Single-family house made of LIGNO® in Michelfeld

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).

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.

Fire resistance

Unterhalb des Stegbereichs schliesst sich bei Brandschutz-Anforderung eine Zusatzlage an (bei Elementen mit Leistenprofilen _z26, _z53, _z80, bei Elementen mit Brettprofilen Akustik klassik _k50g). Ihre Höhe bestimmt die Feuerwiderstandsdauer des Querschnitts von 30 bis 90 Minuten. Der Feuerwiderstand muss statisch nachgewiesen werden. Gibt es keine Anforderungen, sind die Standardausführungen _z0 oder _k50l zu wählen.

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.

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.

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.

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.

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.

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.

Bulk volume and/or necessary space for installations can also be decisive for the height.

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.

Element height

Die Höhe der tragenden Stege des Elementes ist variabel und bestimmt sich gemäß statischer Bedürfnisse aus Belastung und Spannweite. Im Rahmen dieses Konfigurators ist die Auswahl auf vier Höhenbereiche beschränkt. Eine genauere Festlegung erfolgt später bei der Vordimensionierung bzw. dem Nachweis mit dem Berechnungsprogramm LTB-x. Auch Schüttvolumen und/oder notwendiger Raum für Installationen können für die Höhe massgebend sein.

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.
