N/A 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.
1Certain applications may require alternative construction methods – i.e. an extra layer may be added, as in the case of sound or fluid barriers. 2Aluminum coating may separate from fiberglass fabric at 500º F+, but fabric maintains good strength until 1000º F. 3Inch insulation suffices for most applications; however, thickness can be varied based on particular application requirements. 4The stainless steel inner liner may be replaced by a fiber-containing material in cases where fiber containment is a requirement.

N/A 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.

N/A 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.
