I have two large wooden compost bins and the contents used to dry out reasonably rapidly and also cool down quite quickly. So I made 'duvets' for them, out of rock-wool, bubble wrap and plastic sheet.
I knew that moisture would get inside but I wanted to seal them reasonably well so that they did not fill with water when it rained. So I wrapped duct tape[1] around the 'parcels' and used it to tape all of the openings.
[1. Not the genuine stuff. I looked on Amazon for duct tape and bought some silver tape that came up.]
I put them in place in autumn last year and well before the end of the year the tape had started coming off.
They do work, in that the compost stays wetter and gets hotter. However the tape had pretty much all come off by this spring and when it rained they did fill with water, so removing a duvet to stir the compost risked me getting covered in water.
I know it is asking a lot of the tape to stick when the environment is wet and hot (often >50°C) but I had hoped for more than a couple of months.
What should I do to make these hold together longer? Would genuine duct tape work? Is there something else that is better?
