Glass blocks
I’m thinking about using glass blocks in a bathroom, but have been told that their insulating value is poor and that the bathroom will always be cold. Is this true? There must be some manufactured to provide a decent thermal layer. Any ideas and/or comments would be greatly appreciated.

R value 1.97 for the 4″
R value 1.75 for the 3″
why would this be less “insulative” than the best windows makes no sense. The biggest issue I have with standard alum windows is how conductive the metal is it brings in the cold. I wonder if the blocks do the same?
glass block is about equal to double pane but less insulative than the best windows. Try this link Decora:
