This winter I am enclosing a 12' x 20' section of my lean to, this will house my evaporator, sink during the season and will be used for storage of filter press and other maple related equipment in the off season.

I will wrap the outside then place the steel up, I do plan on finishing the inside with steel for easy clean up.

My question is how many of you guys have insulated your sugar houses, I would think it could become too warm towards the end of the season.

Thanks
