Wood. Naturally. Completely.
Lignum K is a completely wooden freestanding insulating panel, with two external sides in fir combined with a Wood fibre core.
Such excellent combination makes this product unique in its kind, totally ecological with mechanical-physical performances which allow versatile application for covering, attics and walls.
Reduced thicknesses based on the performances
Building a home with Lignum K wood is easy, quick and cost-effective. With an appropriate planning it is not difficult to construct multi-floor buildings because installation of the Lignum K elements is done fast, totally dry and by utilizing normal wood tools.
Easy and quick installation
Besides creating wooden additions, Lignum K is an excellent product also in partial remodelings; internal mezzanines or partition walls can be easily built through a wide selection of finishing for the designer, including even a cost-effective and essential solution, which provides for maintaining the two sides in plain view.
Tests and Certificates
The product has undergone several tests, which have shown than Lignum K guarantees:
- Excellent thermal and sound insulation
- Easiness and quick installing properties through the use of normal woodworking tools
- Contained weight
- Upon request, we have available a wide range of solutions, either in thickness of the wood as well as length of the panels, to offer various static and architectural solutions
- Easy support with wide possibilities of selections of various finishing (plaster or plaster-boards, painting, etc)
- Possibility of eliminating the secondary supporting edge
- Absolutely ecological and natural elements perfectly suitable in Bio-Architecture
- In addition, the type of construction based on laminated wood bearing frame makes the structure stable and without instances of settlements on walls.
- This type of manufacturing gives a remarkable flexibility either for the realisation of a new internal partition wall as well as future removal.
