Walls are the largest surface of your home โ and in most older Melbourne houses theyโre empty. FreshDuct insulates existing wall cavities and new/renovated walls to create a continuous thermal barrier around your living space.
Three details and weโll call you back โ usually the same day.
Most Melbourne homes built before modern standards have empty wall cavities. Heat moves straight through them โ out in winter, in during summer โ so even a well-insulated ceiling canโt keep rooms comfortable on its own.
For existing homes we retrofit the cavity: filling it through small, tidy access points so the insulation reaches the full height of the wall. For new builds and renovations where the frame is open, we fit batts before the linings go on.
The payoff is a home that holds its temperature: fewer draughts, less noise from outside, and heating and cooling that donโt have to run as hard to keep up.

A continuous barrier across the largest surface of your home.
We identify the wall type, cavity and access, and recommend retrofit fill or batts.
Tidy access points are created (retrofit) or the open frame is prepped (new/reno).
The cavity is filled to full height, or batts are fitted snug into the frame.
Access points are made good and we confirm complete, even coverage.
A wall cavity โ before and after.
An empty cavity is a thermal shortcut straight through your wall. Filled, it becomes a continuous barrier that keeps rooms comfortable and quieter.
Certified installers, tidy roof spaces and even R-value coverage โ recent jobs across Melbourne.
Rooms stop swinging hot and cold through the day.
A filled cavity dampens traffic and street noise.
Heating and cooling donโt fight a constant loss through the walls.
Certified R6.0 batts, old-insulation removal and top-ups in the roof space.
Batts fitted between floor joists to stop cold floors and downward heat loss.
Full roof, wall and floor insulation for new builds to NCC / BASIX.
In most cases yes โ we retrofit the cavity through small, tidy access points and make good afterward. We confirm itโs suitable on a free assessment first.
Existing finished walls are usually a retrofit cavity fill. Open frames in new builds or renovations take batts before the lining goes on. We match the method to your wall.
Yes โ a filled wall cavity noticeably dampens outside noise as well as improving temperature.
Retrofit work is tidy and access points are made good. New/renovation batts are fitted while the frame is already open.
