Steel Building Insulation Advantages and Disadvantages
One of the biggest advantages to using insulation in a steel building is that steel panels will conduct hot and cold and by insulating a steel building it will allow you to keep it much cooler in the hot months and much warmer in the cold months.
Another advantage would be avoiding condensation and dripping due to humidity in the air and humidity coming from the concrete not being 100% cured. In both of these cases moisture will build up on the steel panels and cause them to drip. The insulation does not allow the moisture to get to the steel panels on the inside so they will not drip and this is called a “vapor barrier”. The other way a building can get condensation is from the exterior panels frosting up in cold weather areas and then the frost transfers through to the red iron on the inside and during the day when the inside of the building gets warmer, the frost will start to thaw and again cause dripping. When you put metal building insulation over the red iron before the steel sheeting goes down, the insulation will act as a “thermal break” between the outside sheeting and the internal framing so the frost cannot transfer from the outside of the building to the inside and eliminates that type of condensation as well.
The only real disadvantage to steel building insulation is it can trap mold which is an issue in any building in the world. If the building is assembled correctly and maintained properly this should not be an issue. Another issue can be birds getting on the inside of the building and trying to nest and therefore they can sometimes start tearing out the insulation. Again if you maintain the building correctly and chase out any birds it usually isn’t an issue.
The most common type of steel building insulation a fiberglass insulation with a white or black vinyl facing laminated to one side to keep the moisture out. The white or black facing is to the inside of the building. The white facing on the insulation is the most common and because the white facing is to the interior of the building it will reflect light and make the inside of the building much brighter.
There are several types of insulation, for example: fiberglass, rigid or hard board, sprayed on insulation and there are also pre-insulated panels that have insulation sandwiched between 2 steel panels. These can all be used in a metal building and the different types can be used for different applications and building uses. The advantages far outweigh the disadvantages when it come to adding insulation products to your steel buildings.
