Die Lindner ECO_N® ist die erste Hybridfassade unter unseren Elementfassaden. Als statisch wirksame Komponente leistet das Holzmodul – abhängig von der jeweiligen Ausführungsart – einen Beitrag zur Reduktion der CO₂-Emissionen um 20 bis 25 % im Vergleich zu einer konventionellen Aluminium-Elementfassade ohne Holzmodul.
Für die Herstellung der Lindner ECO_N® wurden je nach Aluminiumvariante CO₂e-Werte von 131,60 kg CO₂e/m² mit Hydro REDUXA®-Aluminium ermittelt. Eine Standard-Aluminiumfassade liegt im Vergleich bei 175,96 kg CO₂e/m². Die Werte der ECO_N kommen aus der Lebenszyklusanalyse gemäß DIN EN 14067 und ISO 14025 (von Dez. 2024).
Neben der Materialeinsparung ist das System auf Rückbau und Materialtrennung ausgelegt: Die eingesetzten Materialien werden sortenrein verwendet und mechanisch verbunden. Am Ende der Nutzungsdauer können sie getrennt und einer geeigneten Wiederverwendung oder Verwertung zugeführt werden.
Die Lindner ECO_N® ist in den Varianten ECO_N 80 und ECO_N 100 erhältlich. Durch die einheitliche Außenansicht von 80 mm lässt sie sich mit dem Lindner ECO® Aluminiumsystem kombinieren und ermöglicht so ein durchgängiges Fassadenbild auch bei unterschiedlichen funktionalen Anforderungen innerhalb eines Gebäudes.
Ausgezeichnet mit dem "Best of Products 2024"-Award des Architect's Newspaper Magazine in der Kategorie "Structural Systems".

Within the Lindner ECO_N®, the timber module performs a load-bearing function and forms an integral part of the facade construction. The design makes targeted use of the specific properties of timber and aluminium: while areas exposed to water and moisture are located entirely within the aluminium plane, the timber remains protected within the dry zone. This constructive timber protection supports the long-term durability of the system.
The aluminium used is alloy FNAW-6060 T66. A range of PEFC-certified timber species are available for the design, including spruce, fir, larch, Douglas fir and oak. Depending on the desired appearance, different surface finishes can be selected, including stained, oiled or lacquered finishes, as well as a variety of colours.
The two system variants offer different internal appearances: ECO_N 80 has an internal sightline width of 80 mm with a timber/aluminium appearance, while ECO_N 100 has a 100 mm internal sightline with a solid-timber appearance.
The facade construction is designed for straightforward dismantling. Mechanical connections make it possible to separate individual components from one another at the end of their service life and direct them into the appropriate material streams. This creates the conditions for reuse, recycling or other recovery processes. The form of recovery that can actually be achieved depends on the specific project conditions and the recycling processes available.
The individual components can be replaced as required. This supports the long-term preservation of the value of the facade construction.
For building certifications such as DGNB, LEED or BREEAM, the required product and environmental data can be provided on a project-specific basis. Eligibility for credits depends on the respective certification system and the specific building design.
The Lindner ECO_N® is based on the proven system technology of the Lindner ECO® aluminium facade. Clearly defined sealing and functional levels, together with a cascade drainage system, support the reliable long-term performance of the curtain wall facade.
The timber module is protected behind the moisture zone. The patented PA pressure strip further improves the thermal performance of the system.
The construction is designed to meet a range of structural requirements. For the ECO_N 100 variant, for example, wind loads of up to 1.7 kN are possible for an element size of 1.35 × 3.5 m. The specific performance values are verified based on the respective facade build-up and project-specific requirements.
The Lindner ECO_N® meets the requirements for fall protection in accordance with DIN EN 18008-4, Category A and has been tested in accordance with DIN EN 13830: A4 | RE750. The system also has General Technical Approval Test Certificate No. P-0300222-PFB.
Only non-combustible materials are used in the area of the slab connection. Fire and smoke barriers between floors support preventive fire protection. The load transfer between the facade elements and the building envelope is achieved without a direct fire load.
The prefabrication of the facade elements enables production and installation to be planned reliably. Manufacturing and installation by our own installers allows processes to be coordinated efficiently and supports reliable delivery to schedule.
The combination of timber and aluminium offers extensive design possibilities. The visible timber surface creates a natural, high-quality atmosphere indoors. The facade is available either with an 80 mm-wide timber/aluminium sightline or a 100 mm-wide solid-timber sightline.
Externally, the sightline width remains consistently 80 mm, comprising two 32.5 mm-wide cover profiles and a 15 mm-wide joint. This allows the hybrid facade to be seamlessly combined with the Lindner ECO® aluminium system.
Different functional requirements – for example in occupied and moisture-prone areas – can therefore be accommodated within a project while maintaining a consistent facade aesthetic. Different joint patterns, timber species, surface finishes and colours provide additional design freedom. LED strips can also be integrated directly, doubly or indirectly into the facade construction.
The Lindner ECO_N® therefore combines the natural character of timber with the technical performance of a unitised facade, creating a consistent solution for different requirements relating to design, function and use.
