Low E glass

[hapnor]

Has anyone researched or thought about Low-E glass? I have a windowsill garden that faces WSW. As you can imagine the afternoon light is intense as I live in N.C. As of yet, none of my Phals or Paphs seem to mind this afternoon blast of light. When I feel their leaves in the afternoons they do not feel hot. I can only assume this is due to the energy efficient windows we have. They are low-e glass. Any thoughts about this?

Is it still warm there? It is often the heat generated by the light that burns the leaves of plants.
My plants have always treated the light they get through my south-facing windows as bright shade. Of course, I am up here in Ohio, further north, and sunny days in autumn-spring are quite rare.

It has been in the 60s/ low 70s. Of course this weekend is a different story.

Here is my current set up. Picture at 15:00.

It has been many moons, but I was the technical manager of the group in a chemical company that invented the practical use of doped tin oxide films for low-emissivity coatings on windows.

While the coating does lower the intensity of the light passing through it in the visible-, and plant-used wavelengths, it does so without substantially affecting the spectrum:
