<td align="left" width="631" valign="top"><!--mstheme--><font face="times new roman, times new roman, times"><font face="Arial">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. </font><!--mstheme--></font></td>
