Hi Lemer Pax. I'm on the hunt for a very specialist glass that may or may not exist yet. Our charity is planning on a very large scale atrium/greenhouse on a commercial scale. The problem is, is that the plot is right next to many powerful cell/mobile/5g masts so we are looking for a technology with glass that blocks this EMF out entirely. The issue is, we need as much of the suns spectrum to come through at the same time. Even tomatoes under ordinary glass do not receive enough light bandwidth to fully develop all their full nutrient & flavour prowess. Its a massive problem as plants will not grow properly with so much emf smog to deal with, is there a solution? I think the solution might be the Holy grail in glass tech in the very near future, whoever pioneers it. Don't you think so too?
