Performance of aerogel composite and foam insulations
… available insulating materials (three aerogel composite blankets, two extruded poly- styrene foams (XPS) and one blown polyurethane foam (PUR) on plywood ) were evaluated. Thermal conductivity (reciprocal of resistivity) was measured with a heat flow metering apparatus at one week in- …

Advanced thermal insulation for energy efficient buildings : structural performance of aerogel composite panels
Aerogels are well known as exceptional thermal insulators. Thermal conductivities of 9 to 10 mW/m.K have been achieved at atmospheric pressure, and a moderate vacuum (between 1/3 and 1/10 of an atmosphere) can lower this number even further, to around 5 mW/m.K. However aerogels for insulation …

Preparation of silica aerogels with improved mechanical properties and extremely low thermal conductivities through modified sol-gel process
Reported silica aerogels have a thermal conductivity as low as 15 mW/mK. The fragility of silica aerogels, however, makes them impractical for structural applications. The purpose of the study is to improve the ductility of aerogels while retain the low thermal conductivity of silica aerogels. We …
