CROSS LAMINATED TIMBER
CROSS LAMINATED TIMBER
Dimensionally Stable. Mass. Timber
Cross laminated timber (CLT) is a solid multi-layer product made from solid timber that is usually used for load-bearing wall or ceiling elements.
CLT can transfer loads into different directions and disposes of an increased dimensional stability due to its multi-layer structure and crosswise gluing.
Innovations of the HASSLACHER Group like the cross laminated timber excellence surface open up new and unique design possibilities for architects, designers and builders with regard to the application of timber in the building and construction industry.
