Service penetration seals are passive fire protection systems designed to maintain the fire resistance of building element or section - wall or floor - where services such as cables, cable trays, pipes or ventilation ducts pass through them. Where cables pass through shafts, walls, slabs, or enter electrical panels or cabinets, openings shall be tightly sealed with firestopping materials in accordance with. Cable penetration seal up to EI 120 for rigid walls, rigid floors and flexible walls. Effectively fill spaces caused by pipes and cables traveling between walls with 3M's through penetration products. NOFIRNO provides the highest fire ratings, the shortest installation times, and a long-term, maintenance free service life.
