Condensation is a natural phenomenon that occurs when the air surrounding an object cools to its dew point, causing water vapor in the air to condense into droplets on the object’s surface. This can be found on the side of every can of cold soda or water bottle you’ve ever consumed. On a chilly winter day, you’ve seen it on the inside of your home’s windows. It’s all over the place, even your shed. That is, unless it is well insulated.

Metal buildings are designed to protect our valuables. They’re fantastic for storing automobiles, equipment, and even your mother-in-law when she comes to visit. Whatever use you have for your metal building, you expect your valuables to be protected from the elements. Steel buildings are designed to be moisture and mold-resistant, but there’s a caveat to that: condensation.

When the outside air has cooled at night, but your shed’s interior remains warm from sunlight, condensation can form. Condensation is a pesky occurrence that can cause a lot of frustration and damage to your important items over time. It can allow mold and mildew to form on clothes and fabrics and cause cars, tools, and equipment to rust. No one wants that. But how do you stop moisture from building up and damaging your things? We’ve got some ideas, so just sit tight!

Problems Caused by Condensation

Condensation is a purveyor of destruction. Those little raindrops clinging to the inside of your metal building’s roof may not seem like much of a problem now, but they can certainly become one! Given enough time, they can wreak havoc on your most valuable possessions. Below, we’ve listed some of the most common forms of damage resulting from condensation.

  • Mold and Mildew

If condensation finds its way into your shed, soft materials like fabric can develop mold and mildew. Not only will this damage your valuables, but it can stand the potential to cause illnesses from airborne particles.

  • Rust

Good ole’ iron oxide. Rust can cause thousands of dollars in damage to exposed metal, including vehicles and essential equipment. If you’ve ever seen a junkyard, you’re aware of how pervasive rust can be on automobiles.

  • Decay

Steel is moisture resistant. Wood is not. If your storage facility contains any type of wood, such as timber, furniture, or woodworking equipment, it is vulnerable to condensation damage. Unprotected wood can twist and decay, inflicting thousands of dollars in damage.

Solutions to Condensation in Metal Sheds

Let’s stop moisture in its tracks! Now that we know what causes condensation and what it may do to your belongings, it’s time to devise a remedy. We’ve listed a few alternative techniques to preventing moisture from entering your metal barn or garage.

1. Have the High Ground

Building your shed or garage on the ground that rests above the surrounding land will ensure that ground-based moisture won’t get into your shed.  Condensation will develop from any surrounding moisture, even dampness on the ground. You’ll see this in action in areas with running water like creeks, ponds, and rivers.  

2. Ensure Proper Ventilation

Ample ventilation is required in your shed to avoid moisture buildup, but too much might actually pull it in. Investing in active fans or even passive ventilation systems for your metal building’s roof might help to drastically minimise condensation. It will not only prevent moisture buildup, but it will also help to reduce the high temperatures that are common in unventilated sheds. High temperatures may wreak havoc on your belongings just as rapidly as wetness does.

3. Insulate! Insulate! Insulate!

Insulation is by far the most efficient way to keep moisture out of a steel construction. Applying either closed or open-cell insulation can help prevent condensation development by creating a strong barrier between the cold outer air and the warmer interior temperatures. 

4. Use a Dehumidifier

Dehumidifiers are a fantastic method of reducing condensation. They normally function by sucking moisture from the air through a chilled coil and releasing surplus water through a hose. Dehumidifiers are an excellent tool, but they must be used in concert with other anti-condensation strategies like as insulation or waterproofing to achieve the greatest effects.

5. Anti-Condensation Paint

It’s really a thing! In fact, it’s a popular option for reducing mild condensation issues found in many basements. It won’t do much against heavy condensations that are substantial enough to drip. 

6. Install Moisture Barriers

The best defense is a proactive one. When first installing your shed, taking the time to install vapor barriers along your foundation, walls and roofing can do wonders for keeping moisture issues at bay.


Water is a common element. It’s everywhere and stopping it might be difficult at times. But don’t worry! The most efficient way to keep moisture out of your storage shed is to plan for it during installation. Using vapour barriers and building insulation during the construction process will prevent moisture from ever appearing. However, if you haven’t already proactively fortified your metal building against the impacts of condensation, following some of the procedures outlined above will be quite beneficial.

Metal buildings like Metal Barns are designed to resist some of the world’s most severe weather. They are frequently designed to endure high winds, storms, rain, and even earthquake activity. They are both water- and rust-resistant. But what about the contents of your building? Condensation may be a difficult problem for many property owners. However, with a little planning and knowledge, you can safeguard your shed and, by extension, your vehicles, equipment, and belongings.
