What is a lamella in construction?
A lamella roof, also known as the “Zollinger roof” (after Friedrich Zollinger), is a vaulted roof made up of simple, single prefabricated standard segments (mostly in timber) as a way to span large spaces. The individual pieces are joined together with bolts and/or plates to form a rhomboid pattern.

What holds a house roof up?

How are lamellae arranged?
The arrangement of the lamellar bone is similar to a rotated plywood structure, where the fibers are parallel inside a thin sublayer. The fiber direction rotates around an axis that is vertical to the layers (Fratzl and Weinkamer, 2007). The cylinder-like osteons are roughly parallel to the long axis of the bone.
Where are the lamellae located?
the circumferential lamellae (L) run around the circumference of the bone. The inner circumferential lamellae are located on the inner side of the compact bone tissue and the outer circumferential lamellae are located on the outside.
