Shaded window material

Hello All,

What is the typical/common material to be used for the shaded window (first 2 rows of windows in the figure below)?

P.S: The shaded window does not mean it is shaded by a shading device rather it is a kind of coated window.

Thanks

If that's from an architectural drawing it looks like frit glazing used in the spandrel portion of a curtainwall/storefront assembly. In lieu of project-specific specifications you could simply choose a manufacturer and product and then use their data. LBNL's Window software is also helpful for calculating the overall assembly performance for windows. The most recent project I worked on spec'd Kawneer products.

Material, 
F09 Opaque spandrel glass, !- Name 
Smooth, !- Roughness 
0.0064, !- Thickness {m} 
0.99, !- Conductivity {W/m-K} 
2528, !- Density {kg/m3} 
880; !- Specific Heat {J/kg-K}

This tutorial might help you. It is for OpenStudio but the same concepts apply in EnergyPlus.
