<p>Hi, </p>
<p>I am working on the facade design for a project and comparing two glass options with frit. In a double glass, if we call the outermost surface '1' and the innermost surface '4', what difference does it have on the glass performance if we add frit on surface
2 vs surface 3? I am getting ready to test this out, but I wanted to see if there was already some study out there that had been done. </p>
