Yes. Double or triple glass is the only glass used here for insulation. Nobody will ever use single glass here.In Russia, do you usually use double or triple glass in the windows for insulation? Single glass seems impossible for somewhere so cold!! Here in England, single glass is the rule although many people are adding double glass.
