low-E differentiates between long and short waves so solar heat (long wave UV) is blocked one way and infa red shorter wavelengths are also blocked to stop heat leaving the room
So you reckon it helps stop overheating? Because there seem to be completely contradictory opinions on that and I've struggled to find a definitive answer.
The accepted orthodoxy seems to be that it can cause overheating, that's what it says if you google "low e glass overheating"
Low-E glass can trap solar heat energy, which can be beneficial in the winter, but it can also lead to uncomfortable temperatures in the summer. To prevent overheating, installers may recommend using solar control glass in combination with Low-E glass for south and west facing windows.
Which is also what Pilkington say:
The use of low-e glazing helps to retain heat even in winter, allowing you to comfortably use these rooms for more months of the year. Low-e glass is also recommended for north or east facing windows, where a larger proportion of heat loss would be expected. For south and west facing glazing where overheating can become a problem in the summer months, your installer may recommend the use of solar control glass.
By reversed I meant having a setup which keeps out not in, but I think that's basically solar control glass...

“ Your low-E triple glazing - that helps keep heat in but not out right? Or have you reversed it?”
low-E differentiates between long and short waves so solar heat (long wave UV) is blocked one way and infa red shorter wavelengths are also blocked to stop heat leaving the room, what would reversing it do apart from creating differences between the 2 pane gaps?
