R6 2248 Fixed Window
- The 2248 is the primary vision window offering views to the outside. Designed for a typical sill height between 30" & 32". The daylight diffusing grid options offer permanent window treatments built into the outer glazing layers of the window, allowing a wide range of built-in solar control options balanced with an open view.22-1/4" x 48-1/8" x 3-1/2" unit sizeU-value for whole window thermal conductance: .18 Btu/sf/degree F/hour
Solar Heat Gain Coefficient (SHGC) without grid: .61
The addition of the grid reduces the effective SHGC in response to solar orientation. Current R&D seeks to quantify these seasonal benefits according to window compass orientation at a given site latitude.
Visible Light Transmission (VLT) without grid: 66%
