I'm hoping someone on here can help. My Asgard shed, a Trojan I think, has developed serious condensation issues. To the point there's basically a water feature on the internal roof. My commuter bike is a steel e-bike and the chain and cassette on it and my HT (thankfully Ti) are starting to show surface rust.
The air vents are clear and there is space to all four sides of it. Anybody know what could be causing it and possibly ways to remedy? All help gratefully appreciated.
There was a previous discussion on the same subject not long ago.
It might be worth searching for it.
Cheers Bruce. Tried the search function but didn't get any results. I'll try searching elsewhere.
Shockingly the search seemed fine for me:

Thanks Branes
Bugger, not what I wanted to read after placing an order for one this week!
It's pretty normal for a steel structure.
All you need to do is stick insulation to the inside of the roof.
I did mine the other way by making a false roof for mine with osb, a sheet of 50mm insulation board underneath it against the steel and felted on top.
Looks better and no condensation whereas before I had terrible condensation issues.
Any recommendation as to what to use for internal insulation, thanks?
You could get some maybe 25/50mm insulation board, Kingspan type stuff.

Contact adhesive should stick it I'd have thought.
I saw an Asgard shelter in Chorlton only the other week. Neat! Though I am glad I have a garage. Albeit a not very good one.
I'd stick some vinyl on before sticking the insulation board up, that way if you need to remove it any glue won't damage the paint/powder coat of the shed, carpet tiles on the floor might help insulate from the freezing ground and theres self adhesive shed insulation available, it's a bit like gold bubble wrap, might be okay for the walls.
Thanks everyone. I have the wooden floor base in the shed so might glue some tiles on. I'll look at the ceiling advice too.
Avoid putting damp stuff or things that like to be damp like cardboard or cloth in the shed helps. I’ve got 2 asgards and not had condensation but both point south and so get occasional sun to warm them up. Only store bikes and no kit.
I can’t see how insulation board is going to help unless you heat the shed up as it’s not going to change the dew point for condensing moist air.
Don't have an option to only store bikes in there unfortunately. It is also my shed. I commute by bike between three and five times per week. By the time I get home it is too dark to clean and dry the bike. Noted on the card cloth and other materials, thanks. It is tricky as I don't have any other storage space. Odd how it hasn't been an issue for the last eight years.
Has a permanent puddle somehow formed underneath it or the wooden floor base? Maybe that's just getting sodden itself and needs taking out to dry or replacing.
Good call chaos. I didn't think of that. I'll empty it out at the weekend and check. Although the floor doesn't seem wet.
I used artificial grass for the floor rather than a solid base. Easy to shake out and the grass holds mud and other crap.

Did you need to upgrade the gas struts due to the added weight?
I wouldn't use carpet tiles, they'll end up sodden, but AstroTurf might work.
What's the floor of the shed? My suspicion would be that you put a wet bike in, the water drips off, forms a puddle,.that evaporates, condenses, you put the bike back in wet the next day, etc, etc.
Ideally I'd suggest finding a way for the condensation to drain out of the shed after it's run down the roof/walls. If puddles form anywhere, drill some small holes?
If not then the only real solution is ventilation and more of it. Could you hook up a small 12V solar panel and a computer fan so that when the sun does come out (and the water is evaporating) it's blowing the moisture out.
Don’t drill holes as you'll invalidate the guarantee as the shed is fully galvinised and will start to rust. I have 2 sheds zero issues and only time you get condensation is putting wet stuff in the shed. Unibond do a moisture absorber block which might help.
I’ve had a big Asgard shed for several years and never had any condensation issues, until this last week interestingly. I’ve dried it each day and will see if it was an odd occurrence before trying any of the above. 🙂
