Definitely recommended deadening with aluminum reinforcement bar that has been in use since its establishment more than 24 years ago!

This deadening has the highest cost performance in our store, and is the aluminum reinforced deadening that we have been working on since the store first opened.
As shown in the photo, we first increase the strength of the door by inserting an aluminum bar on the back of the door, and then apply as much deadening material as possible on top of that.
It is not a bad idea to change the deadening material for the front and back surfaces if they are constructed using the same material, but by intentionally changing the deadening material, we aim to have the effect of canceling out the resonance by changing the resonance between the front and back surfaces.
This deadening is very popular at our store and has a high cost performance that exceeds the cost of the parts used.
