Smoke seals doors

The European requirements regarding the smoke-resistance of doors have recently been changed. From January 2021, the European standard EN 1634-3 will be updated. According to this standard, the smoke-proof capacity of the doors is tested separately. As a result the rules for smoke-resistance will be more specific. The new test classifies smoke-permeation according to the S_a and S₂₀₀ values.

S_a
For S_a, the smoke-permeability is tested at a room temperature of 20 °C. The so-called cold smoke resistance. The S_a requirement is applicable in case of partitions in a protected or extra protected escape routes.

S₂₀₀
For S₂₀₀, the smoke permeability is tested at a high temperature of 200 °C. This test for heat smoke resistance - the S₂₀₀ requirement - will apply to partitions between a protected or extra protected escape route and a sub-fire compartment.

The smoke that is released in case of a fire transports a lot of heat which may cause respiratory problems. The smoke also creates reduced visibility and contains aggressive components. The Metaflex smoke-proof door seals the rooms and prevents that the smoke can escape from the burning room and has an EN1634-3 certificate, so that you can rely on this door in all situations.

This means that the door is also suitable for rooms that require a very high protection against smoke, for example because of the limited mobility of those present.
