Compared to old pipe soundproofing cotton, new one is updating:
1. Updated design: old one has margin in up and down side, new one has no margin, better packing the pipe.
2. Updating thickness: new one is thicker than old one which can improve sound absorption and soundproofing db.
3. Updated width: new one is easier to install than old one.
4. Three layer design, better performance:
soundproofing felt + 3M adhesive + sound absorption cotton
How to install:
1. Remove 3m sealing paper.
2. Use pipe soundproofing cotton to cover the pipe.
