Abstract

A composite acoustic damping batten suitable for interposition between first and second building elements, the composite acoustic damping batten comprising at least two resilient portions, each resilient portion comprising a first face and a second face, the first and second resilient portions of the at least two resilient portions being conjoined such that the first face of the first resilient portion and second face of the second resilient portion are spaced apart from each other forming opposing external surfaces of the composite acoustic damping batten; wherein the first face of the first resilient portion is configured for securable contacting engagement with the first building material; and the second face of the second resilient portion is configured for securable contacting engagement with the second building material.

First claim

The invention claimed is:

1. A composite acoustic damping batten suitable for interposition between first and second building elements, the composite acoustic damping batten comprising:
at least two differently shaped resilient portions, each resilient portion comprising a first face and a second face, the at least two resilient portions being conjoined such that the first face of a first resilient portion and the second face of a second resilient portion are spaced apart from each other to form opposing external surfaces of the composite acoustic damping batten and such that the second face of the first resilient portion abuts the first face of the second resilient portion along substantially the entire length of the composite acoustic damping batten;
wherein the first face of the first resilient portion is configured for contacting engagement with a first building material such that the first building material and the first resilient portion of the acoustic building element are securable together;
wherein the second face of the second resilient portion is configured for contacting engagement with a second building material such that the second building material and the second resilient portion of the acoustic building element are securable together; and
wherein the first and second resilient portions each comprise a complementary mating surface profile, each complementary mating surface profile comprising a protrusion or a recess having a uniform cross section extending along substantially the entire length of the composite acoustic damping batten.

2. A composite acoustic damping batten as claimed in claim 1 , wherein the at least two resilient portions comprise materials which have different Shore hardness measurements as measured on the Shore A durometer scale relative to each other.

3. A composite acoustic damping batten as claimed in claim 1 , wherein one of the at least two resilient portions comprises a material which is harder than the other of the at least two resilient portions when measured on the Shore A durometer scale.

4. A composite acoustic damping batten as claimed in claim 1 , wherein one or more of the at least two resilient portions comprises a material which has a Shore hardness of greater than or equal to 55±3 as measured on the Shore A durometer scale.

5. A composite acoustic damping batten as claimed in claim 1 , wherein one or more of the at least two resilient portions comprises a material which has a Shore hardness of between 30±3 and 55±3 as measured on the Shore A durometer scale.

6. A composite acoustic damping batten as claimed in claim 1 , wherein one of the at least two resilient portions comprises a material which has a Shore Hardness of greater than or equal to 55±3 as measured on the Shore A durometer scale whilst the other of the at least two resilient portions has a Shore Hardness of between 30±3 and 55±3 as measured on the Shore A durometer scale.

7. A composite acoustic damping batten as claimed in claim 1 , wherein one of the at least two resilient portions comprises a material which has a different sound transmission coefficient (τ) than the other of the at least two resilient portions.

8. A composite acoustic damping batten as claimed in claim 1 , wherein one or more of the at least two resilient portions are formed from a range of resilient materials, preferable polymeric materials.

9. A composite acoustic damping batten as claimed in claim 1 , wherein one or more of the at least two resilient portions comprise at least one elastomeric polymeric material selected from the group of materials comprising natural rubber, synthetic rubbers, gutta percha, styrene-butadiene rubbers, nitrile rubbers, polybutadiene rubbers, chloroprene rubbers, isoprene rubbers, halogenated butyl rubbers, ethylene propylene rubber, ethylene propylene diene rubbers, epichlorhydrin rubbers, polyacrylic rubbers, fluoroelastomers, perfluoroelastomers, silicone rubbers and polyether block amides (PEBA's).

10. A composite acoustic damping batten as claimed in claim 1 , wherein one or more of the at least two resilient portions comprises at least one expandable polymeric material selected from the group comprising polyolefins, polyurethanes, polyvinyl chlorides, polyimides, polystyrenes, and polysiloxanes.

11. A composite acoustic damping batten as claimed in claim 1 , wherein one or more of the at least two resilient portions comprises a foamed polymeric material.

12. A composite acoustic damping batten as claimed in claim 1 , wherein the composite acoustic damping batten comprises further resilient portions intermediate the first and second resilient portions.

13. A composite acoustic damping batten as claimed in claim 1 , wherein the resilient portions of the composite acoustic damping batten are separately formed.

14. A composite acoustic damping batten as claimed in claim 1 , wherein the resilient portions of the composite acoustic damping batten are integrally formed.

15. A composite acoustic damping batten as claimed in claim 1 , wherein the first and second resilient portions are configured such that the first and second resilient portions are resiliently biased towards each other.

16. A composite acoustic damping batten as claimed in claim 1 , wherein each complementary mating surface profile comprises at least one retaining formation.

17. A composite acoustic damping batten as claimed in claim 1 , wherein each complementary mating surface profile comprises at least one protrusion on the second surface of the first resilient portion and a corresponding at least one recess on the first surface of the second resilient portion or at least one protrusion on the first surface of the second resilient portion and a corresponding at least one recess on the second surface of the first resilient portion.

18. A composite acoustic damping batten as claimed in claim 1 , wherein the at least two resilient portions comprise at least one pair of side edges.

19. A composite acoustic damping batten as claimed in claim 18 , wherein the at least one pair of side edges further comprises one or more sections selected from the group comprising angled, profiled or stepped sections.

20. A composite acoustic damping batten as claimed in claim 18 , wherein the side edges of the at least two resilient portions are configured to include retaining means to restrain and/or lock the at least two resilient portions together.

21. A composite acoustic damping batten as claimed in claim 18 , wherein the at least one pair of side edges comprise at least one fixing indicium.

22. A composite acoustic damping batten as claimed in claim 21 , wherein the fixing indicium comprises any one of a surface marking, an indentation, a notch or a groove.

23. A composite acoustic damping batten as claimed in claim 1 , wherein the composite acoustic damping batten further comprises a retaining clip, for receiving and retaining at least one of the resilient portions.

24. A composite acoustic damping batten as claimed in claim 23 , wherein the retaining clip comprises a central web, a pair of side arms each extending from a respective edge of the central web, a retaining formation adjacent the end of each of the pair of side arms, and at least one aperture in each side arm for receiving a fixing.
