Material of the Soundproof Curtain
As mentioned earlier, soundproof curtains are usually made of dense materials.
These materials are usually used because of their thickness that traps pockets of air, which helps to absorb sound. One example of a dense material used in soundproof curtains is velvet.
Velvet for soundproof curtains has a unique weave method called pile weave structure. Tiny loops of velvet are woven in a single direction which helps to trap air between these loops for better sound absorption and blocking.
Aside from being good at trapping air, velvet is a popular choice of material for soundproof curtains because it has a soft and silky feel.
Another popular material for soundproofing is called Kilo Serge. Kilo Serge is also known as Kilo Wool Serge and is commonly used in recording studios and theatres.
It is made out of several dense layers of wool that traps air and absorbs sound easily. They typically come in solid dark colours and are suitable to be used as curtain lining for other curtains in homes.
