Polyester insulation is one of the safest and most sustainable insulation choices for Melbourne homes. Made from recycled plastic, it is soft to handle, free from irritants, and helps regulate indoor temperatures all year round.
For Melbourne homeowners looking for a safe and sustainable insulation option, modern recycled insulation materials offer a practical solution. Soft, non-irritating, and thermally efficient, this type of insulation suits ceilings, walls, and floors. In this guide, we explore how it works, its main advantages, and how it compares to other popular products.
What is Polyester Insulation?
This insulation is made by transforming used plastic bottles into soft, durable batts. Manufacturers create the material without added chemicals, and you can fully recycle it at the end of its life. Suitable for installation in ceilings, wall cavities, and under floors, it offers thermal and acoustic benefits.
