How To Prevent Metal Building Condensation

Prefab metal buildings are the cost-effective, quickly-constructed, and immensely customizable way to get the structure you need. However, metal building condensation can be a headache. 

If you need to know how to prevent condensation in metal buildings, you your answer lies below. 

Simple Ways To Avoid Condensation Issues in Your Metal Building

Straightforward steps such as installing proper insulation, maintaining appropriate air circulation, checking for roof leaks, and adding drainage materials can counter condensation in metal buildings.

Read on to find out how these measures prevent condensation problems in metal buildings. 

Choose the Proper Insulation

The primary way to avoid condensation issues is insulation. By regulating the temperature inside a building, insulation makes the interior more comfortable and reduces the risk of excessive moisture. 

Adequate insulation regulates the interior temperature throughout the day and limits surface dew formation. It also prevents contact between the warm, humid air and dry, cool steel panels on a metal building’s interior. However, it is critical to correctly install the insulation so that the heat loss is controlled at the exterior sides of the building. Gaps in the insulation reduce its efficiency and can lead to condensation. 

Opt for continuous insulation products such as rigid foam or a combination like insulated metal panels. Add extra insulation to the ceiling, wall cavities and doors, cold pipes, floor slab edges, and ductwork.

Insulation can also double as a barrier to prevent issues with noise pollution in and around your building.

As a result, the loud sounds of machinery and employees in a commercial structure or repairs and activities in a residential garage won’t bother neighbors or family members.

Improve Air Circulation and Ventilation

Stagnant air leads to moisture accumulation. Proper air circulation and ventilation are important to encourage airflow and lessen the risk of visible condensation. 

Air circulation could be as simple as opening the large roll-up door to your metal structure for fresh air flow.

You can add ceiling vents, run fans, and open windows. A couple of fans to blow the air around can also keep it from getting stagnant. 

Similarly, depending on the size of your building, a passive ventilation system can be enough for the trapped unwanted moisture, fumes, and heat to escape. These passive systems include unpowered louvers and ridge vents. They are energy-efficient, with low initial costs and negligible operating costs. 

However, larger agricultural or commercial buildings need a more robust ventilation system. In such cases, you need supply fans and exhaust fans instead of louvers and ridge vents. Investing in these features will help you maintain a comfortable, cool atmosphere inside the facility. 

Install Vapor Barriers

Water vapor can condense into liquid water and accumulate inside walls, roofs, and crawl spaces. The condensation can cause major damage. That’s where vapor barriers come in.

Vapor barriers  reduce the rate at which water vapor moves through a material. Available as membranes or coatings, vapor barriers form a layer in a metal building’s structural interior. They help prevent moisture from the outside from entering the structure through entry points such as a windows, skylights, doors, floors, foundation sills, etc.

While they reduce moisture, vapor barriers are also useful as radiant heating barriers. This crucial material thus can regulate both the temperature and humidity levels. Installing a vapor barrier also depends on the construction of your home and the climate.

Check for Roof Leaks and Seal Space Between the Ceiling and Insulation

Keep an eye out for roof leaks and seal the space between the ceiling and insulation. Caulking, seam tape, and membranes can all help with weatherproofing. You can also apply a high-elasticity sealant to protect a metal roof from water and extent its lifespan.

Choosing the correct type of sealant and the proper application is vital. Incorrect sealant application, early or excessive joint movement, or inadequate surface preparation can result in cracked sealant, potentially causing the roof to sag and collapse. Go for the most common metal roof sealants: butyl, polyurethane, and silicone.

Properly installing screws is also essential for an effective fastener system. The screws must hit the steel framing and be drilled straight to the correct depth. Screws will fail if they are overtightened or not tightened enough.

Use Drainage Materials Underneath the Concrete Foundation

A clogged drainage system can result in moisture buildup, which can extensively damage the metal panels. To prevent the chances of condensation at ground level, it is necessary to have a proper drainage system. Gutters and downspouts can take water away from the foundation. Retroactively installing a vapor barrier between a subfloor and the ground slab can also be helpful.
