Polyester Performance Notes
40mm Fabufill is selected primarily for its soft handling and lightweight structure, though polyester insulation naturally differs from denser glasswool products. Homeowners should expect:
- Lower thermal performance per millimeter
- Lighter fiber density
- Softer acoustic improvement
- A different fire classification
- Slightly higher cost due to PET-based manufacturing
These characteristics are normal for polyester insulation and do not reduce the suitability of 40mm Fabufill where clean, irritation-free installation is the priority.
Ideal Applications
- Ceilings requiring a very thin insulation layer
- Roof spaces with limited clearance
- Properties needing a clean, non-itch product
- Internal partitions and lightweight structures
- Installations benefiting from wide 1200mm roll coverage
Installation Notes
- Easily cut or torn with scissors or shears
- Can be laid on ceiling boards or suspended between trusses
- Space rolls with a 50mm gap around downlights and heat sources
- Store rolls horizontally, under cover, and keep dry
- Butt or lap ends carefully to maintain continuous coverage
- Fit snugly between trusses for even performance
Why Choose 40mm Fabufill
40mm Fabufill offers a lightweight, easy-to-handle insulation solution for homes needing a thin polyester layer without irritation, dust, or fibrous material. Its clean installation, stable loft retention, and wide roll format make it a practical choice for light-duty ceiling and partition applications.
