R2.5 Wall Insulation


R2.5 Wall Insulation Batts

Australian consumers are opting for higher R-values to reduce their energy bills. R2.5 wall insulation is very popular in cooler states such as Melbourne and Adelaide. Most R2.5 products offer both thermal and acoustic benefits.


Save money on electricity bills

You can save up to $478 per year on your electricity bill with wall, ceiling and floor insulation, depending on your climate zone. Insulation will save money and improve comfort for the life of the building, which is typically 50-70 years.


Quick payback time

According to ICANZ,  the cost of installing insulation pays for itself within 3-5 years through reduced energy bills. Payback times will only improve as energy costs rise. The payback time depends on several factors such as the use of the dwelling and the type of heating systems used.



R2.5 Insulation for 90mm Walls

The primary reason to install wall batts is to reduce the effect of outside temperatures inside your home. Properly installed thermal insulation will keep you warmer in winter and cooler in summer. But when choosing insulation, you may also want to consider acoustic insulation, which reduces the transfer of noise. Excessive exposure to unwanted noise can lead to stress, sleep disturbance and numerous other health complications.

Noise, Stress and Sound Insulation

The two primary reasons to consider acoustic interior wall insulation in your home are:

  1. To reduce outside noise such as barking dogs, aircraft and traffic from entering your home. This is done by installing high density thermal and acoustic insulation in the external walls of your home, creating an effective sound barrier.
  1. To reduce the transfer of noise between the rooms of your home. This is achieved by installing high density acoustic insulation in the interior walls in your home. Consider insulating between theatre rooms, studios, laundries, bedrooms and bathrooms.

Homes Insulation Costs

The cost of installing insulation (i..e hiring a professional insulation installer to do the job for you) will often be similar to the actual cost of the materials. the exception to this will be certain retro-fit jobs where, due to the difficult of access, you’ll end up paying more for the installation than for the actual materials. Factors which increase home insulation costs in retrofit jobs are things like low access, man-hole too small, ventilation duct-work in the way etc. How these obstructions will usually only affect ceiling or underfloor installations – insulating walls is usually fairly straight forward, and typically the only thing which could significantly impact on the price would be if the wall studs are unevenly spaced – – as this causes a lot of extra work for the installers.
