Metal Garden Sheds are an incredibly popular alternative to traditional timber sheds and outdoor buildings, they are more weather resistant, secure, fire retardant and virtually maintenance free. Although metal sheds suffer from very few of the labour intensive problems associated with other types of shed, they can sometimes be affected by the condition of their surroundings. In a word ‘condensation’!
A high quality metal shed will incorporate design features like ventilation, which should avoid the issue of condensation, however occasionally dampness can be caused by external sources. If there is any moisture in the foundations, the warmer air inside the shed will rise and settle on the cold metal panels. The damp will then condense and drip down, creating a cycle, and once this process is established it is not terribly easy to halt, making prevention rather than cure, a better idea. If you have yet to create the foundation for your metal shed, there are few rules to ensure that condensation never raises its ugly head.
Make your base whether concrete or slab, a few inches larger than the base rail of the shed,
- Place a damp-proof membrane into the foundations at least two inches higher than ground level.
- Ensure that the newly laid foundations of your shed are allowed to cure for around 3-7 days, or longer if conditions are damp. This will avoid creating possible water related problems caused by insufficiently dried concrete.
- When ready, bolt down your shed to the base and apply a silicone or mastic sealant to the inside shed base rails. By applying this to the inside you will facilitate trouble free drainage, while preventing water seepage into the shed.
If you have already constructed your metal shed and base and are currently faced with the problem of condensation, there are still ways of tackling this.
- Remove your shed from its base and place a timber floor which is a few inches larger than the shed base measurements on raised bearers.
- Secure the shed to the wooden floor using wood screws, and mastic seal the inside base rails of the shed.
- Ensure regularly that water cannot stop ventilation by collecting underneath the floor.
- Wait for a nice warm day, and begin by wiping down the underside of the roof panels with methylated spirits.
- When dry attach polystyrene tiles to the underside with spray glue which is designed to bond polystyrene to metal and is impervious to heat and cold.
- This insulation cannot eradicate moisture within your shed, however condensation should no longer be an issue.
