Enclosures for gas turbines are generally required to provide an acoustic barrier, fire protection, turbine cooling and weather protection.  Each enclosure is designed and manufactured to suit the individual requirements of the machine being enclosed.  It can have a simple panel design or be a heavy integrated housing with fire ratings up to A60, manufactured in a wide range of steels, including plastic coated and aluminum.  Additional features can include lifting beams, lighting, fire and gas detection, and protection systems.  An alternative solution is to use heavy plate construction with fiberglass pack walls and ceiling and performance sheet inner panels.
