Wall bushing: the key component for maintaining safety in fire compartmentation

In industrial facilities or buildings with a fire risk, every detail matters to ensure safety. In this regard, when it comes to fire compartmentation, wall bushings become an essential element to comply with fire resistance certifications.

What is fire compartmentation?
Fire compartmentation is the division of a building into fire sectors using fire-resistant construction elements (such as walls, floors, or fire doors). Its purpose is to limit the spread of fire and smoke within the building for a certain period, allowing safe evacuation of people and facilitating the work of firefighters. Examples include a boiler room or a storage area containing flammable materials.

The challenge with chimneys and ducts
When a flue, chimney, or pipe passes through a wall that separates two fire compartments, a problem arises: even if the walls are protected, the fire could spread through the duct. This would compromise the effectiveness of the entire compartmentation.
This is where the wall bushing comes into play — it ensures that fire protection works as an integrated system, preventing heat or flames from spreading to other areas of the building.

How the EI Wall bushing works

- Adapts to different wall thicknesses.

- Conceals the wall opening — no finishing covers are needed.

- Compatible with chimneys and ducts: designed to work both vertically and horizontally in ventilation, smoke extraction, or chimney systems, maintaining safety without affecting system performance.

In short, although it is sometimes overlooked in practice, the wall bushing is the component that guarantees safety in any fire compartmentation. An investment in peace of mind and protection that ensures no small detail compromises the entire installation.
