Fire Stopping
To create a comprehensive passive fire protection system, all gaps in walls, floors and ceilings need to be fire stopped to prevent the spread of flames, smoke and toxic gases. These holes vary in size from single cables through to cable bundles, cable trays, ducts and pipes of varying shapes and sizes. Gaps can also be designed-in to accommodate structural movement within the building.
