Fabufill Polyester Insulation

Fabufill is a soft, durable polyester blanket made from recycled PET bottles, designed to improve comfort in homes without irritation or loose fibers. It’s easy to work with, holds its shape well over time, and offers a cleaner installation experience than many other insulation types. All rolls are supplied in the wider 1200 mm format, helping cover ceilings faster with fewer joins and less waste.

Fabufill is suitable for roofs, ceilings, and internal partitioning, and remains a popular option for homeowners who prefer a safe-to-handle, environmentally conscious product that doesn’t shed or release dust.

Fabufill Performance Overview

Polyester insulation offers many practical benefits, but it also performs differently from denser glasswool products. Fabufill provides safe handling and long-term durability, though polyester generally delivers:

• Soft, non-irritant material that’s comfortable to handle
• Manufactured from recycled PET bottles and fully recyclable
• Lower R-values per millimeter compared to glasswool insulation
• Lighter fiber density results in reduced acoustic absorption
• Carries a B/B1/2/H fire rating (different to non-combustible A1 fire-rated products)
• Typically priced higher per square meter than higher-performing glasswool options
• SABS approved (unlike Isotherm)

These characteristics don’t reduce its value. Instead, they place Fabufill in a category suited to homeowners who prioritize comfort during installation over maximum thermal or acoustic performance.

How Fabufill Performs in a Home

• Improves indoor temperature stability
• Helps reduce heat transfer through the ceiling
• Can assist with reducing day-to-day energy use
• Adds a level of acoustic comfort in living areas and bedrooms
• Maintains its loft and thickness when installed correctly
• Low moisture absorption and resistant to mould and mildew
• Manufactured in South Africa using recycled material

Where Fabufill Works Best

• Homes that need a non-irritant insulation option
• Properties with sensitive occupants who prefer low-dust products
• Roof spaces where handling comfort is important
• Internal drywalling and partitioning
• Installations where long-term shape retention matters
