Holz Suttner
Holz Suttner is a family-run solid timber business in Haselbach, Lower Bavaria. Its core product is Dübelholz, dowel laminated timber in which softwood lamellas, mostly spruce, are joined with beech dowels into flat elements without glue. It makes wall, floor and roof elements, timber-concrete composite floors and solid timber houses, with in-house CNC joinery and prefabrication. The acoustic range is based on the Akustik Premium profile. Each lamella is slotted on its exposed face, with a wood fibre absorber filling the cavity behind. The loadbearing element is thus both finished exposed surface and absorber. It is used for ceilings, walls and roofs, for example in day nurseries, schools, offices, and sports and event halls.

Suttner Dowel Laminated Timber Akustik Premium 70
Description
Load-bearing dowel laminated timber element of 40 mm wide softwood lamellas with a filigree look, joined with beech dowels without glue. Each lamella has a slot in its exposed face and a milled cavity behind it, filled with a wood fibre strip. Structure, exposed surface and absorber are thus combined in one component. Used for load-bearing ceilings, walls and roofs, also as the exposed soffit of timber-concrete composite floors, in spaces with room acoustics requirements such as nurseries, schools, offices and halls.
