Insulating your house is one of the most important aspects to focus on, while working on the construction plan. Presently, almost all the houses in Australia, are weatherproofed for a comfortable environment all year around. However, even after insulation, many houses do not end up achieving the right kind of temperature.
The reason behind that, can be the poor installation of the material, or incomplete insulation. A perfectly insulated house needs to be covered from all the areas that are directly connected to the outer perimeter. Including the attic, outer walls, basement or crawl area, windows and doors etc.
Here is the list of the most important parts of your house that need to be insulated, and their installation tips.
The Attic, Roofs and Ceilings
Attic or the roofs are the parts of the house that suffer the most in all weathers, with the direct sunrays, in summer, and freezing snow, in winter. The ceilings and the roofs, can make your house lose up to 45 percent of heating and cooling energy. Hence, the most important place to be insulated.
Loose-fill: Predominantly consist of small particles of cellulose and fiberglass, the loose-fill insulation install, either by being blown into the attic and cavities of finish walls, or sprayed onto these places, with water based adhesive.
Batt and Rolls: Generally, made of fiberglass, rock, wool, and cottons’ flexible fiber bind and cut into form of batt and rolls. The fiberglass insulation is one of the most popular types of batt or rolls insulation. This insulation install by placing the rolls across an unfinished attic floor, and on the spacing of wall suds.
Basements and Crawl Spaces
A proper insulation of the basement is essential, for saving money on heating/cooling as well as keeping a comfortable and warm living space. The insulation on the exterior walls of the basement minimizes the thermal bridging and heat loss through the foundation.
The other benefits of basement and crawl space insulation are:
- It protects the damp-proof coating from getting damaged by backfilling
- Protects the house from moisture intrusion
- Reduces the interior temperature swing
- Reduces the possible condensation on the surfaces and ceilings of the basement
Insulation of the exterior walls can make your house more energy efficient, and and can help save upto 20% of heating and cooling energy. Usually, walls’ insulation is done while the construction of a new house, or in case of major renovation. Either way, you can take advantage of insulating the exterior walls, according to the existing codes/norms or even going beyond those.
To insulate the exterior walls of an old house, you can use the spaces between the exterior walls and the frames of the house.
Consider foam sheathing rather than going for wood sheathing products, as they have higher R-values and offer a continuous layer of insulation.
Windows and Doors
Windows and doors, are the usual suspects that contribute towards bringing down the efficiency (temperature) of the house by letting air penetrate into the house through large gaps between their frames and the walls around them. A good caulk, foam spray, and weather strriping around the frame is sufficient, in case of minor small gaps.
Why you should Insulate your Houses in Australia
Here are some reasons that convenance you to insulate your house.
Improved Thermal Comfort
Insulation is the best cure for the winter’s freezing and summer’s burning atmosphere in the house. It helps the house to maintain a balanced thermal energy to keep you warm and comfortable, all year around, by preventing the cold/hot air to enter the house.
Less Noise, More Peace
Having a peaceful evening without any noise, from outside the house, can be little hard. Especially, when you are living in the middle of the city, it becomes essential to soundproof your house. And, in such cases, insulation can be a savior. Insulation is a great sound absorber and protect the house by reducing the sound transmission through the walls, ceiling and floors of the house.
A Budget Friendly Solution for Comfort
A well insulated house can reduce the power consumption on heating and cooling, up to 40%. Especially, the insulated ceilings can help you save up to 20% – 30% of your heating/cooling bills. By stopping the external cold/hot air, to ruin your home’s warmth and comfort, without using any extra efforts of the electric equipments.
Let’s Protect the Environment, by Not Ruining it
Why to go for CFC emitting appliances and increase the greenhouse effects on earth, when we have many natural solution to stay warm or cold, whenever we want?
Insulated houses can play a great role towards protecting the environment by helping to reduce the consumption of fossil fuels, and the pollution increasing because of them.
No More Condensation Inside the House
Condensation occurs at the roof/ceiling of the houses, when the inside temperature is below or at the dew-point of the air. Insulation increases the inside temperature above the dew-point and doesn’t let the condensation to occur.
Requirements for Insulation
Just before you start or plan the insulation for your new/old house, there are a few things that you need to consider:
- Check the Australian standards and Building Codes of Australia and ensure that the insulation meets the minimum requirements for the R-Value and the appropriate clearance are met around the electric wires and other appliances. (*R-Value is the ability to prevent heat leaking in or out of any building.)
- Installer needs to make sure that all the state and territory laws are being comply, while the process of insulation. For example, there are a few states in Australia (south Australia), where the builders need the licence to install the insulation.
