Pamatio 20 mm Insulation Mat, Auto Self-Adhesive Sound-proofing Foam Mat, Car Sound Insulation Deadener, Noise Acoustic Dampening, Moisture Proof Waterproof, 200 cm x 50 cm (Roll)

Good quality and price but shame about using Royal Mail 48hr as its never delivered on time,,,

Bought this to reduce humming noise coming from air pump. Easy to apply and sticky enough to stay in place. I gave three stars as it's not 20mm thick (15mm) and the backing paper is awkward to remove as it tears into small pieces rather than peeling off as one piece which is what you would expect.

All is good 👍
