Yang developed superinsulation
articles based on oriented porosity incorporating nanopores.
Silica aerogel, being a superinsulation
material and an acoustic shock-absorber, can be therefore considered as a thermal/acoustical insulator for this task.
"The construction of today demands green energy," says Worcester Tech's Brenner, "whether it's solar and photovoltaic, installing superinsulation
, or using high-efficiency burners.
Table 3 outlines the house's current superinsulation
design after retrofit.
. Of course, air leaks aren't the only way a home loses heat in the winter--heat also travels through solid materials, such as your walls and roof.
Ultra-lightweight aerogel superinsulation
as an MLI replacement.
Hydrogen fuel tanks must have a combination of vacuum barriers and "superinsulation
"--usually multiple layers of aluminum foil and Mylar--and be constructed of materials that won't shatter like glass at ultra-cold temperatures.
A research team at Aspen Systems, Inc., and Aspen Aerogels, Inc., both of Marlborough, Mass., and NASA/Kennedy Space Center, Fla., has overcome these two limitations with their Flexible Aerogel Superinsulation
The Thermal/Acoustical business covers a range of nonwoven and woven products including high temperature insulation, thermal and flame barriers, automotive heat shields, thermal and acoustical systems and cryogenic superinsulation
. The automotive part of this business is the largest segment at Lydall, comprising approximately 45% of total sales.
adds about $5 a square foot to the cost of a house, but McKnight and Klein are convinced that this is a trade-off that pays.
The Cornell campus store, which was built underground, is a model of superinsulation
. Larger stockpiles of coal (extending beyond the existing 45-day supply) should be laid in at such sites before Year 2000.
At the same time, the advent of more highly integrated structures has brought new kinds of problems--such as the now-familiar concern that super-tight construction and superinsulation
can cut heating and cooling needs at the expense of fresh air infiltration.
