Metal sheds are fast becoming the sought out alternative to the standard wooden shed.
They are chosen over timber sheds because you could overcome a variety of maintenance problems, although, metal structures may suffer from condensation problems.
It’s an issue all metal sheds will have to endure where damp is present in the foundation. This problem will arise if a damp proof course hasn’t been built into the base of the shed.
Naturally, the air inside the shed will be warmer than the air outside, thus leading the condensing of the moisture hitting the cool air.
Condensation isn’t easy to stop which is why it is important to prevent damp from occurring in the first place by constructing the base of your shed correctly:
– Make the concrete base a few inches larger that than the base rail of the shed
– Prevention of damp is most effective when a damp proof membrane is inserted into the foundations – this should be put into the base roughly two inches higher than the surrounding ground level
– The shed’s foundations should be left to cure up to a week once the concrete has been laid; ensure to allow longer curing time if the weather condition is damp
– After you shed has bolted to the concrete base, apply a silicone sealant to the inside of the shed base rails (this should be done on the inside rather than the outside)
If your shed is already suffering from condensation, below are some ways to fix your problem.
One option is to detach your shed from the base and build a timber floor some inches larger than the original base measurements, then this ca be put on raised bearers.
Proceed to fix the shed to the timber floor using wood screws and mastic seal on the inside of the shed base rails. This will enable the air to flow under floor and dry the area out, essentially eliminating the problem.
Note to check that water won’t be able to pool underneath the floor as this method will not work.
Another method of ridding condensation is by cleaning the underside of the roof panels with a methylated spirit, then allowing them to dry.
Purchase polystyrene tiles and attach them to the underside of the roof using a bonding glue. The procedure is best executed on a warm day.
A layer of coating should be added to the tiles and shed roof; keep in mind that this method will not rid the moisture in the atmosphere but it should prevent future condensation now that the shed has been insulated.
