FAQ: Is Vacuum Insulated Glass (VIG) suitable for retrofitting into typical Australian/New Zealand window frames, especially in older "Queenslander" or "Villa" style homes?

Answer:
Yes, Vacuum Insulated Glass (VIG) is often considered a highly suitable option for retrofitting into existing window frames in Australia and New Zealand, including the timber frames commonly found in older "Queenslander" and "Villa" style homes. Its key advantage in this context lies in its slim profile.

Slim Profile Advantage: VIG units are significantly thinner than standard double or triple-glazing. Typical VIG thicknesses can range from around 6mm to 10mm (8mm for LandVac Vacuum Glazing). This thickness is comparable to or only slightly thicker than single-pane glass, which was originally used in many older homes.

Retrofitting into Existing Frames: The reduced thickness of VIG often allows it to be installed into existing timber window frames without requiring significant modifications to the frame itself. This is a major benefit, especially in heritage homes like Queenslanders and Villas, where preserving the original architectural features is often desired or mandated. Traditional double or triple glazing, with thicknesses ranging from 18mm to 30mm or more, frequently requires deeper rebates or even complete frame replacement, which can be costly and aesthetically disruptive.

Considerations for Retrofitting: While VIG's slim profile is advantageous, successful retrofitting still requires careful assessment of the existing frames

Professional Installation: Proper installation by experienced glaziers is crucial to ensure a good seal and optimal performance of the VIG units within the existing frames.
