WLT® – Wave layered timber
Glue-free wave-layered timber is a major innovation that reduces the costs of building with wood through a focus on simplicity and flexibility
The ingenious wave profile of WLT® combined with Aalto Haitek’s specially developed kiln drying technique creates a homogenous, crack-free and tight structure. The combination of its wave profile joining technique and the alignment of the components and wood grains provides unparalleled dimensional strength for wooden constructions, making it an ecological and economical alternative even for technically and aesthetically demanding structures.
The component’s wave-shaped surface profile naturally optimises and regulates, with a spring-like effect, changes in tensions and dimensions caused by weather and climate-based humidity changes.
WLT® offers a solution for emission-free wood construction
WLT® elements are suitable for a wide range of large- and small-scale construction projects, including buildings, bridges and curved, tall, thick and thin structures. The massive, breathable structure provides an aesthetically pleasing, insulative, structural and fireproof solution. As a load bearing, fire resistant, insulative and light building component, WLT® is suitable for all the main building parts. The installation of WLT® elements is quick and simple as neither nails nor glue are required.
Different types of wood and chemical-free treatments can be used for WLT®. The WLT® elements can be made from different species and kinds of wood. In Finland, we use Northern pine as the main source of raw material.
