Holiday home on Lake Constance 
made of LIGNO®

A wooden house through and through

Dieses wohngesunde Klimaholzhaus am Bodensee trotzt mit seiner Bauweise auf Stützen den regelmäßigen Hochwassern in der Region.
Im Inneren des Klimaholzhauses sind die Sichtholzoberflächen der Brettsperrholzelemente aus astreiner Weißtanne ein echter Hingucker und maßgeblich für das Innendesign.
Die hellen Sichtholzoberflächen aus Weißtanne wirken elegant und schaffen zugleich ein warmes Raumgefühl.
Das Schwarz der Küchenzeile bildet einen aufregenden Kontrast zu dem Hellen Ton der Holzverkleidung aus Weißtanne.
Die Sichtholzflächen aus Weißtanne werden im Wohnbereich durch ein Fenster in die Natur unterbrochen, das zum Sitzen und Rausschauen einlädt.
Die Sichtholzoberfläche der Brettsperrholzelemente sorgt in allen Räumen für eine helle, aber warme Raumatmosphäre - so auch im Badezimmer mit abgeschrägter Decke.
Die bodentiefe Fensterfront lässt hier viel Sonnenschein ins Innere und betont nochmals die Verbundenheit des Klimaholzhauses mit der Natur.
Die vielen Qualitäten der LIGNO® Bauweise bestärkten die Bauherren bei der Entscheidung für einen Holzbau mit Brettsperrholzelementen.

In Hard on Lake Constance, a “Klimaholzhaus” on stilts helped a flood-prone, difficult to build on holiday house plot to new value. Instead of a cellar, an “open basement” of reinforced concrete serves as a table. The massive timber house stands on top – completely constructed from preconfigured, load-bearing timber wood components but still well protected: So the flood can come! 

Configuration overview 

Components used 

  • LIGNO® Rippe Q3  |  Ceiling component 

    Product code: LIGNO® Rippe Q3_230-290_r0_s0_z0_p0_a50g_625-621-4_WTS_gb_buv
    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 

    _z0 R0

    Cavity 

     

    Panel designs with strip profiles and additional layer can be configured with an additional cavity (_p26, _p53) below the additional layer for installation routing, fixtures or to improve sound absorption.Cables laid there then do not penetrate the fire-protective 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 

    _625-621-4 Closed surface 

    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 

    _WTS Silver fir knotless, plain 

    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.

    Treatment 

    _buv UV-protection stain

    Product code: LIGNO® U*psi F_n_200
    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.
