Glasswool batts are lightweight, flexible insulation panels made from recycled glass and sand, designed to fit snugly between wall studs and ceiling joists. These glasswool insulation batts are widely used across Australian homes for both thermal and acoustic insulation, keeping indoor temperatures comfortable and reducing energy bills. Available in a comprehensive range of R-values to suit ceilings, walls, and underfloors, they adapt easily to different climate zones. Each batt is manufactured using up to 80% recycled content, resulting in a non-combustible, low-allergen composition that fits standard Australian framing profiles.
Glasswool Insulation - Features and Benefits
Thermal performance: Traps air in tiny pockets to resist heat flow, keeping homes cooler in summer and warmer in winter across a wide R-value range.Acoustic insulation: Absorbs and dampens environmental sound, making it highly effective for internal walls and acoustic separation between rooms.Non-combustible: Inherent material properties ensure the glass fibres will not catch fire, complying with Australian fire safety requirements.Made from recycled materials: Formulated with up to 80% recycled glass content, reducing manufacturing waste without sacrificing thermal density.Guaranteed for the life of your home: Engineered to remain structurally sound without slumping or degrading over the lifespan of the building.
Choosing the Right R-Value
The R-value measures thermal resistance; higher numbers mean better performance. Match your rating to the area:
Ceilings & Roofs: High R-values block massive radiant heat transfer.External Walls: Mid-range R-values establish an effective thermal envelope.Internal Walls: Lower R-values provide acoustic dampening and zoned climate comfort.
Check local building codes for your climate zone. For tight framing depths, high-density HP Glasswool Batts are recommended.
Our Advice with Glasswool Batts
Glasswool insulation batts are flexible panels made from glass fibres that trap microscopic air pockets to block heat transfer and lower energy bills. Pre-cut in standard 430mm and 580mm widths to fit traditional Australian framing, modern glasswool is durable, non-combustible, and low-allergen. Modern manufacturing uses fine, soft strands to minimise itchiness, posing zero irritation risk once sealed behind plasterboard. For a premium Australian-made, certified alternative you can see our Polyester Batts.
