How to Prevent Condensation on Metal Buildings

By Anna Lockhart. 

Condensation is a major player in damaging metal buildings. Here’s how to prevent it.  

There are many benefits to building structures using metal such as weather resistance and sturdiness, but one of the major drawbacks of metal buildings is the damage that can be done by exposure to too much moisture. Condensation, in particular, is a major factor in metal building damages, and it is important to know why it occurs and how to prevent it.  

Condensation happens when there is a significant amount of moisture in the air, and as temperatures drop, the moisture is released from the air and gathers on the ground and other surfaces. Not only does it occur when there is too much moisture in the air, but also if there is a significant difference in the temperature in the air or environment and the metal building itself.  

For metal buildings, there are two kinds of condensation to consider — visible and concealed condensation. When moisture finds a way inside a structure and collects in cool places such as corners of walls or ceilings, it’s called concealed condensation. Visible condensation, on the other hand, forms on the surface of a structure and will look like water droplets or ice and can usually be seen on hanging fixtures such as lights or exposed pipes.  

Both visible and concealed condensation can cause major damage and concerns as they both contribute to deterioration of metal, rusting or even aid in creating mold spots inside a structure. These damages, once they’ve happened, are a pain to fix or replace. So, it is important to know how to prevent it from happening in the first place.  

Since condensation forms due to the change or difference in temperatures, it’s important to make sure the metal building has a secure thermal barrier. Adding vapor barriers, proper ventilation and the right amount of insulation can make a major difference in padding a metal building against spikes in temperature exhaust.
