Every house has some components that are out of sight or hidden behind plaster walls. These parts are essential, although they are always forgotten when performing home improvement projects. However, they are crucial and can help you save energy costs and enhance your daily comfort during winter or summer months.  

The attic is one of the places that give less attention in a house; however, it’s one of the areas that can bring you comfort and save your heating bill. On the other hand, most homeowners in Australia consider an attic as a dark space filled with spiders, dirty, and useful when storing stuff that you don’t need or regularly use. 

However, it’s now trendy because a perfect attic that can be used as a living room.   

Benefits of Attic

Increases the value of the house

An attic can be renovated and turned into a new room that can be used as a guestroom, music studio, home theatre, and playroom for kids, or library. Thus, the more the rooms your house has, the higher the property value. 

Enhance the appeal of the property

Aussies like homes with multiple bedrooms and one way of creating that extra room is by renovating the attic and insulating it. Refurbishing your attic will create additional space, thus saving you the stress of moving to a bigger house. This will make you comfortable and will attract more buyers whenever you choose to sell it.

Insulating the Attic

The Building Code of Australia (BCA) shows that insulating the attic can help you save the heating bill. The agency states that the resistance of building material to the flow of heat, which is stated in total R-value, differs from one location to the other based on the climate zone. Thus, the homeowner should consider the following factors when planning to insulate their attic.

1. Evaluate the Condition of the Attic 

As stated, an attic is a space that should be considered and utilised in several ways. Insulation of this space is necessary, just like any other room in the house. However, a complete evaluation should be done to establish the condition of the attic. You should seek the assistance of Shepparton Insulation Services. 

Leaking roofs

These experts will identify leaking roofs or any other challenges before installing the insulation material. For instance, they will address the issue of mouldy or rotted rafters, wet and damp insulation before installing insulation

The second challenge that they will tackle is the use of undersized, sagging, or split rafters. The experts should remove them before insulating the attic to avoid problems in the future. However, some homeowners tend to ignore this procedure, for they view attic as the least essential space in the house, and they are not ready to shoulder this cost. Unfortunately, they always encounter a challenge during the snowstorm, as will be explained in the subsequent paragraphs. 

Crucial Space

More so, an attic is a crucial space that can help you save your house’s energy bill. For example, a building with an uninsulated attic experiences the following challenges. Typically, heat rises and warms the roof; this is a crucial process because it’s this heat that melts the snow on the roof after the snowstorm, thus reducing the snow load. 

On the other hand, insulating the attic does the opposite, for it inhibits the warming of the roof and allows the snow to build up and melt slowly.

Therefore, a householder that didn’t replace the undersized rafter will experience a severe problem now due to an increased load of snow that leads to roof failure. Even though Australia has relatively average temperatures characterised by plenty of sunshine across the year, the country sometimes experiences vagaries of weather, especially in areas in the Alps or Tasmania.  

Thus, it’s essential to evaluate the current conditions of the roof structure before proceeding with attic insulation to prevent occasional roof collapses that can cause inconveniences and a lot of expenses.

2. Eliminate All the Holes  

Now that you have completed the evaluation process, you can proceed to the next step and seal the cracks, holes, and gaps to prevent any transfer of air between the interior and exterior surfaces. You can use expanding foam or caulk for the sealing process will maintain the wanted temperatures and. 

One point you need to keep in mind when sealing is that a certain degree of ventilation is essential. It’s vital to recruit professionals from Shepparton Insulation services when evaluating the roof ventilation system. These experts will determine how much ventilation is needed and maintained.

3. Identifying Insulating Solution  

The next step after sealing the holes in the attic is to select the insulation materials.  Utilizing different materials are possible for this process. However, you need to consider certain factors when choosing what to use to insulate your attic.  

The R-value

It’s the thermal resistance rating of the insulating material, and it’s expressed per inch of the material. You should, therefore, select a material with a higher R-value, for it provides you with better insulation and lower energy bills.  

Further, the Building Code of Australia (BCA) provides different R-value based on climate zones. The R-values of areas with scorching and humid weather is 3-4, while regions with alpine climate have an R-value of 6. Therefore, it’s crucial to consider these figures when selecting insulating materials.   

Available Space

Various materials require different spaces to guarantee effective insulation. For instance, the fibreglass unit has an R-value of 2.9-3.8; thus, you will need different batt insulation thickness to achieve the desired R-value of where you live. At times it’s challenging to attain certain R-value due to attic conditions. 

Cost of Insulation

Some insulating materials have a higher R-factor but are expensive to install. For instance, spray foam insulation is more costly than foam insulation. On the other hand, the homeowner may consider an insulating material with a good average between the R-value and cost of the insulating material. 


It’s essential to consider the cost and space required by the insulating material to achieve optimal insulation. However, some insulating materials are flammable. Foam insulation is a material with a high score in various fire safety category. This insulating material serves as a barrier in times of fire, thus limiting the spread of flames in the house. 

Types of Attic Insulation Materials 

Homeowners select insulating materials based on factors like accessibility, R-value, flammability, eco-friendliness, and durability. The following are some of the suitable insulation materials for your attic. 

 Fiberglass Batts

It’s an attic insulation material that has reigned supreme in the insulation process. The delicate glass fibres are made of sand and recycled materials. Batts are large rolled sheets that are installed using an adhesive vapour barrier. 


It’s an insulating material made of shredded pieces of newspapers. Cellulose is a cost-effective and straightforward material. It’s treated with boric acid to keep rodents and insects away. 

Spray Foam

The insulation material is available in two types, namely the open and closed cells. The closed-cell spray foam insulator has an R-value of 7. It’s also impermeable to water, has a peak performance and durable.
