These high temperature resistant blankets are used to retain heat when performing manufacturing or repair operation.  They ensure that heat losses are minimised at the points where required when either using integral heating or individual heater mats.  The blankets are manufactured from a variety of soft woven materials with impermeable surfaces as required. These range from a combination of polyester and glass to aramid, quartz and ceramic textiles.  The filling is generally a mineral fibre or granular material giving a quilted thickness range of 100 - 150 mm.
