AF SLEEVES

AF SLEEVE is an intumescent sleeve certified to the EN 1366-3 standard for sealing penetrations of combustible pipes, cable bundles and insulated metal pipes – whether with combustible or non-combustible insulation – in walls and floors.‎ Composed of a material with high thermal expansion properties, AF SLEEVE seals through-penetrations by blocking the gap left by the collapse of the combustible pipe or the melting of the insulation.‎ The product’s reduced thickness makes it possible to apply it around the pipe directly within the support structure.‎ Further info from manufacturer on AF SLEEVES AF SYSTEMS
