Standard double glazing is normally too thick (20mm+) for historic refunds. Specialists utilize "slim-profile" vacuum glazing or gas-filled systems that are as thin as 6mm or 10mm. These units offer thermal insulation equivalent to modern-day windows while fitting into the original thin glazing bars.
