Where can I buy alveolar sound-absorbing foam

Good afternoon everyone,

I am new to the forum and not sure I post this in the right section of the forum, but here is my question.

I am willing to insulate a room for audio recording with alveolar foam (or sound-absorbing foam), but I have no idea where to buy it in Bangkok.

I am looking for fair to good quality with a good price, any address of shops or website that may sell such equipment would be greatly appreciated.

If you have an idea of what would be the average price per meter for it (usually sells in 500 x 500mm dimensions) in Bangkok, it would help as well.

Please find picture of such foam below:

Thanks a lot for your help.
