SemperGreenwall first living wall system with fire safety certificate A2 in the market

Sempergreen is proud to announce that its living wall system SemperGreenwall has been awarded the fire safety certificate A2-s2,d0. This fire class is often mandatory in high-rise projects. Sempergreen’s living wall system already had the B-s2,d0 certificate. This means that it was already suitable for project-based applications, including use on escape routes. With the addition of the A2-s2,d0 certificate, the SemperGreenwall now also offers a fire-safe solution for high-rise projects. This makes the SemperGreenwall the first living wall system in the market to meet these very strict fire safety requirements.

Innovative Flexipanel A2 resists fire and heavy wind loads

A SemperGreenwall is a modular living wall system built from pre-cultivated Flexipanels. These panels are extremely flexible, making the system also applicable to curved surfaces or corner solutions. In order to meet the strict safety requirements that often apply to high-rise projects, the standard Flexipanel has been further developed into the innovative Flexipanel A2. This new Flexipanel is not only resistant to fire, but also to other extreme conditions, such as heavy wind loads.

Tested for flashover and combustion values

The potential risks posed by fire in high-rise buildings are very high. The building requirements for high-rise projects are therefore extremely strict. In order to obtain the A2-s2-d0 fire safety certificate, Flexipanel A2 has been subjected to the following tests carried out by Fire Safety Expert Efectis. These tests included combustion values and flashovers.

  • Single Burning Item (SBI) test, compliant with EN 13823
    This test determines the heat release, flame spread, smoke development and the formation of burning droplets.
  • Heat of combustion test (calorific bomb), compliant with EN ISO 1716
    A test to determine the maximum burning value.


The tests have shown that according to the European fire classification (EN 13501-1), Flexipanel A2 barely contributes to the development of a fire and cannot cause melting parts, only a slight development of smoke.

Response to market demand for nature-inclusive and climate-adaptive construction

The SemperGreenwall is the very first living wall system in the market that meets the fire safety requirements for high-rise projects. With the Flexipanel A2 Sempergreen makes it possible for architects and developers to use a fire-safe living wall system for high-rise projects. This answers the market demand for nature-inclusive and climate-adaptive building. 

Residential tower Eden Tower in Frankfurt first project

The first orders for high-rise projects with the application of Flexipanel A2 are already being realized this year, including a residential tower no less than 98 meters high in Frankfurt, called Eden Tower. Sempergreen expects many more similar projects to follow. 

“The impressive 98 meter high residential tower Eden Tower in Frankfurt is the very first high-rise project to be built with a SemperGreenwall that complies with fire class A2-s2,d0.”

Green is often a closing item in the budget. When budget starts getting tight in the last phase of a construction project, the green is then removed from the plan. An unwise decision, because a green wall actually generates money!
