The invention discloses a light heat preservation and sound insulation batten. The batten comprises a strip-shaped batten body (100), a male groove (101) is formed in the side wall of one side of thestrip-shaped batten body (100), a female groove (102) is formed in the side wall of the other side of the strip-shaped batten body (100), the shape of the male groove (101) is matched with that of thefemale groove (102), a sound insulation cavity (110) is formed in the strip-shaped batten body (100) in the length direction of the strip-shaped batten body (100), and the sound insulation cavity (110) is filled with ceramic composite materials. Accordingly, the sound insulation cavity of the strip-shaped batten body is filled with the sound insulation materials, in the production process, the strip-shaped batten body and a sound insulation part are combined into a whole, the workload and cost of construction are lowered, the laying efficiency is improved, and the application field is enlarged; the ceramic composite materials replace a traditional sound-absorbing plate, the sound insulation effect is better, the weight is lower, and meanwhile the manufacturing cost and environmental pollution of a sound barrier are lowered, and the market competitiveness of a production enterprise is improved.
