Website of Lawrence Berkeley National Laboratories in Berkeley on gas-filled pannels.
The LBNL Windows and Daylighting Group has extensive experience with highly insulating windows that use gas fills and multiple layers of glazing materials.
An outgrowth of this research is the development of an opaque thermal insulation technology known as Gas-Filled Panels. Gas-Filled Panels, or GFPs, use thin polymer films and low-conductivity gas to create a device with extraordinary thermal insulation properties.
GFPs are essentially hermetic plastic bags that can take on a variety of shapes and sizes. Inside the outer barrier is a cellular structure called a baffle. Argon gas filling provides an effective thermal resistance level of R-7 per inch, krypton gas provides R-12.5 per inch, and xenon gas provides R-20 per inch.
The conversion between SI and US units of R-value is 1 h·ft²·°F/Btu = 0.176110 K·m²/W, or 1 K·m²/W = 5.678263 h·ft²·°F/Btu
