Jute fibers were chemically modified with benzene diazonium salt to increase their compatibility with the PE matrix. It is important to note that jute is sometimes referred to as the golden fibre owing to its high cash value and its colour. The thermograph of individually three-portion jute fiber presented three stages (from 25 to 180C, from 180 to 280C, and from 280 to 500C) of decomposition [ 17 ]. The soft, flexible nature of the insulation material also ensures it can be packed tightly into voids, enhancing airtightness and therefore maximizing the benefits of its thermal performance.
