Nanowood which is made from tiny and stripped down wood fibres have been used by scientists to design a heat insulating material which is both strong and light. Scientists are saying that one day this nanowood which is biodegradable and extremely cost-effective can be used to make greener and more energy efficient buildings. The management of heat in cities is becoming an issue as it is difficult to keep heat outdoors in summers and indoors during winters. The materials for insulation which are being used currently are very expensive and also energy-intensive. Moreover, they are not biodegradable usually and ultimately adds to the ever-growing and piling landfills. Therefore, scientists are trying to reduce the cost of insulating materials used as well as seeking eco-friendly options.

Liangbing Hu, who is an Engineer and a Material Scientist at the University of Maryland in College Park and his team have together developed a dense and very strong material and have termed it super wood by getting rid of a complex polymer which holds cellulose in the wood together like a glue and Hemi cellulose which is another component of the body tissue. In order to develop and designed the heat insulating material, Hu and his colleagues have you moved most of the Hemi cellulose and all of the lignin which is a very good conductor of heat (meaning that it is a bad insulator). The elimination of lignin makes the woody material pure white and allows the reflection of incoming light rather than absorbing of the light.

The scientists of realize that none of wood is better insulator then many other materials and is lightweight, can withstand much pressure, and is the strongest commercially used thermal insulation material. This biodegradable material which is lightweight strong and thermally insulating can be used to build cars, sky scrapers, and also be used for protecting heat-sensitive electronics
