LIGNOLOC® collated wooden nails in mass timber construction 18 November 2021

LIGNOLOC® wooden nails offer the possibility of building ecologically high-quality wooden elements. The environmentally friendly fasteners are ideal for the production of multi-layer mass timber panels and replace aluminium nails and wooden dowels.

There are currently several projects in progress in which CLT (Cross Laminated Timber) is manufactured with LIGNOLOC® wooden nails in addition to gluing. In the production process that has been customary up to now with adhesive alone, the necessary use of a press and the duration of the adhesive drying result in a waiting time of around one hour. By using LIGNOLOC wooden nails, production time can be shortened. This means advantages for the industry in terms of time savings and environment friendliness.

What is new in this innovative process is that each new layer of timber is connected to the layer below with LIGNOLOC wooden nails. The nail connection should apply and hold the contact pressure necessary for the adhesive to cure. This measure means that the wall does not have to remain in a waiting position but can continue to follow the production process. The combination of glue and nail should later be able to absorb the necessary shear forces.

Metal-free and easier to recycle

LIGNOLOC wooden nails can be processed with manual tools and offer smaller companies the opportunity to manufacture their own metal-and-adhesive-free timber elements, which represents a higher added value. Materials nailed with LIGNOLOC are also easier to recycle at the end of their life cycle. Free of steel, they can be shredded in a way that is gentle on the tools and recycled in an environmentally friendly manner.
