Despite the fact that metal buildings are always safe from issues such as termites and rotting, these types of buildings are still able to fall victim to issues such as excessive amounts of moisture. In fact, damp insulation can be less effective at regulating temperatures inside a metal building, as this has the ability to promote the growth of mildew or mold, thereby causing the inside of the building to smell musty and possibly cause all kinds of allergy-related issues. Additionally, wet insulation that comes into a constant amount of contact with metal surfaces can result in corrosion, even if metal surfaces have been treated. This is because the fasteners and panels can start to rust, which can lead to a premature amount of failure of these specific materials.
Here are three ways in which condensation can be prevented in metal buildings.
Install Vapor Barriers
First and foremost, perhaps one of the best ways in which condensation in metal buildings can be prevented is to install vapor barriers. This is something that is necessary in order to protect the building itself from condensation, as the barrier is designed to keep moisture from the exterior from being able to penetrate the building, as properly sealing the building envelope is what can help keep moisture to a bare minimum. Furthermore, there are many vapor barriers that are also designed to serve as radiant heat barriers, which simultaneously address the humidity and temperature differential. Thorough amounts of sealing are needed in areas such as foundation sills, windows, and doors in order to ensure that moisture is kept out.
Use the Right Insulation
Another way to prevent condensation in metal buildings is to use a proper and continuous amount of insulation. Insulation that is able to regulate the temperature that is inside a building can help to reduce how much condensation is inside it. Not only will it help to keep the interior temperature from fluctuating as much between both day and night in order to limit how much dew is deposited on surfaces during the overnight hours, but it can also help to prevent warm and moisture-laden air from getting to metal surfaces on the interior of the building. This means essentially that in order for insulation to work in a more effective manner, it will need to be continuous, so only placing it between the metal studs will mean that water vapor will still be able to accumulate between all of the panels and seep into the insulation itself.
Ventilate the Interior
One other way to help prevent condensation in metal buildings is to ventilate the interior of the building. There are all sorts of different reasons as to why moisture may end up occurring inside a metal building, which can result in humidity increasing. In agricultural buildings, for instance, livestock can give off excess amounts of moisture as a result of sweating, breathing, and more. Additionally, heaters that are both oil and gas-based can also create an increase in humidity in these types of buildings. By encouraging an exchange of air between both the interior and exterior of the building, you will be working to help keep things dry, and you can achieve this by simply running a fan or air conditioner compressor, opening a window, or installing screened vents. Dehumidifiers can also help in a few different situations; however, it’s important to keep in mind that these can be costly and also require good amounts of drainage.
