21. The silk is used to manufacture thermal insulation , acoustic insulation and oil absorbents. 22. Vellus hair provides both thermal insulation and cooling for the body. 23. The thermal insulation tiles on the Space Shuttle were coated with a borosilicate glass. 24. Some models have very high thermal insulation properties, making them suitable for zero-energy buildings. 25. Building codes now require thermal insulation and efficient windows for new construction or retrofits. 26. This coating is predominantly used for thermal insulation , thermal protection and its anti-wear properties. 27. The blocks are lightweight and have excellent thermal insulation properties. 28. These models include light-weight polymer panels, laminated with thermal insulation . 29. :: : It also matters whether the electrical insulation also acts as thermal insulation . 30. It is the most damage to the thermal insulation of a shuttle in nine years.
