Mike Conneely of Greenside Design Build walks through the fire-stopping work required before rough inspections, showing how builders seal openings and penetrations to limit the movement of fire between floors and wall cavities. He covers common applications around framing, ceilings, electrical conduit, plumbing, exterior boxes, and other penetrations, while also noting the air-sealing benefits of the work. Mike explains how fire stopping differs from a residential sprinkler system and describes coordinating window insulation with the same stage of construction. The process continues throughout the house as the team prepares for rough inspections and subsequent insulation.
