Filling the gap in your comfort
The benefits of incorporating Energy Saver Cavity Wall Insulation to your housing designs are:
1. It will not disrupt your brick layers
They can do what they do best, lay bricks and not have to change their methodology during construction and worry about ensuring correct installation methods.
2. Long term proven Performance
This method of Wall Installation is not new, it was developed and perfected in the United Kingdom and has provided over twenty five years of proven service after being installed into an estimated three million homes.
3. Fire Safe Insulation
Rockwool Insulation is classified as non combustible, this ensures that it will not burn, melt, and cause hazardous fumes when exposed to an ignition source. i.e. when gas and water pipes are connected.
4. Health Safe Insulation
Rockwool has had over 30 years of exhaustive research. In October 2001, an international expert panel reviewed by the International Agency for Research of Cancer (IARC) evaluated the latest scientific and medical evidence on Rockwool insulation. As a result Rockwool was reclassified from a Category 2B to a Category 3 “not classified as carcinogenic to humans”. The major ingredient is volcanic rock.
5. Improved Acoustical Performance
When used in conjunction with Resilient Wall Ties and Energy Saver Cavity Wall Insulation can be expect to provide an Rw rating of 56-58.
6. Proven Moisture Resistance
Energy Saver Cavity Wall Insulation will not transmit water to the inner leaf, nor will it transmit moisture by capillary action across the cavity or from below the damp-proof course level.
7. Recycled Product
Energy Saver Cavity Wall Insulation is made from 100% recycled Rockwool. The recycling process occurs at our manufacturing facility in Jandakot.
8. Guaranteed Performance
When supplied and installed Energy Saver Cavity Wall Insulation has a performance guarantee to ensure the insulation performs as stated.
Energy Smart Housing Design
By incorporating Energy Saver Cavity Wall Insulation during the construction process, your home could achieve a minimum of a Five Star energy rating. Thus:
- Requires less energy to heat or cool their home,
- Reduced Greenhouse emission footprint,
- Is future proofed against housing energy requirements upgrades,
- Has non-combustible, fire safe, insulation installed, AS 1530 Part 1-1993,
- Offers a quieter living environment, and
- Allows increased design flexibility.
It is important to understand that Thermal Mass does not equal Thermal Resistance
By isolating the internal thermal mass you are able to maintain a more even steady state internal temperature, during summer and winter extremes, without the need to rely on energy using appliances to maintain a comfortable living temperature.
Have you ever wondered why Perth’s houses are seemly uncomfortable during long hot spells during summer? The Sustainable Energy Development Office in Perth explains the following about Double brick walls.
”Double brick walls heat up slowly and stay warm for long periods. This is an advantage during short periods of hot weather, but can make your home uncomfortable over extended hot spells. Insulating double brick walls will add to initial costs, but will help to prevent heat transfer to the interior of the home during summer and help to retain heat during winter."

The Good Residential Guide says that you can:
“... save up to an additional 15 percent on heating and cooling energy with wall insulation.”
Recently Origin Energy in its submission to the Sustainable Cities enquiry drew to the attention of the committee the savings that can be made with energy efficient homes:
What is currently missing is a comprehensive appreciation of the value of ecoefficiency. For example, a home that uses 50% less energy than an average house will save its occupants around $800p.a. Assuming a mortgage rate of 7% and inflation of 2.5%, this would mean that the buyer could afford to spend $12,000 on the house and be no worse off (1).
Complete Supply and Installation Package.
Energy Saver Cavity Wall Insulation is easily installed into the cavity after the walls are constructed, before the roof is applied. Any wiring, plumbing that is required in the cavity can be completed before the insulation is installed.
Insulation Knowledge Centre.
AIS Home Insulation has a number of key personnel that have been involved in the insulation industry for over 20 years. AIS Home Insulation is a part of Australasian Insulation Supplies, for the past 10 years the Australian agent for the worlds biggest stone wool manufacturer, Rockwool International, and can draw on these immense resources of the Group.
Importantly we view AIS Home Insulation as an Insulation Knowledge Centre, where you are able to clarify insulation questions and issues that will affect your clients’ residence. We pride ourselves in providing accurate and practical information.
