Cable penetrations and fire safety
There are many different types of cables and cable penetrations that can pass through fire compartment walls. For example, electricity cables, optical cables, data cables, cable bundles, cable trays and ladders. Fire sealing of cable penetrations is required by building regulations.
In case of a fire, these cable services will melt and leave openings in the walls or floors, allowing the passage of smoke and fire. Cables are made of copper which will also accelerate the heat transfer through the construction which can be extremely dangerous. Therefore, all cable penetrations must be adequately fire stopped in order to comply with building regulations.
Walraven solutions
Currently we have both Acrylic and Graphite sealants in our range which are approved for fire stopping single cables up to Ø21mm and small cable bundles up to Ø50mm. Our sealants are ETA approved which means they are extensively tested to EN standards and proven to deliver fire ratings as shown in the ETA documentation which you can find on the product page.
