1. A method for connecting at least two wooden panels for acoustic and/or thermal insulation, comprising in a first step a metal plate or a metal strip with a thickness equal to or less than 1.5 mm with teeth, which teeth face a first surface of a first wooden panel is attached in a direction perpendicular to a first surface of the metal plate or the metal strip,
an insulating element is attached on its first surface to a second surface of the metal plate or the metal strip by teeth,
a second metal plate or metal strip with a thickness of 1.5 mm or less is attached to a second surface of the insulating element,
a second wooden panel is attached on a second surface of the second metal plate or strip by teeth, the first and second wood panels,
screws are inserted through the first and second metal plate or metal strips and the insulating element wherein the height of the teeth of the metal plates or strips varies between 10% and 50% of the thickness of the insulating layer and the thickness of the insulating material is less than 3 cm.
