Due to the corridor width, a double stacked SHEV, compliant to EN12101-2 is required to provide a combined area of 0.9sq/m aerodynamic for corridor smoke extract and 1.0sq/m aerodynamic for fire fighting lobby smoke extract. For simplified integration, performance adherence and demarcation responsibility it is far easier to integrate a SHEV from the same system as your façade system.
A single bottom hung solution is possible however the additional opening angle and distance required can create additional CDM risk (fall from height, product restriction and exposure to high winds when open).
A full height or double stacked side hung SHEV compliant to EN12101-2 is required to provide a combined area of 0.9sq/m aerodynamic for corridor smoke extract and 1.0sq/m aerodnyamic for fire fighting lobby smoke extract. For simplified integration, performance adherence and demarcation responsibility it is far easier to integrate a SHEV from the same system as your façade system.
Where access is required to a flat roof from the corridor, a combined AOV and Access Door is utilised. Compliant to EN12101-2 the door can operate freely on a concealed closer for day to day access and the actuator will engage to automate the door open in a fire condition. A locked solution for increased security is also possible via the addition of maglocks.
The SHEVTEC glazed louvre is tested to EN121001-2 with an aerodynamic free area of 0.9 sq/m for an end of corridor AOV application or 1.0sq/m aerodnyamic for firefighting lobby smoke extract. It is important to consider the overall performance of the façade including U value and weather performance as this product is often glazed into the façade system but does not offer comparable weather performance or u value compared to a tested NSHEV from the same façade system company.
