I have a problem with noise from my nieghbour and so would like to soundproof my party wall,does anyone know of any soundproofing materials suppliers here in Tenerife?

Goyo's sell sound proofing sheets, various different grades. You put them up the same as a you would a plasterboard wall.

Chafiras builders yard sell the same stuff
