Insulating a garage - not for heat, but to keep humidity down

[mushymat]

I have a double garage which is actually divided in two. One side is already insulated, the other side is not

The side that’s not insulated is storing wood that’s used for my wife’s business and needs to be kept dry, currently we have a humidifier running more or less 24/7 which is not ideal

The garage is single brick thick with a concrete floor.

With this in mind I need a cheap and easy way to insulate - not for heat retention necessarily but to aid humidity and to maximise the work the humidifier is doing.

My thinking is something like superfoil, but I’d be curious to hear other peoples opinions and thoughts

Cheers all

Where is the water coming from?

Insulation has no effect on humidity , just needs good ventilation. dehumidifiers are very expensive way to do what ventilation will do for free.
