Being Profitable in Business

Prefabrication is a term used in the construction world to describe the manufacture of construction parts and assemblies offsite under factory conditions prior to transportation/delivery onsite for final assembly or installation. One of the most common examples of prefabricated constructions is prefab steel buildings. These buildings can provide building owners with a myriad of incredible benefits, including remarkable strength and durability, cost efficiency, and great visual impact.

But as expected, most things have two sides—the good and the bad. The major issue with prefabricated steel buildings is that moisture from rain, the ground, the atmosphere, and human activity can build up within the structure over time and cause condensation problems. Moisture/humidity-control systems are required to prevent these problems. 

Take a look at some of the problems that can be prevented by regulating moisture levels within prefab steel buildings.

Damage to the building itself

High moisture levels inside a prefab steel structure can lead to accelerated damage. Over time, the protective finishing applied onto the surface of the steel can degrade and allow water to come in contact with the substrate or underlying metal.

When this happens, corrosion is bound to take place, thus contributing to reduced lifespan of the building. Other non-metal components of the building may also get damaged. When water soaks into fibreglass or wool insulation, for example, it can seriously damage the insulation material and, in turn, undermine thermal efficiency within the building.

Bad indoor air quality

Moisture buildup within a steel building can produce unpleasant odours, which may make it difficult for people to stay indoors without covering their noses in order to protect themselves from the bad smell. In addition to that, high moisture levels can encourage growth of harmful microorganisms like mould and mildew, which can release airborne disease-causing spores indoors.

With that said, unregulated humidity levels compromise the quality of indoor air. As it is not a smart thing to take any chances when it comes to the health and safety of people, it is important to invest in a moisture-control system for your prefab building.

Deteriorated building aesthetics

The presence of dripping water and the growth of mould and mildew within or outside a prefab steel building is always eye soaring. These elements undermine the visual appeal of a structure and should not be left unattended. Otherwise, they'll reduce the value of your asset.

Not all moisture-control systems for prefab steel buildings are created the same, so feel free to talk to your builder about what type of system would work best for your building. To learn more about your options, contact a metal fabrication service.
