In Melbourne, as in many other cities throughout the world, residents must deal with unpredictable and often severe weather. In our metropolis, it is not uncommon to experience four distinct climate zones within a single day. Summers are getting warmer and longer into the winter season, while winters are getting warmer and longer into the summer season.
How do you keep your home or business at a suitable temperature while the weather outside is always changing? Air conditioners and heaters are a convenient way to quickly alter the temperature and humidity levels inside a building, but they do not come cheap. Having these gadgets on all day can soon add up in electricity costs, and the artificial air they produce isn't exactly great for your health.
Insulation is the finest and most natural way to achieve a comfortable indoor atmosphere. When you insulate your home or business, you provide the strongest possible defence against weather extremes and reap a slew of other benefits as well. But, the issue remains: which type of insulation is ideal for you? To that end, we have compiled a quick guide to assist you better understand which type of insulation will work best for your needs.
What Are the Benefits of Insulation?
There are some positive factors to consider when picking insulation. Increased thermal efficiency is the most noticeable advantage of having good insulation. The ability of your house to sustain a comfortable temperature inside is what thermal efficiency evaluates. Insulation is a necessary component to making any room more productive. Insulation of sufficient quality is your best bet for keeping your desired indoor temperature all year long.
The use of climate control appliances like air conditioners and heaters will be drastically reduced after proper insulation has been installed. Naturally, this will reduce the amount of money you have to spend on utilities, allowing you to keep more of your hard-earned cash. The cost of installing insulation is quickly recovered through these cost-cutting measures.
The contribution to the environment is a natural byproduct of reducing appliance use, but it's still an amazing perk. You can help make the world a better place by minimising your carbon footprint and cutting back on the amount of natural resources you use by using less of these appliances.
It's been shown that insulating a house during construction makes it go up in value and also reduces the time it takes to complete the house. Because insulation is installed before bricks or classes are laid, construction inside the building can continue without interruption.
Insulation also helps to reduce noise in your building, which is a major perk. Because this additional insulating material acts as a barrier between the interior and the outside, it will make your home quieter.
For a more localised understanding of the benefits of insulation, consider that in Victoria, Australia, heating and cooling a home can consume as much as fifty percent of a family's monthly energy expenditure. As was previously said, insulation is a great way to drastically reduce this. Without insulation, a home can lose as much as 35 percent of its heat in the winter and gain about the same amount of heat in the summer. In the winter, heat loss from the windows is between 10-20%, while heat gain might approach 35%. Up to 25% of a home's heat is gained or lost through the walls, while up to 20% is lost through the floors.
The R-Values You Need to Know
Understanding R values is necessary before discussing the various insulation options. The R-value is a standard for evaluating the effectiveness of insulation in blocking heat transfer. The R-value of insulation, which ranges from 1.5 to 7, indicates how well it will insulate a building. There are three types of R values that are relevant to this discussion:
- 'Up' R-Value
- The effectiveness of the insulation is evaluated by how much heat is retained within the structure. In the winter, when heat is expensive, it is ideal to have a high up R-value, hence the term "winter R-value" is sometimes used.
- 'Down' R-Value
- A building's insulation is evaluated based on how well it prevents heat from entering the structure. For the same reason that a high down R-value is preferred in the summer to keep your home cool by letting the heat outside, this is also known as the summer R-value.
- Total R-Value
- Add the positive and negative R-values together to get the overall R-value. This is what is often meant when the word "R-value" is used.
It's not always best to go with the highest possible R-value when deciding what's best for your home. This is due to the fact that varying degrees of heat resistance are required for homes of various architectural styles and climates. One house may need insulation with an R-value of 7, whereas another of equal size and construction could get by with an R-value of 4. Asking for an expert's opinion after an inspection of your home is the greatest way to figure out what needs to be done.
Different Types of Insulation
Insulation comes in a few main varieties that are widely employed in modern Australia. Insulation types include reflective, bulk, and (less effectively) spray foam.
