The wood constructing technology of the future

Our patented WLT® technology enables building
aesthetically pleasing structures
with no additives or chemicals

Glue-free wave layered timber

Glue-free wave layered timber is a major innovation that reduces costs of building with wood through a focus on simplicity and flexibility.

WLT®’s ingenious wave shaped profile, combined with it’s specific thermo treatment creates a continuous, crack-free, tight wooden structure.
The wave profile naturally optimizes and regulates the changes of tensions and dimensions due to weather and climate based relative humidity changes.
The WLT® system enables both planning and construction with a secure and controlled, all-natural material.
