Headquarters of the Luxembourg Scout Organisation FNEL

Rough shell, warm core

Bei dem in Cortenstahl gekleideten Gebäude der FNEL offenbart sich erst auf den zweiten Blick, dass es sich hier um einen Holzmassivbau aus Brettsperrholzelementen von Lignotrend handelt.

Der in helles Holz gerahmte Treppenaufgang harmoniert mit dem Massivholz der in Akustikprofil gekleideten BSP-Decken von Lignotrend.

Helles Weißtannenholz im Veranstaltungssaal: Holztafelwände und materialeffiziente Massivholzdecken mit integriertem Schallabsorber.

Die vorgefertigten Brettsperrholz-Decken-, Dach- und Wandelemente ermöglichten die schnelle Montage auf der Baustelle.

Bei der ebenerdigen Terrasse kommt die Sichtseite der BSP-Deckenbauteile, mit Akustikprofil von Lignotrend, besonders gut zur Geltung.

Unter der Cortenstahl-Verkleidung der Fassade verbergen sich wärmebrückenminimierende U*psi-Dämmständer von Lignotrend mit dazwischen eingeblasener Zellulose-Dämmung.

The FNEL, Fédération Nationale des Eclaireurs et Eclaireuses du Luxembourg (Federation of Luxembourg Scouts), has inaugurated its new headquarters in Luxembourg City. The building, designed by the local architectural firm heisbourg strotz architectes, impresses with its rough building shell made of Corten steel. Only at second glance does it reveal that it is a solid wooden building made of cross-laminated timber elements by Lignotrend, Weilheim-Bannholz, whose warm and friendly interior develops very special interior qualities.

Components used

LIGNO® Rippe Q3 | Ceiling component
Product code: LIGNO® Rippe Q3_275_r0_ssp_z26_p0_a50g_625-12-4_WTL_gb_b0
To configurator To product page
Installation top

Whether the element is open or closed at the top is determined by the area of application. If, for example, the element is to be filled with fill on site as a storey ceiling or roof terrace (LIGNO® Rippe Q3-x), its cavities are open at the top (feature _r0). To guide pipes at the top of the element, a cross grid (_r25, _r50) can be added to some superstructures. For roof superstructures, there is usually a flat closed finish _rg0 (LIGNO® Block Q-x, LIGNO® Block Q3-x or corresponding versions of LIGNO® Acoustic classic).
Installation top
_r0 Open, without cross grid
Statics

The height of the load-bearing webs of the element is variable and determined according to static requirements from load and span. Within the framework of this configurator, the selection is limited to four height ranges. A more precise definition is made later during pre-dimensioning or verification with the LTB-x calculation programme. Bulk volume and/or necessary space for installations can also be decisive for the height.
Statics
_230-290 Medium span
Fire resistance

If fire protection is required, an additional layer is added below the web area (for elements with strip profiles _z26, _z53, _z80, for elements with board profiles Akustik klassik _k50g). Their height determines the fire resistance duration of the cross-section from 30 to 90 minutes. The fire resistance must be statically verified. If there are no requirements, the standard versions _z0 or _k50l are to be selected.
Fire resistance
_z26 REI 30 Fire resistance
Cavity

Panel designs with slat profiles and additional layer can be configured with an additional cavity (_p26, _p53) below the additional layer for installation guides, fixtures or to improve sound absorption. Cables laid there then do not penetrate the fire-protection layer. If required, the cavity is filled with insulating material (_p26mw, _p26ha) to improve acoustic absorption. If no cavity is necessary, the characteristic _p0 is selected.
Cavity
_p0 No cavity
Room acoustics

If the soffit of the element is to have a good sound-absorbing effect, the penultimate layer is configured as absorber _a50g. Otherwise, this layer is configured as a solid wood layer _a0.
Room acoustics
_a50g Integrated absorber
Profile

The visible layer is profiled with joints. The code for profiling indicates in millimetres: Element width, strip width (rounded, from/to if applicable) and joint width (rounded) as well as a letter identification for variants, e.g. with chamfered strip edges or with additional height gradation.

Note: Some profiles indirectly cause exclusions for other configuration options.
Profile
_625-12-4 Slat profile
Wood type

Various wood species are available for the visible layer. For quality reasons, individual wood species cannot be configured for all profiles; for technical reasons, surface treatments are excluded for some wood species.
Wood type
_WTL Silver fir knotless, patterned
Structure

The face is subjected to a brushing _gb as standard, which produces a stronger or weaker structure depending on the type of wood and makes the surface less sensitive to scratches. Alternatively, a smooth sanding _gs can be carried out, or on request a bandsaw cut _grimitated.
Structure
_gb Brushed
Treatment

Depending on the type of wood, the optional application of a surface treatment is possible ex works. Individual colour finishes are always sampled for coordination. For elements in individual lengths, colour treatment is limited to max. 5 m length.

Insulation joist

The lower the U-value of a component and the lower the psi value of the details, the less heat is lost. This is precisely where the U*psi® cross-laminated timber insulating uprights from Lignotrend come into effect: They implement high insulating thicknesses in natural timber and minimise thermal bridges.
