When cable trays pass through walls or floors, seal openings using fire-rated penetration sealing materials. Do not modify or damage the tray coating or structure during use. Seal cable penetrations with our modular firestop solutions, designed to create water-, smoke- and gas-tight barriers in. One of the most commonly recurring non-compliances seen during an annual assessment is the absence, or inadequate sealing, of cable penetrations passing through the fabric of a building. Whether it's a cable tray running through a wall or pipework penetrating a ceiling, any breach in a fire-rated barrier can allow fire and smoke to spread rapidly. Cables, cable bundles, conduits, bundles of conduits, empty pipes, cable trays and cable ladders may also pass through penetration seals in walls and floors and should be taken into consideration during all phases of design and application.
