well suited to Hobart’s heating-dominated climate.
- Argon fill and laminated options: for extra thermal and acoustic performance on exposed or noisy elevations.
A worked example.
A West Hobart weatherboard with eight single-glazed timber-sash windows, all running with condensation each winter. We retrofit double-glazed units into the existing sashes at roughly $1,100 per window, around $8,800 for the eight, fixed and written after the measure. The owner keeps the heritage look, loses the condensation, and runs the heater a lot less.
