For approximately 40 years, unprotected or improperly protected penetrations have presented a subject of much concern to the fire-protection community. The arriving firefighters discovered several fires had broken out in five remote locations, filling many different areas of the building with smoke.

A building design can look well protected from fire on paper, but even with the best will in the world there will be unexpected changes on site — particularly where service lines are concerned. Commonly installed once the fire rated walls, floors and ceilings are in situ, service lines create voids which must be remediated from a fire protection perspective to ensure that the building will perform as intended. Even the smallest of gaps created for services will compromise fire protection performance and pose a risk of fire spreading. ROCKWOOL has developed a range of stone wool solutions to reinstate the fire performance of compartment walls and floors after the installation of services.

What are membrane penetration firestop systems and how has the penetration firestop standard evolved to evaluate them? The changes include a new section for definitions relating to the various types of membrane-penetrations, a description of the test setup for membrane-penetrations, and the conditions of acceptance for membrane-penetrations. For example, when a firestop system protecting a plumbing pipe penetrates the gypsum membrane on one side of a fire-resistance-rated gypsum wall, this revised standard would be used to evaluate that firestop system.
