Earthwool Insulation: What You Need To Know?

Earthwool is a kind of insulation that professionals and do-it-yourself installers in Australia extensively use to enhance the thermal regulation in houses. It might be an excellent alternative for insulating a new and existing home. 

In this guide, we’ve included all you need to know regarding Earthwool, including what it is made of, why it is gaining popularity, and where it is used. So, let’s get started.

What Is Earthwool Composed Of?

Earthwool comprises millions of microscopic glass fibres that are combined with a resin joining agent and moulded into a blanket. The exception is that it is manufactured entirely of recycled glass bottles and then combined using the bio-based ECOSE technology without using any of the additional chemicals generally used in the production of glasswool.

The end product is a softer, odourless, naturally brown insulating material that is a more ecologically conscious alternative than its chemically created sibling. It also has a lower embodied energy; therefore, it has a minor environmental effect. Furthermore, earthwool insulation batts and rolls are incredibly adaptable and may be utilised in a variety of applications, including housing, industrial, and commercial.

Why Is Earthwool Gaining Popularity?

Earthwool offers many advantages that make it an excellent option for both professional and do-it-yourself installers. They are as follows:


Earthwool is created from up to 80% recycled material, and ECOSE technology emits fewer emissions during production. Installing high-quality insulation, such as Earthwool reduces your reliance on artificial heating and cooling, thereby minimising your home’s energy use. High-quality insulation that is expertly placed is a significant first step in making your house more environmentally friendly.

Outstanding Thermal Performance

Earthwool is a high-performance thermal insulation that significantly decreases heat loss and absorption. Aside from the fact that the material is a poor heat conductor, millions of microscopic air pockets enclosed in the structure of an Earthwool batt contribute to a separate flow of heat, decreasing the transmission rate. 


It is very robust, able to withstand harsh weather, and is built to endure the lifetime of your house.

Excellent Sound Absorption

Earthwool batts may have excellent acoustic qualities in addition to solid thermal properties. It is thicker and denser than standard insulation to prevent sound from passing from place to place or between inside and outside. Sound insulation may aid in creating a quiet and private interior atmosphere.

Resistant To Pest And Moisture

Earthwool is non-hygroscopic, which means it will not collect moisture from the surrounding environment. It is rot-resistant, does not support rodents, and does not promote the development of fungus, mould, or bacteria. Because of these characteristics, earthwool insulation is a long-lasting and healthier option for your house.

Simple To Use

Earthwool Insulation batts are simple to cut and manage, making them an excellent option for expert insulation and do-it-yourself installers. Earthwool wall batts are pre-cut to suit Australian homes’ most typical wall gaps.

Effective Packaging

Because earthwool is very foldable, you may receive more metres squared from a single box. This makes shipping the products more manageable and may help save money on storage and transportation expenses.

Gentle To Touch

Because of the lengthier strands of insulating material, earthwool is pleasant to the touch and has a really low itch component. The longer the strands, the fewer endings of the strands that cause the irritation.

Safe to Use

Earthwool Insulation is made entirely of sustainable bio-based resources and is free of toxic petroleum-based substances and artificial colours. It is suitable for use by do-it-yourself installers.

Is Earthwool Water Absorbent?

Earthwool is non-hygroscopic, implying it will not accumulate moisture from the surrounding environment. They are also resistant to fungal, mould, and bacterial development. If you have a big leak or your roof sustains storm damage, the efficacy of your insulation may be compromised — this is true for all forms of earthwool insulation. Moreover, water-damaged insulation may have to be changed when the leak is addressed.

What Is The Use Of Earthwool?

Earthwool has thermal and noise insulation solutions that may be utilised throughout the house to increase energy efficiency and minimise sound transmission.

Thermal Insulation

Thermal insulation lowers heat movement into and out of your house, making it simpler to maintain a pleasant temperature in your rooms while reducing your energy expenditures. Earthwool thermal insulation may be utilised in multi-story homes’ ceilings, walls, beneath floors, and between levels.

Noise Insulation

Noise insulation minimises sound transmission between rooms and may lessen the amount of noise entering your house. They are most often used in external walls, internal walls, and between floors, although they may also be used on the roof and underfloor if needed. Earthwool acoustic wall batts, like thermal wall batts, fit in most standard wall frame sizes.

When constructing or remodelling your home, one of the most critical elements to consider is earthwool insulation. Suppose you want to stay warm in colder areas and cool in hot ones. There are several kinds of insulation to choose from, and you must select the correct one for your property.
