In this Bitesize CPD we will be looking at the use of expanding fire foam used to fill holes in walls or ceilings.
Invariably incorrectly installed it is one of the more common defects picked up by FCM’s, Clerks of Works during their site inspections.
Increasingly expanding (pink) fire foam is being used to fill holes and penetrations. Do you know whether it is really a fire barrier?
In the photograph above it is being used to fill a penetration through a fire wall. There are no fire collars on the plastic pipes and the foam will not provide the required 1 hour of fire protection.
The openings around metal pipes and cables, but even blank seals can allow a fire to penetrate. For this reason, these openings must be sealed against fire. For cable trays and pipes, Soudal offers fire-resistant solutions tested in accordance with European standards (EN 1366-3).
These installation instructions are drawn up to guide the installer through the correct process of sealing openings against fire. The correct execution of these instructions ensures that the products are installed in accordance with the test certificates. Only then is it possible to guarantee the fire-resistant capacity of the products in accordance with EN 1366-3. Always ask for the test certificates before starting any work.
