Effective Home Insulation: Choosing Fibreglass, Glasswool & Vapour Barriers

Insulating your home is one of the smartest ways to boost comfort, reduce energy costs and protect your living space from moisture damage. At Better Batt Insulation, we offer high-quality fibreglass insulation, glasswool insulation and vapour barrier solutions tailored to the demands of Australian homes.

These materials form the core of an energy-efficient and weather-resistant building envelope. Whether insulating a ceiling, wall, underfloor or roof space, our expert team will help you choose the right combination to suit your needs, budget and Melbourne's ever-changing climate.

Improving Energy Efficiency with Fibreglass and Glasswool

If you're looking for proven performance and long-term energy savings, fibreglass and glasswool insulation are among the most effective materials. Both are made from fine strands of recycled glass spun into a wool-like texture, making them lightweight, flexible and highly efficient at trapping heat and slowing its transfer through your home's structure.

At Better Batt Insulation, we supply a wide range of glass wool batts and rolls from trusted brands like Bradford and Earthwool, ideal for use in:

  • Ceilings – Preventing heat rising and escaping in winter
  • Walls – Reducing both temperature fluctuations and noise
  • Underfloors – Blocking cold air and draughts from below
  • Roofs – Essential for regulating indoor temperature year-round

Upgrading your home with fibreglass or glasswool insulation improves thermal resistance (R-value), reduces reliance on heating and cooling systems, and significantly reduces electricity bills. Additionally, these materials provide great acoustic insulation, making your living spaces quieter and more peaceful.

For environmentally conscious homeowners, our glass wool products are low in embodied energy and made using recycled materials, making them a sustainable choice without compromising performance.

Preventing Moisture Damage: The Role of Vapour Barriers

In addition to insulation, protecting your home from moisture is essential, especially in Melbourne's varied climate, where humidity, rain and temperature changes are common. A vapour barrier is a protective layer that prevents moisture from entering your wall or ceiling cavities and damaging insulation or timber framing.

Warm indoor air can penetrate insulation layers and condense when it hits cooler surfaces without a barrier. This can lead to:

  • Mould and mildew growth
  • Reduced insulation performance
  • Timber rot and internal wall damage
  • Increased health risks for asthma and allergy sufferers

Installing a vapour barrier alongside fibreglass or glasswool insulation helps create a sealed envelope that maintains thermal performance while keeping your building dry and healthy. Our team can advise you on whether your project requires a vapour barrier and how to install it correctly for maximum effectiveness.

Whether you're a homeowner, builder or architect, Better Batt Insulation offers complete insulation systems that combine glass wool and vapour barrier technology to meet modern building standards and ensure long-term protection.

Frequently Asked Questions

Fibreglass insulation and glasswool insulation are essentially the same material. Both are made from spun glass fibres and offer excellent thermal and acoustic properties. The term "glass wool" is commonly used in Australia, while "fibreglass" is more popular in the US, but the products are functionally similar.

Yes, modern fibreglass insulation is safe when installed correctly. It's non-combustible, resistant to mould and pests and made from recycled materials. However, wearing protective gear during handling is always advisable, as loose fibres can cause minor irritation during installation.

A vapour barrier prevents moisture from passing through walls, ceilings or floors and condensing inside insulation or structural materials. It's especially important in humid environments or when using glasswool insulation, as it helps preserve thermal performance and prevents mould and rots in building materials.

Many DIY homeowners install glass wool batts or fibreglass insulation, especially in roof and wall cavities. However, it's important to follow safety and installation guidelines to avoid gaps or compression and to install a vapour barrier if needed. For optimal results, professional installation is recommended.

In most Australian homes, the vapour barrier is installed on the warm side of the wall, typically behind the plasterboard, facing the living space. However, placement can vary depending on your climate zone and construction type. Our team can help you determine the right setup for your Melbourne property.
