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 material offers a short assembly time at the building site because of the prefabricated boards. There is no time need edfor curing. There is no break in the insulation layer and no need for a moisture barrier in walls. The board properties provide a lot of advantages: air tightness, fire resistance, thermal insulation and acoustic insulation and of cource sustainability..

- Big board dimensions: 2,95 m x 16 m with a thickness of up to 40 cm
- Prefabricated boards 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 boards
- Best performance in static and physical properties
