Rib elements and box elements

Spans of up to 20 m without load-bearing partition walls, widely spanned ceilings without supports or wide roof overhangs can be safely realized with our products. The load-bearing structures of rib elements consist of ribs positioned at a distance from each other, which are connected as load-bearing chords via an upper planking of laminated veneer lumber or cross laminated timber (CLT/LENO®).
If a smooth soffit is required, if elements have to be designed with insulation or with a corresponding fire protection requirement, then box elements are the right choice.
VARIANTS AT A GLANCE
Ribbed elements
They consist of spaced ribs, which are connected by an upper planking of panel materials as a static load-bearing chord.
Box elements
The use of panel materials as the bottom and top chord increases the fire resistance and load-bearing capacity of box elements.
Composite elements
Ready-to-install LENO® cross laminated timber cover panel prepared for on-site bonding with common HBV variants.
