Patent ID: 7745005

Claim:
A laminated panel for use in building construction comprising: a first layer of material having an external surface and an internal surface; a second layer of material having an external surface and an internal surface; a layer of glue in contact with the internal surface of said first layer of material and with the internal surface of said second layer of material, thereby to bond together the first layer of material and the second layer of material, said layer of glue being made up of at least two different glues, including a first glue having a first shear modulus and a second glue having a second shear modulus; wherein said first glue is formed in a first pattern and said second glue is formed in a second pattern such that said first glue does not materially overlap said second glue; a third layer of material having an external surface and an internal surface; and a second layer of glue in contact with the external surface of said second layer of material and the internal surface of said third layer of material, thereby to bond said third layer of material to said second layer of material; and further wherein said second layer of glue has a unique shear modulus different from the shear moduli of said first glue and said second glue thereby to provide to said third layer of glue a peak loss factor in a third frequency range.
