Bench heights

Thermometer placement 

Away from the door and heater and at head height!


What wood should you used inside?

What glass should I use?

Double glazed, tempered/heat treated inner pane. Spacing doesn't matter.


Should I have an entrance room to trap the heat?

Rockwool likes to soak up moisture. It's like a sponge. Sheep's wool is the gold standard. You can buy Terra Lana in NZ. It actively absorbs moisture, dries out and releases heat from an exogenous reaction with the water! No wonder sheep are so warm! But this only works if your walls are breathable!
