Fire Resistance in Shaft Covers: Hidden Chimneys of Buildings

Fire Rises from Shaft, Not Stairs

When fire safety is mentioned, fire escapes come to most people's minds first. However, the points where fire spreads fastest and most dangerously in modern buildings are installation shafts that are usually overlooked. These shafts are designed as vertical voids where electricity, water, and ventilation pipes pass, and they act almost like a chimney in case of fire. Heat and flames rise rapidly upwards from these vertical voids and spread to all floors, creating a great danger. For this reason, shaft safety in buildings is of vital importance as much as fire escapes.

EI90 Certified Shaft Covers

The EI90 certified shaft covers we produce serve as a critical barrier preventing the spread of fire along the shaft. The EI90 certificate guarantees that the door does not let flames and heat pass for 90 minutes. This period offers a sufficient time frame for building residents to evacuate safely. EI90 shaft covers ensure both life safety and protection of property by reducing panic and chaos that may occur during a fire.

Preventing Smoke Leakage with Intumescent Seals

Fire is not just about flames; smoke and toxic gases create the deadliest effects in fire accidents. Our EI90 shaft covers are equipped with Intumescent seals. These seals swell when in contact with heat and completely close the gaps between the door and the frame, preventing smoke leakage. Thus, the spread of smoke to upper floors during a fire is prevented, evacuation routes become safer, and additional protection is provided for building residents.

Architectural Harmony and Aesthetics

Fire safety is not only about function; aesthetics is also important. EI90 shaft covers are designed to be integrated without disrupting architectural harmony. Thanks to the surface material, color options, and installation details of the covers, they fit in with the building decoration. Thus, safety measures can be applied without compromising the aesthetics of the space. This combination is the optimum solution in terms of both visual integrity and safety.

Long Life and Durability

Our covers are not only effective against fire; they can be used problem-free for years with long-lasting material and durable workmanship. Steel body, galvanized coating, and quality hinge system preserve the mechanical performance of the covers. With regular maintenance, shaft covers serve as a critical component providing safety throughout the building's life.

Summary

In case of fire, the threat comes not only from stairs but also from overlooked shafts. Thanks to EI90 certified shaft covers and intumescent seals, flame and smoke spread is stopped for 90 minutes. This is of vital importance for evacuation and life safety. Moreover, thanks to its design that does not disrupt architectural harmony, it can be applied without compromising aesthetics. In other words, safety and aesthetics are provided together with EI90 shaft covers. Shaft safety is one of the most important measures minimizing fire risk in modern buildings and should not be forgotten.
