Improve your loft insulation with modern SuperFOIL technology that keeps your home warmer for longer—and helps lower your monthly bills.
SuperFOIL is a high-performance multifoil insulation that can be used in almost every part of your home. Its clever layered design reflects radiant heat and reduces heat transfer, helping to keep your property warmer in winter and cooler in summer.
Suitable for both homes and commercial buildings, SuperFOIL works brilliantly in roofs, walls, floors, and timber-frame structures. It’s quick to install, highly adaptable, and provides strong thermal performance across a wide range of construction types.
Whether you’re insulating a pitched or flat roof, suspended timber or solid floor, or solid or timber-frame wall, SuperFOIL helps improve energy efficiency, cut heat loss, and lower your heating bills. All products meet the necessary building regulations, and the brand is committed to sustainability by using recycled materials and reducing plastic waste in its production and packaging.
SuperFOIL comes in several options — such as SF19+ and SF40 — so you can choose the right level of performance for your project.
SuperFOIL insulation — including favourites like SF19+ and SF40 — is a great way to keep your home warmer and more energy-efficient.
