Stopping condensation in a metal shed

How to stop condensation in a metal storage shed

What is condensation?

Condensation occurs when warm, moist air meets a cold surface such as a window, mirror, wall or in this case - metal panels. This process will cause water droplets to form on the internal surface, which in extreme weather can actually freeze inside. The risk of condensation depends upon how moist the air is and how cold the shed surfaces are. Consideration must be given to your shed location, as a poor choice of location can increase the risk of condensation build up.

How to avoid condensation in a metal shed

All Asgard metal sheds benefit from our unique roof ventilation system. A series of holes are hidden in the roof eaves (some units have further vents situated in fascia panels), this allows air to flow freely inside the unit, reducing the build up of moisture. For this ventilation system to be effective you must allow sufficient space for air to circulate in and around your shed. This is particularly true if situating your shed near heavily planted areas i.e. near to conifers, trees or bushes. If you situate your shed too near to shrubbery or large garden plants the risk of condensation is greatly increased. Try and allow as much space as possible between shed and foliage.
Some Asgard storage sheds (Motorcycle storage range, The Flexistore garden shed range and large bike garages) have additional vents for even more air flow inside.

Bike Storage

Putting a muddy wet montain bike inside a cold shed will produce a little moisture - this is not condensation as such, but liquid drying off from the mud.  If possible try and clean your bikes before storage - though we know not always possible on a cold day after a long ride.

Motorcycle Storage

The Asgard range of motorcycle storage features not only the standard vent system, but also extra side vents to allow fumes and moisture to escape.  All this ventilation helps to reduce condensation inside your motorcycle garage, keeping your motorcycle in great confition throughout the year.

Tip: After a long ride your bike will be very hot. If you do not allow your motorcycle to cool before storing your inside the unit you will increase the risk of condensation.

Plants and shrubs

Try and avoid getting too close to trees and shrubs to minimise condensation inside your shed.  Overnight - trees and shrubs give off moisture, this will enter your Asgard shed through the ventilation holes and appear to be condensation.  If this happens, you need to trim your hedges!.

"Just a quick note to say thanks for your help and advice about condensation. I put my bike store exactly as you said away from my trees and I have not had a drop of water inside even though it has been freezing cold". Online

Long Term Storage

If you are using your Asgard shed for long term storage, it is important you check the contents periodically for any signs of damp. In extreme weather, it is possible some moisture may form inside the unit. If a small amount of moisture is present, dry it up as soon as possible.

What to do in the event of condensation in your metal shed

Tip: If you have persistent problems with moisture, for example in extreme weather conditions, consider at buying a domestic moisture trap. Available at most DIY stores for a few pounds each.  These will soak up any excess airborn moisture.

Asgard accepts no responsibility for damage caused by shed condensation. It is the responsibility of the customer to periodically check for moisture inside the shed. The customer must then take appropriate actions to reduce or remove the moisture.
