DescriptionRALIP is a high-performance thermal insulation made from recycled polyurethane foam (from refrigerators), in the form of closed-cell granules. It is blown into cavity walls through small holes (2–4 cm), filling them completely in less than a day and without the need for building work. It is 100% recycled and reusable, contains no hazardous substances or harmful fibres, and maintains constant thermal conductivity throughout its service life. It also provides thermal and acoustic insulation and damp-proofing, and is resistant to insects, rodents and mould, supporting the circular economy and energy efficiency.
