KEIM ETICS are safe.
Day in, day out. In every weather. In case of fire.

External thermal insulation composite systems have to satisfy high, and depending on the type and use of the building, very different requirements in terms of durability, structural stability and flammability.

An ETIC system is really put through its paces before it is approved and can be used. To ensure that the components used actually comply with the system that was originally tested, they are checked regularly in the works and monitored by an independent inspection body.

The declarations of conformity serve as documentary evidence. Together with the certification, the completed company declaration on its last page and possibly any certifications for the insulation material and dowels, these declarations of conformity constitute the complete system verification for your building documentation.

Flammability requirements on ETIC systems

ETIC systems are generally criticised on account of their possible contribution to a building fire. However, one thing that is often overlooked is the fact that different systems have very different flammabilities. The decisive criterion here is the insulation material that is used, though the nature of the render and coatings may also play a role.

All of the mineral render and coating systems from KEIM are non flammable. Together with a suitable insulation material, they thus ensure maximum safety for your building.

Building laws define various minimum requirements on fire protection depending on the type of building. Accordingly, all components or constructions attached to a building have to be normally flammable or better. Normally flammable is therefore the minimum statutory protection objective. It applies for single-family houses or smaller buildings up to a height of 7m, for example. By articulating these protection objectives, legislation wants to ensure anyone inside a building has sufficient time to leave this unharmed in the event of a fire.

The bigger a building or the more people that could be affected, the higher these protection objectives, from hardly flammable to non flammable. Whoever regards this minimum level of protection as inadequate and wants to protect not only lives but also assets should plan to use non flammable systems from the very outset. All ETIC systems should be at least hardly flammable, even in the single-family house sector.

Special measures are needed for this in EPS systems – fire blocks against the internal or external effects of fire.

Flammability of the KEIM ETIC systems

Special case in a wood-frame design on panel materials

B1 acc. to DIN 4102-1 and B s1, d0 acc. to DIN EN 13501-1

On account of the flammability of the load-bearing wooden construction, only certain types of building may be built of wood. This means that non flammable, incombustible systems are not mandatory here. A fire protection assessment is carried out for the overall construction according to is fire resistance pursuant to DIN EN 13501-2.

This is why ETIC systems on panel materials generally only have proof of low flammability. But here again: systems with EPS as an insulation material are only classified as hardly flammable if the thickness of the insulation material does not exceed a limit defined in the permit and the structural fire protection measures named in the permit have been executed, otherwise they are classified as normally flammable.
