bro, what do you recommend to soundproof 2 wira front doors?
hmmm... most of the time, I would suggest do 4 doors straight. So you can have a balance effect.
As a starter, you can do 1 or 2 layers...
For Wira, you can only use 6mm Insulflex/SuperLon.
I would suggest you to mix Suppression Pads and Propad. But consider the size of Wira doors, you will need 5 boxes of the pads.
Take 3 x Propad and 2 x Suppression Pad, then buy 2 rolls of Insulflex 6mm with self-adhesive. You can buy those that do not come with self-adhesive, but be prepared to suffer from the smell for 1 week.
Do 2 layer and feel the difference.
