Metal Sheds

Right, now for the details!

The base will be constructed from 38mm x 63mm studwork with the 63mm faces uppermost in the diagram below. The 5 horizontal spars are complete lengths, with the shorter spars in between cut and screwed into place (2 x 100mm screws into each end of the short spars, and the side ones held on by metal jointing plates); each and every spar will be wrapped with polythene damp proof course, stapled on as assembly is done.

Once levelled up in the correct position for the new shed, I will then staple 100mm wide damp proof course along the four outer sides of the frame with approx 40mm actually sitting on top of the frame with the remaining 60 hanging over the edge - the intention then is to lay the floor (9mm thick OSB3), screw it down onto the frame, then fold the overhaning half of the damp proof course over the edge of the flooring boards to encapsulate the ends to protect from dampness.

Then, its a case of screwing the building on top of the floor, and hopefully that should be enough to keep dampness at bay.

Should condensation be an issue, I can then line the walls with polystyrene veneer - however, I will wait until I see if its an issue first

 

I'd avoid piercing the DPC if you can, maybe just tuck it under rather than stapling. I do agree that a DPC is essential though, I've got one on mine.

 

Thanks John

I am not sure that it will stay on without staples, as I am intending wrapping all the studwork, but my idea was to wrap with the staples being covered as much as possible? I'll draw my idea in a mo

 

I haven't had time to read all of this but I have a Yardmaster. Bought it in 2006 and never any trouble with it.

Mine's a slightly different style (and bigger) as the panels are horizontal. I've never had trouble with condensation and am not bothered about heat. Paint that has been stored in it has been used some years later with no problem.

You definitely need flooring otherwise you can trip over the framework. I also made a ramp to put down for bringing the mower in and out.

I don't know whether the shiplap style is easier to erect than the one you have but it's really a two man job.

The rats ate through my wooden shed but they managed to get in this one.

Good luck with it.

Thanks @shiney

Here is my plan for damp proofing the base and floor edges:

The light blue is the DPC that will be to the underside (standing on concrete or brick), and the darker blue is the DPC that I will trap between frame and floor to then wrap tight over the edge of the floor before mounting the walls.



(Look at me going all '@DIYDave' with the fancy diagrams )

 

Looks good to me FC.

 

Looks good.

Mine wasn't fancy. We put paving down to make everything level, fixed the shed to it, laid a marine ply floor (picked the plywood up cheap) and covered the floor in freebie lino offcuts.
