Laminated low-E glass for single pane use in historic window?
I need to replace the scratched up glass lites in my large living room window, and I also need a better way to keep some of the solar heat from turning the living room into an oven.
Solar rejecting low-E soft coat is pretty darned good, but generally available only in a two-pane IGU window. I've come across some commercial glass fabricators that make a laminated glass with the low-E soft coat in between, but mostly they are quite thick, like 7mm, so not only a poor fit for the existing window muntins but also probably too heavy.
Wondering if anyone has fully investigated this sort of thing and perhaps found/used a good glass product that's thin and light enough to use as a direct replacement?
