Aerogel based insulation material

Currently, an aerogel-based insulation material is developed called Spaceloft by Aspen Aerogels (Northborough, Massachusetts, USA) [82]. Spaceloft is a flexible aerogel blanket currently available in thicknesses of 10 mm and has a thermal conductivity of 13.1mWm K at 273 K, about two to three times lower than... 

Another aerogel-based insulation material is developed for pipe insulation called Nanogel Compression Pack by Cabot Aerogel (Boston, Massachusetts,... 

Since the 1980s a new microporous insulation material based on silicic aerogels is in a test phase. About 60 years ago Kistler from Stanford University developed a method to produce aerogels from silicic material without shrinking them He reacted waterglass with hydrochloric acid, washed out the sodium and chloride ions from the gel, substituted the water with alcohol and dried the gel in an autoclave above the critical point. Other methods begin with tetramethoxysilane for the production of monolithic aerogels.

Three-point bending on an X-aerogel beam specimen allows measurements of flexural modulus and strength. The ASTM standard D790 (Standard Test Methods for Flexural Properties of Unreinforced and Reinforced Plastics and Electrical Insulating Materials) specifies a length/width ratio of 16. The stress [Pg.509]

Since standard insulating materials are very inexpensive compared to aerogel-based materials, there is little incentive for products to use more expensive aerogel insulation unless the amount of insulation is very small or there is a substantial need for improved insulation performance within a very limited thickness. 

Now, Boston-based Cabot Corp. is rolling out the first major commercial application of the silicon-based material window and skylight panels that use aerogels for heat and sound insulation while allowing light to... 

Based on recent developments in the field, it can be stated that aerogels still offer the greatest potential for nonevacuated superinsulation systems and consequently must be considered as an amazing opportunity for sustainable development. This chapter of the handbook bridges the gap between those dealing with thermal insulation properties of aerogel materials in general (Chap. 21) and the various commercial products described in Part XV.
