DescriptionPortuguese producer of expanded cork agglomerate (ICB), with a factory in the municipality of Abrantes. ICB is obtained by expanding cork granulate with steam at high temperature: the cork's own resins bind the block, with no added adhesives. The result is a natural, breathable and very durable insulation, suitable for façade, roof and floor, even as an exposed finish. Sofalca is one of the leading producers of this material in the peninsula.
