40mm Fabufill Insulation
40mm Fabufill Insulation is the slimmest option in the polyester ceiling insulation range, designed exclusively for topping up existing insulation layers or for use in very tight ceiling spaces. Manufactured from recycled PET plastic bottles, it provides a safe, eco-friendly, and installer-friendly solution. The product is non-irritant, dust-free, and non-allergenic, making it suitable for both DIY homeowners and professional installers.
While it delivers the lowest thermal resistance in the range, the 40mm roll still helps improve energy efficiency, reduce unwanted heat transfer, and create a more stable indoor climate when used as a supplementary layer.
