Respect, I am not gonna troll these page.
Have questions on 2 things
For anti fire doors,which brand is considered the best in market? What material does it made from?

Second question, for partitions. I recently want to buy a partition wall, and am looking for the hardest partition available on market with sound proofing if possible. Like the one most office use.Which brand/material you recommend? How much does it cost?

Thank you.
