Hi all,
Just procured a nice 32l cool box for a mash tun with the aim of upgrading the insulation. Box comes apart nicely into an inner and an outer to reveal a massive 5mm of loose polystyrene sheets on all sides and base. Gap is actually 10mm all-round, so plenty of scope for upgrading. I plan to wrap the outside with foil-faced 4mm insulation (3 layers) and a 10-15mm layer of foam depending on which camping mat comes to hand.... but it is the gap I want advice on. Seems to me that there are 3 options;
1. Thicker polystyrene sheet
2. Crazy foam
3. Rockwool loft insulation
The lid is also hollow, so that will more than likely get the crazy foam treatment, filling from one end with two vents at the other.
Any other options?
Regards, Pat
