When the local kids work out that throwing stones at it at 3am makes such a noise on your CCTV monitor. That you come charging outside bleary eyed, naked & with a semi lob-on.I'm considering using some osb 3 board 9mm to place onto the sides, inside of course. Not sure why but lol the floor has osb 3 20mm
Boarding it internally will dull the sound & make much more sense mate
