As the leading insulation provider in Brisbane, at Insulation Guru Brisbane, we often get asked – what makes a good insulation material? The answer isn’t as simple as it might seem, as several properties contribute to an insulation material’s effectiveness. Let’s delve into these characteristics and talk about how they can benefit Brisbane homeowners, particularly those interested in Earthwool insulation.

Thermal Conductivity and R-Value

The first property to consider is thermal conductivity, which measures how well a material conducts heat. The lower the thermal conductivity, the better the material is at insulating. This property is closely related to the R-value, which indicates how well the material resists heat flow. A higher R-value means greater insulating power.

In Brisbane’s climate, where summers can be hot and winters chilly, using insulation with a high R-value can make a significant difference in your home’s comfort and energy bills. For example, Earthwool insulation’s R-value ranges from 1.5 to 7.0, providing excellent thermal resistance for Brisbane homes.

Moisture Resistance

Brisbane’s humid climate can pose challenges for insulation materials. A good insulator should have low moisture-vapour permeability and high resistance to water absorption. These properties ensure that the insulation remains effective even in humid conditions.

Earthwool insulation excels in this respect. It’s water-resistant and doesn’t absorb moisture, ensuring its thermal performance isn’t compromised over time.

Fire Resistance

Safety is paramount when it comes to choosing insulation. A good insulation material should be fire-resistant. In the unfortunate event of a fire, insulation that doesn’t easily ignite can help slow the spread of flames.

Earthwool is non-combustible and achieves a fire rating of Euroclass A1, the highest level possible. This makes it a safe choice for Brisbane homeowners.

Air Permeability

Good insulators have high air permeability, meaning they allow air to flow through their pores. Since air itself is an insulator, materials with high air permeability are often more effective at preventing heat transfer.

Earthwool’s unique manufacturing process gives it a porous structure, enhancing its insulating properties. This makes Earthwool a highly efficient insulator, ideal for Brisbane’s climate.


Finally, cost-effectiveness is a key consideration. Insulating your home is an investment, and you want to ensure you’re getting the most bang for your buck. In Brisbane, the cost to insulate a house can range from $1,500 to $6,000, depending on the size of your home and the insulation type.

Earthwool is a cost-effective insulation option, with prices typically ranging from $55 to $110 per roll, depending on the R-value. Its excellent thermal performance and durability make it a wise investment for Brisbane homeowners seeking long-term energy savings.

In conclusion, when choosing insulation materials for your Brisbane home, consider their thermal conductivity, R-value, moisture resistance, fire resistance, air permeability, and cost-effectiveness. Earthwool insulation, with its excellent thermal performance, safety features, and affordability, ticks all these boxes, making it an excellent choice for Brisbane homeowners.
