The wall solution

ComfortWall™ Cavity Insulation sets a new standard for comfort and cost savings, protecting your family from noise, fire and dampness – and the extremes of winter and summer.

Originally inspired by the way wind spins molten lava into a web of stonewool, ComfortWall is made from the renewable resource of volcanic rock. Free from harmful chemicals, it is the world’s most trusted natural insulation.

ComfortWall is pumped into the wall cavity with the same certified and proven technology used in millions of European homes for over 50 years.

Unlike other insulations, it is installed by specialist technicians to strict quality control standards and comes with an installed performance warranty.

The whole solution

ComfortWall representatives are trained to consider the comfort and sustainability of your new home as a whole.

Quiet, Safe, Comfortable, Healthy


Brick walls are good at stopping noise, but an unfilled cavity allows sound to travel along it from room to room. The open tops of walls and the small gaps around windows and doors are weak points and allow noise to enter your home. ComfortWall absorbs this cavity noise, adding quietness to your home.


ComfortWall is one of the only insulations that the Building Code of Australia classifies as non-combustible – it cannot burn. If the plumber needs to weld a leaking pipe or an electrical wire shorts, the insulation will keep you safe. If you live in a bushfire prone area, there is no risk of flying embers igniting the insulation.


ComfortWall performs where you need it most, insulating you from hot western walls that radiate unbearable summer heat into bedrooms throughout the day and long into the night – or cold southern walls that never see the sun and keep rooms cold, damp and musty throughtout the winter.


ComfortWall fills the brick cavity and fits snugly around wire ties and pipes. For over 50 years the unique stone wool structure has been proven to allow walls to breathe whilst also providing a highly effective water barrier. Being made from rock, it will never rot or decay.

cost savings

How much does a new
home really cost?

Whilst the Building Code of Australia (BCA) requires a new home to achieve a 6-Star rating, this minimum standard can be achieved with the only insulation being in the roof – but still result in power costs of $12,000-$16,000 over 10 years.

Research shows that ComfortWall reduces heat flowing through double brick walls against heat and cold by 65%, amd improves the overall home by up to 20% – making it much cooler in summer and warmer in winter.

Just like your home, your investment in wall insulation should stand the test of time.

Unlike ‘shiny’ reflective foil insulation, the performance of ComfortWall is not affected by how carefully or correctly the bricklayer installed it, the daily temperature changes, air drafts or loss of ‘shininess’ caused by tarnishing and accumulation of surface dust over the life of the home.

Rolls of plastic foam with aluminium foil face

  • Functions only as thermal insulation
  • Performance depends on how carefully, cleanly and expertly the bricklayer spaced, sealed and kept the product taut
  • Performance depends on how much exposure the product had to the elements before the roof was put on
  • Performance drops as wall cavity temperatures rise
  • Performance drops with air drafts flowing between the wall cavity and roofspace
  • Performance drops as dust accumulates in the wall cavity
  • Performance drops with tarnishing effects of moisture


The technician consults the building plans, inspects the walls and plans a pattern of injection holes.
The 18-22mm holes (between the size of a 5 and 10 cent piece) are then drilled using a specialist European masonry cutting bit into the selected mortar joints.
Granulated ROCKWOOL stonewool is then injected in rows from bottom to top to achieve a controlled installed density.
Pumping is timed to ensure no gaps occur and small adjustments to the equipment’s pressure and flow rates are made to respond to different conditions inside the wall.
