Tips To Reduce Condensation Concerns In Your New Steel Building

Steel buildings are great additions to your property if you want a barn, garage, or storage shed. Most steel buildings can be erected quickly and inexpensively. You will likely need to pay between $20,000 and $50,000 on average to have a prefabricated steel building erected on your land. The building process should include measures to reduce condensation. Condensation in the metal building can create corrosion around metal hardware used to secure steel sheets together. Water in the building can draw in pests and allow mold to form as well. To reduce condensation concerns, follow the tips below.

Add Insulation To The Building

You may or may not be interested in keeping your steel building warm during the winter months. However, you should not skip the insulation, even if your new steel building is only being used for storage. Insulation should be added to the ceiling area of the building, and the material will need to be secured during the initial building process, so work with your builder to choose the insulation that you desire. 

Insulation will be placed between the red steel or I beams that make up the base structure of the steel building. The steel panels are then placed over the insulation. This helps to create a vapor barrier between the inside of the barn or garage and the steel sheets that make up the structure. Specifically, as air moves up through the top of the building, the insulation blocks the movement of the water in the air.

Steel buildings can be fitted with a variety of insulation materials to help reduce condensation issues. Fiberglass insulation blankets with laminated backing is often the best choice. This type of insulation is made up of fiberglass sheets that are fitted with an aluminum or vinyl facing material. The facing sits against the steel sheeting to block moisture. To make sure the facing material creates an impenetrable vapor barrier, ask your contractor to staple the seams of the facing as fiberglass blankets are placed against one another. 

Allow The Concrete To Cure

Most steel buildings will be erected on a concrete slab, and the steel frame can be added over the concrete once the initial curing period is over. Concrete will harden after about three days, and you can place a good deal of pressure on the material after seven days. However, it will take a full 28 days for the concrete to cure. This means that water will actively evaporate from the material for about one month after installation. This can substantially increase the humidity in the barn or garage space. To reduce water vapor, make sure that windows and doors are kept open for a month. Also, consider adding a dehumidifier to the area. If the space does not have electrical outlets, then purchase a dehumidifier unit that contains silica gel desiccant material. This type of device does not require electricity to draw moisture from the air.

Once the concrete has fully cured, you should invest in a concrete sealing. Moisture can and will move through your concrete, and this typically happens when the exterior surfaces are exposed to rain, snow, and ice. As the water moves through the concrete, it will evaporate inside building space. A deep penetrating sealer is a good choice for the concrete slab. This type of sealer will flow into the pores and capillaries that run throughout the top of the concrete. The silica in the sealer will expand into the openings as it dries and seal them off. This will prevent water from moving up to the top of the concrete slab.

Steel buildings need to be protected from condensation when they are first erected, so make sure that the tips in this piece are followed as your garage or barn is built. Also, speak with your steel building contractor about other ways that moisture problems can be avoided once you start using the building.
