HOW MUCH THERMAL INSULATION IS NECESSARY?
It is essential to understand the product, its temperature, pressure, chemical make-up, and the ambient temperature. Are the temperatures and pressures going to create a life safety issue? If the surface temperature of a pipe is 500 degrees, how much insulation is required for a technician to work on it safely and productively? Is the design for an HVAC ductwork with ducted supply and return or with a return plenum? In one installation, insulating both ducts will give the best result. In the other, insulating the supply duct might be the optimum way to go. It also might be necessary to insulate ductwork to prevent noise pollution, which might be “tin can” noise when a fan starts up or conversations from the office next door. WHAT EFFECT WILL WATER VAPOR HAVE ON THE INSULATION? Differences between the ambient temperature and the system temperature can result in condensation on bare piping. When properly installed, insulation and covering protects the pipe from condensation. When the vap
