What did you think of the two variants? My questions: 1.)What do you think better Brax anti noise exvibration or bitumen mats? 2.) Would Brax anti noise exvibration be enough to dams alone? Question as mann would save weight!! 3.)Have already read carefully in a few Threats about dams!! Have heard that a mixture should not be bad? So to speak Brax anti noise exvibration on the outside sheet of the door & bitumen mats on the inside sheet as well as over the different holes at the inner sheet!! Does it seem plausible to me, what do you think of it?? MFG and thank you in advance!!
