Removable insulation blanket

Removable Insulation Blankets are used to insulate engine parts, exhaust piping and components, and industrial process piping and machinery. In particular, applications which use diesel engines, such as power generation, off highway & on-highway vehicles, and marine often require insulation blankets to manage the heat that these engines generate. Removable insulation blankets are typically constructed in 3 layers1. The table and photos below illustrate the construction and materials used in a standard removable insulation blanket. Note that for more demanding and unique applications Firwin offers a wide range of alternative materials and construction. Removable insulation blankets are wrapped around the part to be insulated (an exhaust pipe in this illustration). The blankets are then fastened in place using lacing wire. Other fastening options, while less versatile, do exist, including snaps, straps, springs, and Velcro. The amount of heat reduction achieved by insulation blankets varies with the type of insulation media and its thickness. In the graph opposite, touch temperatures (i.e. the temperature of the outer protective cover) are given for 1” thick insulation blankets using Firwin 1200 and Firwin 1800 insulation media.
