I have a square SS freezer
box in my boat and I have noticed when people design and install a new fridge freezer
, they generally have massively thick insulated walls. I was just thinking along the lines of a coffee flask, which has a vacume between the 2 surfaces.
Assuming you could seal it properly, would it be better than say 5 inches of insulation
or am I wasting our time.
Also, if someone can give me the correct spelling of vacume? Don't believe the spellchecker.
Drinking hot tea on a hot day is like banging your head against a wall
. It feels good when you stop.... "Terry" my dad.
