Abstract
A sound insulating structure (,) comprises first layer plates (,) arranged in coplanar and contiguous relationship in order to form a first structural layer, second layer plates (,) arranged in coplanar relationship in order to form a second structural layer in spaced parallel relation with the first structural layer, and a core (,), which core effectively bridges the space between and adheres together plates of the respective layers, and which core comprises an elastic, vibration deadening mass. At least one through opening is provided in each of the second layer plates with the purposes of permitting escape of any trapped air and of permitting inspection of the space between the structural layers while the mass in the core sets to an elastic state. The invention also provides a panel and a method of manufacturing a sandwich board.
