Double glazing can typically be installed in many window frames, but it depends on the specific design and condition of the existing frames. Here are some key considerations:
Frame Material: Double glazing can be installed in various frame materials, including wood, aluminium and steel. The frame should be in good condition and structurally sound to support the weight and thickness of double-glazed units.
Frame Design: The frame should have the depth or thickness to accommodate the double-glazed unit. If the existing frame is too narrow or shallow, it may need modifications or a replacement to fit the double glazing. Some unique or historic window designs may not easily accommodate double glazing without altering their appearance.
Frame Integrity: The frame should be free of rot, decay, or structural damage. If the frame is compromised, it may need to be repaired or replaced before installing double glazing.
Compatibility: The type of window, such as casement, sliding, or double-hung, can affect the ease of installing double glazing. Some window types may require more extensive modifications or replacement to accommodate double-glazed units.
Keep in mind that retrofitting existing frames with double glazing can be a complex process, it may be more cost-effective and practical to look towards a single glazed alternative such as a Low E option.
