I'm just about to pay a firm £250 to line the ceiling and walls of a 20' shipping container with 20mm of spray foam. I'm as sure as I can be that this is a good move in order to stop the container condensing. Before committing to this, can anyone see any pitfalls :confused:

It will only condense if you have moist warm air inside. What are you using it for?

Or 'plants'! ;) ;)

This Expanding Foam, it doesn't contain lead by any chance does it? Lead is very good at stopping xrays. ;) ;)

storing furniture items and misc items that are affected by condensation when it drips - which it does like hell in the winter!
 
You could also get some desicent. I know of some companies who send out products to areas with high levels of humidity, and they need to use commercial scale desicent packs for each container to help manage the moisture build up.
 
I think to stop condensation you need a through draught, if you seal the container up you're asking for problems, air contains moisture, after all we do live on a little island. Also i use foam for a variety of jobs, fitting UPVC windows, securing skirting boards to the wall etc etc it is one of the best adhesives on the market, sticks to most anything and assumes all shapes so when you need to open your container you'll need an oxy cetaline to open it up. As Einstein would say "nicht gut" :mrgreen: :mrgreen: :mrgreen: :mrgreen:

eh :?: not sure I understand the thing about opening the door with a torch..

but good point about airing. Dont think these ones have vents so perhaps i should be cutting some holes with louvres on the outside as well...
 
Sorry i assumed you were going to spray the doors then close them up, if you did do that it would require semtex to open the doors. I would google hermaticly sealing furniture rather than using foam.
 
Have you looked at Industrial sized Vacuum Bags. Similar to these things you can buy on QVC where you stick your clothes/bedding etc in a plastic bag then attach a vacuum cleaner to a valve and it sucks all the air out.
I'm sure if you google you may find something. Beauty is if you need something, you can retrieve it and either re-use it when you have finished with the item or use it for some other item.
 
Couldn't you just contain the furniture in polythene? Sofas and such like are delivered from the manufactures in very large, very durable polythene bags.

EDIT: AH! Great minds conny. ;)
 
no, I need the container to stop dripping water in the winter :)
