Retro Wood provides double glazing units to replace single glazed windows, ensuring you get the full benefit of latest double glazing technology! Double glazing provides two sheets of glass separated by a space bar with different options of Argon gas filled to produce higher insulation qualities. Depending on the windows use, location and height it may also be required to be safety glass to meet the building code requirements. The glazing units are supplied by local glass supply companies who also provide a 10 year warrantee against faulty workmanship or leakages. Retro fitting your existing wooden windows provides the same benefits of a new double glazed window, but retains the original character and save on price.
