What it does Reflective radiant barrier made from aluminium foil with soft air bubbles inside, up to 5 mm thick. In summer it blocks solar heat from entering living spaces; in winter it reflects heat radiated from radiators back into the room to help maintain warmth. Key benefits (why you need it) Lower running costs: reduces the load on heating and cooling systems by improving thermal performance of walls, floors and ceilings. Year‑round comfort: helps keep rooms cooler in hot months and warmer in cold months. Noise reduction: the air‑bubble core provides added sound dampening in addition to thermal insulation. Easy and fast installation: self‑adhesive backing eliminates the need for additional glue. Important attributes Material: aluminium foil radiant barrier with soft air bubbles. Thickness: up to 5 mm. Installation: self‑adhesive — peel and stick; also simple to cut to the shape and size you need. Compatibility: suitable for lofts, roofs, storage rooms, walls, floors, conservatories, behind radiators, caravans and similar spaces. How it solves problems Stops direct solar heat gain through roofs and conservatories to reduce indoor overheating. Reflects heat from radiators and heating systems back into rooms to reduce heat loss through walls and floors. Fits tight spaces (behind radiators, under floors, inside loft voids) where thicker bulk insulation is impractical. Typical applications (practical scenarios) Behind a radiator: stick the foil directly to the wall behind the radiator to reflect heat back into the room and improve heating efficiency. Loft or roof lining: apply under rafters or across loft floors to reduce heat transfer through the roof and limit summer heat gain. Caravan or floor refurbishment: use under floorboards or internal panels to improve thermal comfort and reduce noise inside mobile homes or storage rooms. Installation tips Measure and cut with a utility knife or scissors to match the area. Ensure the surface is dry and clean before applying for adhesion. Overlap edges where possible to reduce thermal bridging. This product provides a thin, reflective insulation layer that improves thermal efficiency and reduces noise without the need for adhesive purchases or complex fitting.
