$290.00Price
  • 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 2-3/5" unit size
     
    U-value for whole window thermal conductance: .23 Btu/sf/degree F/hour 

     

    Solar Heat Gain Coefficient (SHGC) without grid: .65

     

    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: 70%
