Cavity sliding door extra tall

We would like to install a cavity sliding door one that slides into the wall, there is a cupboard so depending how deep the cupboard is it could just slide into there. We want to make the area more soundproof so are hoping it could go to the ceiling with a small frame around if needed. If there is wood that is slow burning and more fire proof we would want this. In the photos the brown doors is the cupboard and we want the sliding door to cover across this “hall way”
