Choosing panel thickness and lamella width

Two decisions shape a solid panel: how thick it is and how many lamellae it is made from. Both change the appearance and how the panel behaves over time.

Choosing panel thickness and lamella width

What thickness determines

Thickness sets how far a panel can span and how well it resists sagging. In shelving supported at two points, thickness has to rise as the span grows.

Thickness also affects edge machining and fixing choices: a thin panel may not leave enough material for screws or dowels.

Lamella width: appearance and stability

A narrow-lamella panel shows more glue lines but is more stable; because each lamella's own movement is small, total movement is distributed and reduced.

A wide-lamella panel gives a calmer surface, closer to a single solid piece — but each lamella moves more.

Questions that make the choice easier

Three questions settle most cases:

  • How far will the panel span and what load will it carry?
  • Will the surface be seen closely — would glue lines be a problem?
  • Does the environment swing widely in humidity? If so, narrow lamellae are safer

Decide it together with the grade class

Panel grade is defined by the AA-AB-AC and BB-BC-CC system, where the first letter describes the visible face. Choosing lamella width and grade class together clarifies the expected appearance.

Send the dimension, lamella width and grade combination with your cutting list and the technical office can work through the choice with you.
