their R-50 ready to mount hatches with vacuum insulation and magnetic seals ? I need to improve / rebuild my frig box. I don't think I can take it all on quite yet. I saw these hatches and thought I might replace my lid and my (small) front loading door now, I bet that would make a big difference to my 25 year old box.

These pre-fab frames & lids look very nice ... very pricey too. I'm wondering if anyone out there has used these and what you think ?
