Yes, the noise plug can be bent and squeeze... It is made of hybrid (open cell and close cell mix) for 20mm and Open Cell for 10mm. Total thickness is 30mm. No glue required and can fit it without problem and it will not drop off....the noise plug can b bend? what material is it?
how about the roof part?
Roof? You may buy insulflex or Superlon 10mm will do.... add on Propad/Suppression Pad to dampen the vibration.
