Home Insulation

Household Energy Requirements
Statistics shows that a private home in a temperate climate generally needs around 20,000 kilowatt-hours per year (20000 kW•h/year) to fulfill its energy needs.

Similarly a private home in a subtropical climate generally needs around 8000 kW•h/a (1 kW) to fulfill in its energy needs.

Australian Energy Sources

The majority of Australia’s electricity is produced using coal, accounting for 84 per cent of all fuels consumed by generators (in energy content terms) in 2006-07.  This is because coal is a relatively low cost energy source in Australia. It also refl ects the abundance of coal reserves along the eastern seaboard, where the majority of electricity is generated and consumed.

Australian Household Energy Consumption Patterns
Here below are the Australian household energy usage patterns and shows the trends in 2020. This clearly shows that about 59-64% of the household energy is used in heating/cooling space or water heating.

Space heating / cooling apparatus that work on electricity  or other energy sources (eg gas, wood from gas stoves, gas heaters,  wood burners, ...) are the most important user of household energy. This is also contributing a lot to the environment as carbon emissions.

Looking into this scenario, Australian government has realized this issue and recently announce roof insulation plan throughout Australia. thus not included. The basic objective of this scheme is to utilize energy in a better way by maximizing its efficiency by reducing energy losses through the buildings.

You can get your house insulated without paying any amount for the material or labour charges. In addition with that you will enjoy 30-45 savings in energy sued in heating and cooling of  your premises and hence save huge amount sin your electricty or other energy bills. Insulating every home properly cuts fuel bills in the average home by up to half. Insulating every home properly also cuts fuel bills in the average home by up to half. This helps everyone at a time of rising energy prices, but especially people on low incomes in older, more run-down housing who - even though they can ill afford it - spend more of their income than the better off, just to keep warm.

Trends in Energy by Major End Use
This helps everyone at a time of rising energy prices, but especially people on low incomes in older, more run-down housing who - even though they can ill afford it - spend more of their income than the better off, just to keep warm. This will prove to be a good gift from the government at the time of recession. With the current move by the Australian government, this scheme will not only help face the challenge of climate change but also reduce fuel bills in these economically difficult times.

Not So Greens --. The house warming party
Carbon emissions from homes were a staggering 27% of total emissions in the Australia in 2007 and this programme alone can cut that by 25%. Insulating every home properly also cuts fuel bills in the average home by up to half. This helps everyone at a time of rising energy prices, but especially people on low incomes in older, more run-down housing who - even though they can ill afford it - spend more of their income than the better off, just to keep warm.

Why Insulate Your House?
Heating and cooling account for 50 to 68% of the energy used in the average Australian home. Inadequate insulation and air leakage are leading causes of energy waste in most homes. Insulation:  

  • Saves money and our nation's limited energy resources 
  • Makes your house more comfortable by helping to maintain a uniform temperature throughout the house, and
  • Makes walls, ceilings, and floors warmer in the winter and cooler in the summer.

The amount of energy you conserve will depend on several factors: your local climate; the size, shape, and construction of your house; the living habits of your family; the type and efficiency of the heating and cooling systems; and the fuel you use. As the Australian  government is paying for the whole initial cost of insulation, the energy conserved is your money saved - and saving energy will be even more important as utility rates go up.

This fact sheet will help you to understand how insulation works, what different types of insulation are available, and how much insulation makes sense for your climate. There are many other things you can do to conserve energy in your home as well. The Department of Energy offers many web sites to help you save energy by sealing air leaks, selecting more energy-efficient appliances, etc.

How Insulation Works
Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements - wherever there is a difference in temperature.  

During the summer, heat moves from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat.
Batts, blankets, loose fill, and low-density foams all work by limiting air movement. (These products may be more familiarly called glass, fiberglass, cellulose, wool, polyester and expanded polystyrene.) The still air is an effective insulator because it eliminates convection and has low conduction. Some foams, such as polyisocyanurate, polyurethane, and extruded polystyrene, are filled with special gases that provide additional resistance to heat flow. Details of some of the available materials is given as below


Glasswool Batts / Fibreglass Batts
We have glasswool batts from various source in pink, green and standard yellow colour for ceiling and walls. It is lightweight, flexible and resilient glasswool insulation batts, specially designed for thermal insulation of ceilings and cavity walls in both domestic and commercial buildings.


They have the added benefit of being an effective sound absorber and so contribute to both the thermal and acoustic comfort of building occupants.

Polyester Batts / Plyester-Wool Mix/ Wool
Our  thermal Batts are lightweight products manufactured from thermally bonded polyester fibre, with 80% recycled fibres. We have three materials for insulation batts i.e., Polyester, Polyester/Wool mix and wool. These materials are non-toxic and user friendly requiring no specific protective clothing. They will not corrode or deteriorate over time. These batts are hydrophobic and naturally repels water so that the product remains largely unaffected by accidental exposure to moisture.

Reflective insulation works by reducing the amount of energy that travels in the form of radiation. Some forms of reflective insulation also divide a space up into small regions to reduce air movement, or convection, but not to the same extent as batts, blankets, loose-fill, and foam.
Note: There have been some accidents of fire as these reflective insulations were laid down by some un-professional installers which with electric wire sparks caused fires in many houses. So you should avoid laying this reflective insulation on or near electric wiring.

Insulation of your home is an excellent way to make it more energy efficient. It reduces the rate of heat loss/gain in your home. This means it stays warmer in winter and cooler in summer making it much more comfortable and reduces the need for heating and cooling that contribute to the greenhouse effect.

When employing contractors to carry our works in your home, ensure he is using the right material with care.

Loft Insulation
Heat rises, so 25% of heat can be lost through the roof area. By insulating the roof, much more heat is retained within the property, which can have significant reductions on your heating bill. Savings of up to $200 can be achieved per year.

To see climate of your area and thickness of the suitable insulation required, (see climate maps at

A well Insulated home provides a warmer home in the winter and a cooler home in the summer.  By increasing the standard of your insulation to roof and walls you can reduce your heat loss by up to 65%.
