Heat transfer in steel buildings occurs in three ways. They are conduction, convection and radiation. These problems can be regulated using proper insulation. Steel building insulation slows down the movement of heat. Insulation can regulate the temperature of these buildings. Steel building insulation also helps to diminish sound by sound absorption. The type and amount of insulation depends on the location of steel buildings. Steel building insulation provides energy savings, noise control and condensation control. There are different methods for steel building insulation.
The most widely used method for insulation is fiberglass insulation. Long strand fiberglass blankets are used for steel building insulation. Fiberglass is laminated on one side to a vapor barrier facing. Fiberglass insulation depends on the thickness of the blanket and the type of facing material. The quality of the fiberglass blanket is related to its thickness. Heat flow slows down with the increasing thickness of insulation.
Facing material is important in fiberglass insulation method. The main function of the facing material is to act as a vapor barrier. Different facing materials vary in their workability, permeability and durability. The workability of a facing material is related to the temperature conditions required for installation. Permeability of a facing is connected to the rate of water vapor. Durability refers to the physical quality of the facing material. The most commonly used facing material is polypropylene. The relative effectiveness of an insulator is determined by R value. R value is used to measure the total thermal transmittance of a material.
Reflective insulation is another method for Steel Building insulation. Reflective insulation is used to maintain the natural temperature. Heat transfer can be regulated using reflective insulation. Reflective insulation is composed of two outer layers of aluminum foil and an inner layer of inert material. Polyethylene or plastic can be used as the inner layer. Fiberglass inner layer gives more insulation power. Reflective insulation is not affected by humidity. It requires no special handling or clothing and is effective in both warm and cold weather.
Spray on insulation is a method for steel building insulation. It can be used for fire protection, moisture and thermal insulation. Spray on insulation consists of a mineral fibre and polyvinyl alcohol. The surface of steel is sprayed using a machine. Polyurethane spry foam can be used for steel building insulation.
