Hello Charles,
Interesting question!
When we were considering new windows for our home, I was worried about using Low E glass because I'd heard it prevents orchids from flowering -- I even talked with someone who claimed they had to replace their Low E windows with regular glass because they couldn't get their Cattleyas to flower. When I talked with a Pella Salesman, he was adamant that there was no effect on the flowering of plants. I wrote to the AOS with my dilemma, and the response I got was that the jury was out, but that it might be better to be safe than sorry. I even tried to get someone from our local university to do a study, suggesting they might try to get a grant from the AOS to do it, to no avail.
So we went ahead and purchased Low E glass windows. I should add that there were already Low E Anderson windows in our Sun Room when we purchased the house, and I had not noticed any lack of flowering in my plants. I have Dendrobiums, Zygopetalums, Cattleyas, Bulbophyllums, Encyclias, Epidendrums, and maybe a few others all in South-facing Low E windows. They all bloom, and they do not burn, and they are growing just fine.

Dear Colleagues:
For orchids being grown on a windowsill in a home, what is the effect of Low
E glass, if any, on the orchids? To clarify, Low E glass refers to a
coating that allows a lot of light in the window but restricts the loss of
heat from the house.
Thank you for any help or advice you can render.
