LIGNATUR easy
Standard lengths in stock
Light timber ceilings for clever carpenters!
Easy to handle and assemble
High load bearing capacity, but low dead weight and minimal static height.
Maximum 9 kg/m
Assembly
Perfect fit with double folded joint.
- Fit in first element, position and screw to the support.
- Slide next element to the previous one without leaving a joint and screw together.
- Horizontal screw connection of the elements at a distance of approx. 1.5m (screws Ø 8mm, l = 260mm).
Allow for a relieving joint in the case of larger assembly widths.
T-square bearing
Fast and efficient fastening.
Easy processing
Carefully cut the easy elements using simple tools.
Without waste
Arranging left-over non-structural pieces one after another between the load-bearing elements keeps your budget low.
Assembly example using easy 150mm, standard length of 11m, span of 4.8m:
- Lay six 4.8m long elements (Assembly width of 1.2m)
- Add 4 remaining pieces in a row as non-supporting element
- Continue with supporting elements

Characteristics
The strength characteristics and the stiffness characteristics of the sawn timber used comply with Class C24 as per Eurocode 5.
For easy insulated, REI 30 fire resistance can be proved mathematically.
An = 69`200 mm2/m1
Iy = 97.8 mm4/m1 * 106
g = 33 kg/m2
Rv,z,k = 45 kN/m1
Rm,y,k = 42.7 kNm/m1
An = 82`000 mm2/m1
Iy = 220.4 mm4/m1 * 106
g = 39 kg/m2
Rv,z,k = 63 kN/m1
Rm,y,k = 70.5 kNm/m1
An = 94`800 mm2/m1
Iy = 404.7 mm4/m1 * 106
g = 45 kg/m2
Rv,z,k = 80 kN/m1
Rm,y,k = 102.2 kNm/m1
Aesthetics
easy quality for visible areas by LIGNATUR. Equivalent to gluelam N (quality for visibly areas) according to Gluelam Data Sheet of the Studiengemeinschaft Holzleimbau e.V.
Soundproofing
With or without insulation, the easy elements’ sound insulation is equivalient to a timber beam ceiling or a gluelam ceiling without a floor superstructure.
Heat insulation
- Heigh 110 mm, insulated with Wood fibre: U-value = 0.60 W/m² K
- Heigh 150 mm, insulated with Wood fibre: U-value= 0.42 W/m² K
- Heigh 190 mm, insulated with Wood fibre: U-value= 0.32 W/m² K
Resistances to heat transfer: Rsi = 0.13 m² K/W | Rse = 0.04 m² K/W
Lambda-value: λ Pinewood = 0.130 W/mK
Lambda-value: λ Wood fibre = 0.038 W/mK
Joint insulating strips
Suitable joint insulating strips in rolls are available from your dealer.
Installations
You can install almost all luminaires on normally flammable materials such as wood (LIGNATUR). Luminaires that do not meet the requirements must be specially marked according to EN 60598-1:2008.
