Insulation Materials for Steel Buildings
Steel framed buildings have several advantages. Steel buildings remain unaffected by ants, termites and other wall boring bugs and even rodents. They are fairly easy to install as they do not require any additional fasteners. Since steel panels do provide protection from external elements, they are not really good at keeping away heat and cold from the buildings. Therefore, insulation is important.
Selecting the right type of insulation is crucial for steel building for many reasons. The right type of insulation:
- Reduces the energy consumption
- Maintains the temperature of the building
- Prevents condensation and controls the moisture of the building which is essential to increase the longevity and improve quality of air inside the building
- Allows you to obtain tax credit in certain states for energy efficient solution
- Buffers unpleasant outdoor sounds
Following are the insulation materials that can be placed in steel buildings:
Fiberglass insulation is a popular choice for steel buildings in United States. It is a good insulator which is used in a variety of constructions. However, when being used with steel, product specifications must be carefully observed. For steel buildings, woven fiberglass with long strands is used. The fiberglass is laminated from one end to provide protection from vapors.
This type of insulation is the least expensive one available in the market because of which the usage is widespread. It is made up of processed fiberglass, rock wool or mineral wood. If it is not installed properly, it will not yield the desired R-value and the inappropriate sealing of air tends to form mildew and mold inside the insulation. Batt insulation is typically used in walls and ceilings and can properly be installed in the stud spacing measuring 16 to 24 inches. Some types of batt insulations come with radiant barriers which reduces the transfer of heat in both the directions.
Rigid Board Insulation
It is composed of either one of the following materials:
This insulation material can be made fireproof with the use of fire retardant material such as gypsum to be used in constructions where the risk of fires is high.
The foaming agent coupled with the polyurethane is sprayed on to the walls, floors and ceilings. The insulation keeps on expanding while being applied until it takes the form of a solid cellular plastic. This is the best method to insulate steel buildings as it does not leave any empty space and fills each and every corner. This type of insulation is obviously more expensive, but it is also more effective and provides a stronger air barrier. As the spray foam insulation is already extremely airtight, it does not really need caulking. Steel foam buildings are highly energy efficient despite the conductive nature of metals because of the insulation provided by foam.
The correct type of insulation if installed efficiently and maintained effectively, makes the steel structures more durable and extremely energy efficient.
