Here is an abstact I found on the silk worm cocoons that will help you understand the composition and thermal properties of the silk. The thermal properties of Bombyx mori silk fibers subjected to heat treatment were examined by thermogravimetry, differential thermal analysis, Fourier transform infrared absorption spectrometry (TG-DTA-FTIR) and scanning electron microscopy (SEM). The color, size, and shape of B. mori cocoon shells were observed as they were heated from 25 to 550°C. Only 1% of the original cocoon shell weight remains as cocoon ash after treatment at 550°C. Inorganic components, such as calcium, potassium, sulfur, magnesium, etc., were detected in the cocoon ash by energy dispersion fluorescent X-ray spectrometry. A sharp decrease in weight was observed in the TG data beginning around 280°C, and an endothermic peak appeared at 308°C, as evidenced by the DTA curves. The IR bands observed at 2380 cm-1 (OH stretching), 1760 cm-1 (CO stretching), 1503 (NH stretching), 1085 cm-1 (CN stretching) and 965 cm-1 (NH2 stretching) become stronger as an exothermic reaction beginning at 280°C takes place. This is probably due to cleavage of the main chain and the accompanying decomposition of the silk fibers. Similarly, a SEM micrograph of silk fibers treated at 300°C shows a microtubule in the middle of the silk fibers of about 25-m diameter. This suggests that the thermal reactions starts in the middle of the silk fiber and forms a microtubule. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 86: 1817-1820, 2002
Yes it is a good insulator
Rubber is an object that is a good insulator.
What is a good insulator for a igloo project
A good insulator is good at stopping heat escaping, whereas a bad insulator is not very good at trapping heat and lets it out.
Yes, air is a good insulator.Yes, air is a good insulator of both heat and electricity
yes silk is a insulator
Silk is an insulator, not a conductor. An insulator is something that does not allow electrical current to flow freely.
it is good heat insulator, as it has air in it. as air is a good insulator of heat, the sponge, which has lots of pockets of air also becomes a good insulator
it depends what type of insulator youre talking about. wood is a good thermal insulator and rubber is a good electrical insulator A perfect vacuum is the best insulator.

its a good insulator and a good insulato
yes carpet is a good insulator.
Yes. Polystyrene is a good insulator.
insulator. it is not a very good insulator though.
