Cross-laminated timber (CLT) 

Cross laminated timber

Cross-laminated timber provides an innovative massive building system for single- and multi -family residential buildings, multi-storey residential and commercial buildings, buildings for business and industry, and for special applications in structural timber constructions. Cross-laminated timber is commonly applied for external and internal walls, ceilings and roofs.

The building system offers a minimum of assembly time at the building site because of its prefabricated elements. There is no break in the insulation layer and no need for a moisture barrier in walls. Production of the elements with single layer boards provides a lot of advantages: air tightness, fire resistance, thermal insulation and acoustic insulation.

- Big element dimensions: 2,95 m x 16 m with a thickness of up to 40 cm
- Prefabricated elements with cut-out doors and windows ready for assembling
- Multi-layer board with crosswise arrangement of lamellas
- Dry building system with a minimum of swelling and shrinkage of the elements
- Best performance in static and physical properties
