More Free Heat

A few days ago I shot an email to Marvin Windows asking a basic question about using drywall returns as opposed to trimming the interior of the windows with wood. In the same email I gave a short explanation of the project and why I had chosen Marvin. The response I got in return had a little bit of good news. I had chosen Marvin because I could get a special type of glazing called LowE 178 that allows a significant amount of solar gain compared to typical LowE windows. LowE178 has been replaced with LowE 179 whose performance is a little better, and that means more free heat for us!
