SuperFOIL SF19+ is a premium multi-layer reflective insulation solution engineered to deliver high thermal performance across a wide range of applications, including roofs, walls and floors. Constructed from 19 layers of low-emissivity aluminium foil and insulating wadding, SF19+ works by reducing radiant, conductive and convective heat loss within the building envelope. With an integrated vapour control layer, SuperFOIL SF19+ supports effective moisture management when used as part of a properly designed system, helping to protect the building fabric and improve overall performance. Its slim profile and flexible format make it particularly suitable for retrofit projects where space is limited, as well as new build applications requiring efficient insulation solutions. SuperFOIL SF19+ is lightweight and easy to install, reducing installation time while maintaining consistent performance. It also contributes to improved airtightness, helping to enhance energy efficiency and indoor comfort. Suitable for a variety of construction types, SF19+ is widely used in residential, commercial and social housing projects where reliable, high-performance insulation is required.
