Check your Insulation
Your insulation may need replacing or additional thermal insulation added.
If your insulation has deteriorated it may pose a potential health risk. Fibres or airborne particles may be entering your living space.
In the past, your insulation has more than likely been disturbed or even moved by other tradespeople or previous owners. Worse still, insulation may be missing in areas due to poorly been installed.
All these problems will create hotspots in summer and heat will escape in winter, costing you money and be a potential health risk.
If your insulation was installed prior to 2012 more than likely it will be far thinner and less effective than current R4 value rating insulation standards.
In 2012, New thermal insulation standards were introduced in Australian to suit our current climate and improve the thermal energy performance and sustainability for our homes.
Before 2012 there were no mandatory standards to what R-value or efficiency rating of insulation was to be installed into your home. Most homes that took advantage of the home insulation scheme back in 2010 were installed with insulation that was less than 75mm thick with an R value 1.5. The most common type of insulation installed back then was cellulose insulation(Blow-in), Pink Batts and imported inferior insulation which has been banned and does not meet the current insulation standards.
To understand the R-value of insulation please visit:
Old Blow-in Cellulose insulation is composed of finely ground newspaper treated with fire-resistant chemicals (Borax and bonding agents) It was a common insulation material installed in most attics in older homes. Over time cellulose settles and breaks down including the chemicals, losing its fire retarding protection, rodent deterrents and its R-Value effectiveness, vast becoming a haven for rodents and spiders and a potential fire Hazard if disturbed. Water from a roof leak or condensation from Colour Bond/Corrugated tin can also degrade the insulating properties, corrode plumbing or electrical fixtures cause mildew to grow under the insulation and entering your home. In such cases, the cellulose must be removed.
We highly recommend you only install Knauf EarthWool Thermal insulation Batts.
195mm in height/thickness R value of R4.1.
Note: if your existing insulation only reaches to the top of your ceiling joists your insulation will be more than likely be less than R.2.