Reflective Insulation
Insulation that reflects light back into a room is both very effective and inexpensive, making it a popular choice for modern Australian homes. Insulation that reflects radiant heat, such as that made of aluminium foil, keeps the heat outside of a building. In warmer climates, installing reflective insulation in the walls, roof/ceiling region, and under the floor is the most effective method of energy conservation (though it is beneficial in cooler climates, too).
Bulk Insulation
Bulk insulation, the most common kind of insulation sold by insulation experts and hardware stores, works by trapping air inside millions of small bubbles to block heat passage into your property. Rolls, boards, and batts made from various materials are all on offer polyster, natural wool, cellulose fibre, and glass wool make up the bulk of its composition. Insulation in both its bulk and reflecting forms can be installed for maximum efficiency.
Spray Insulation
Spray foam insulation is an innovative new type of insulation that provides significant benefits over traditional insulation methods. To install this type of insulation, you spray a solution into the ground, walls, or ceiling, which causes a bubble to rise and form a thick layer. The R-value is greater than that of conventional insulation, and its resistance to moisture means it won't sag as rapidly as bulk insulation would. Spray insulation may not be the best choice if you're trying to save money, as it's more expensive and more combustible than conventional insulation. Spray insulation is useful in inaccessible areas that are difficult to insulate using more conventional methods. There is a hybrid that combines spray insulation with reflective and batts.
Installing Wall Insulation
It's important to know what kind of walls you have before deciding how to insulate them. Bulk insulation is the most effective form of insulation. Millions of small pockets packed with air make up bulk insulation; other gases include:
- Materials that are inefficient heat conductors.
- There are more empty spaces.
- Better insulation means better temperature control.
Bulk insulation, so named because of its weight, is available in batts/blanket forms, board, and spray. If insulating an attic, for example, is something you want to do on your own, you might want to use blanket and board insulation.
It's not possible to utilise typical insulation techniques on some walls, including double brick walls, because special tools are required to access the interior. The walls should be insulated using spray foam. First, holes are drilled at regular intervals in the wall, and then the insulation is sprayed into the holes. We then use mortar to fill in the spaces.
Keep in mind that hiring a professional to install the insulation will increase the expense of this option. On the bright side, a professional can help you determine which insulation is ideal for your home, and they can also ensure that it is properly installed.
Bulk insulation is not recommended in the hottest parts of Australia; reflecting insulation is (sometimes called radiant barriers). In order to keep your home from getting too hot, this insulation is great because it reflects the sun's rays. Also, it helps keep your home cooler on hot days because less heat is trapped inside.
FAQs About Exterior Insulation
Insulation is important because it helps reduce energy costs by keeping buildings cooler in the summer and warmer in the winter. It also helps improve comfort levels by reducing drafts and noise pollution.
Common types of insulation used for outside use include foam board, mineral wool, cellulose, and spray foam insulation.
Outside insulation does not require much maintenance but should be inspected periodically to ensure that it is still in good condition and not damaged by weather or other factors. Any damage or wear should be repaired promptly to prevent further damage.
While it is possible to install outside insulation as a DIY project, it is recommended to hire a professional contractor who has experience in insulation installation to ensure proper installation and safety precautions.
The benefits of outside insulation include improved energy efficiency, reduced energy bills, improved indoor comfort, reduced noise transmission, and increased resistance to moisture damage.

Insulate Your Home Properly—Do You Need Bulk or Reflective Insulation?
Bulk insulation and reflective insulation are the two most common types of roof insulation. The air is trapped within the structure of the bulk insulation, which contains millions of small air pockets. Without the air spaces that provide insulation, bulk insulation is rendered ineffective. The insulation stops heat from transferring via the air between neighbouring objects.
Nevertheless, reflective insulation is more effective at reducing heat loss by radiation. A foil layer is typically supported by a paper or plastic layer. In order for the reflective foil to do its job, it must be kept clean and used with the shiny side facing down. Recently, bulk and reflective insulation have been integrated into roof insulation designs to maximise efficiency and effectiveness.
