Traditional double glazing is typically too thick (20mm+) for historical rebates. Professionals make use of "slim-profile" vacuum glazing or gas-filled systems that are as thin as 6mm or 10mm. These systems provide thermal insulation similar to modern-day windows while fitting into the original thin glazing bars.
