What to use to prevent condensation in outside garage

[WoodYouLike]

I'm planning on putting some flooring down very soon. My plan had been to put some poly down on the concrete floor and then some of these mats:-


Is this a floating insulation floor? Or would I need something else under this as well? I'm trying to keep this as cheap as possible as well.

I think they a more protection mats: protection against damage to your existing floor. The foam absorbs the shock from heavy movement and/or dropping heavy stuff on it.

A floating insulation floor, in my opinion, is more a (wooden) floor installed floating on top of insulation (Polyfoam). When installing that on concrete/screed use DPM and insulation.

I think the double glazing make it worse...etc

Sorry I obviously didn't make that comment clear. I didn't mean double glaze this garage, I was making a general comment about stopping warm moist air coming into contact with a cold surface.
It's a fact that anything made of steel will go rusty in a shed or pre-fab garage like this one. The way to store tools in a damp environment is to wipe them with an oily rag, but not very practical with weights here. The polythene bag idea sounds worth a try, ideally with packets of silica gel inside.

I've decided to put poly on the floor, then that white foam type stuff usually put under laminate flooring and then the rubber mats.

I will then store the weights and bar inside poly bags with Silicia Gel inside when not in use.

Just want to say thanks to everyone who has posted on this thread. You have been given me plenty of useful ideas.

Yes you're right, I don't think the rusty angle iron on the roof section is helping, maybe a good rub down & paint with spray underseal then possibly pipe insulation or expanding foam ( a bit messy) to keep it warm and also maybe use plastic covered weight instead of metal one.
