Glueing of wood, glulam, windows

SP works with bio-based glue, the elimination of formaldehyde emissions and so-called wet glueing. This will include development of test method for joints of wood cement performance, such as long-term properties, moisture resistance, fracture mechanics, and more.

Traditionally, wood is always dried before gluing. New models of glue now make it possible to glue undried timber immediately after sawing. VWet glueing can make huge profits by the rational production and exchange of raw materials while it can provide a higher quality product. Methods not suitable for all products and technology demands of the material, sorting, sizing and drying. Production of wet glueing finger joints is now established, but limited to non-structural applications. This is because the current standards for structural timber does not allow sizing of otorkat wood.


Several studies conducted in recent years have shown that wet glueing finger joints will be as strong or stronger than the corresponding dry joins. One reason may be that wet glueing finger joints may be good penetration of the glue and the wet fingers form a "dense", cohesive joint. Wet glueing can also be used for LAMELLA and edge gluing, but this is still in development stage.
