CROSS LAMINATED TIMBER (CLT)

CLT is a category of engineered wooden components. It’s a multiple layer wooden panel made by
gluing together layers of solid-sawn timber. Each layer of the board is usually oriented
perpendicular to adjacent layers and glued on the wide faces of each board in a symmetric way so
that the outer layers have the same orientation. An odd number of layers are being used in the
lay-up. The physical properties of the timber change on the direction at which the force is applied.
By gluing layers of wood at right angles, the panel is able to achieve better structural rigidity in both
directions. CLT can also be used for beams and pillars. The laminations are joined end to end,
allowing for long spans.

CROSS LAMINATED TIMBER (CLT

Despite being five-times lighter than concrete, CLT has comparable strength per weight ratio to
concrete and the multi-layer wooden panel spans in two directions. Buildings using CLT carry the
same strength as concrete while minimizing cost and building time.
