AF BAGS are intumescent and ablative fireproof pillows certified under EN 1366-3 for sealing up to EI 240 of cable tray penetrations.
AF BAGS are recommended when frequent systems maintenance or modification is required. They can be easily removed and re-positioned once the work has been carried out. AF BAGS consist of a non-combustible glass fibre casing, treated with a special polyurethane product containing intumescent granular material, thermal insulating aggregates and products which gradually release water. The AF BAGS expand as the temperature rises (over 180°C).
