Where To Buy? - Self Adhesive Sound Proof Sheet To Reduce Aircon Gas Sound Emission

[whitefantasy 0]

Does anyone know where to buy the sheet that can be use to sound proof or reduce the noise that echo from the box-up containing the pipings of aircon?

Because the gas running sound is quite loud & hissing sound always emits out from the box-up panel casing.

Hope someone able to help.