Which Roofing Insulation Product Is the Most Effective?
Several kinds of insulation, such as bulk insulation and reflective insulation, are used for roofs. Glass wool and polyester are the most popular choices for insulation in large quantities. Glass wool and polyester insulation products from Pricewise Insulation are available in a range of thicknesses and R-values to meet the thermal performance needs of a wide range of home designs.
Glasswool Bulk Insulation
Glasswool insulation is the most widely used type of insulation since it is inexpensive and easy to install. Although glass wool has a bad rep for being irritating and unpleasant to work with, new technologies have made it much more tolerable. Nowadays, itchy-free or low-itch products are advertised for a wide variety of glass wool insulation options.
Polyester Bulk Insulation
Insulation made from polyester is created from used beverage containers and other PET plastics. There are no chemical binders used in the manufacturing of heat-bonded polyester insulation. This is what makes polyester so sturdy, adaptable, and allergy-free.
Foil Reflective Insulation
Foil insulation is effective against solar radiation because of its reflecting surface, which acts as a radiant barrier. If you want to take use of foil insulation's full insulating potential, you need to make sure it's fitted properly. Reflective foil insulation's R-Value is conditional on factors like its placement and the local weather.
Should I Get Insulation Rolls Or Batts For My Roof?
In a practical sense, it's up to you to decide. Both types of bulk insulation have the same insulating power. The installation procedure is the primary distinction. Instead of having to cut the insulation into sections to fit between the ceiling joists, you can just "roll" it out. This is especially helpful in those (very uncommon!) cases where there is a huge, unobstructed area of ceiling available for work.
On the other hand, if your ceiling is low and there are many obstructions in the way, insulation batts may be a better choice. Batts are convenient since they can be trimmed to size before installation.
Are You Adding Insulation to an Existing Ceiling or Constructing a New Structure?
Ceiling insulation can be installed in both new and existing homes by insulation contractors. The R-Value can be increased by installing new insulation on top of existing insulation if necessary. However, if the old insulation is broken, mouldy or infected, it should be thoroughly removed before the new insulation is installed.
Pitched Roof With A Flat Ceiling
Insulation may be installed from within the crawl space of a pitched roof with a flat ceiling. Installing sarking or foil batts beneath the roof and insulation batts in between the ceiling joists can aid with radiant heat loss.
Roofs With No Crawl Space
To insulate a roof without a crawl area, for instance, you should lay insulation batts on the plaster before lifting the metal roof. Finally, to keep radiant heat out of the house, lay down silver-side-up sarking or Kingspan Air-Cell Insulation.
If you have any questions regarding which type of roof insulation will be ideal for your particular project, don't hesitate to give our insulation experts a call.
What Is a Good R-Value for Roof Insulation?
As a result, you may be wondering, "What is the most efficient roof insulation?" The insulation product's R-Value is the most crucial thing to think about. The R-Value expresses how well it insulates against heat transfer in either direction. The greater the R-Value of an insulation product, the more efficient it is and the less money you can expect to spend on heating and cooling.
More than a third of a home's annual energy costs can be attributed to heat gain or loss through the roof. To ensure your home maintains a comfortable temperature all year, it is crucial to select the appropriate R-Value for the insulation in your roof. Depending on where you live, there are different minimum R-Values that must be installed, as outlined in the Building Code of Australia.
What Is the Best R Rating for Ceiling Insulation?
The ceiling should have an R-value of R5.0 or R6.0 at a minimum for use in Melbourne, Sydney, and Adelaide. We advise at least R4.0 for Perth and Brisbane, which are located in warmer climates.
What Type of Insulation Is the Most Energy-Efficient?
More insulation and efficiency result from a higher R-Value. Upgrading to the greatest R-Value you can afford will result in improved temperature regulation and energy efficiency in your home and is highly recommended if at all possible.
