Thermal Breaking vs. Double-Glazing Windows: Which Offers Superior Insulation?

Key Takeaways
- Thermal breaking involves the use of a barrier within window frames to reduce heat transfer.
- Double-glazing uses two panes of glass with a gap filled with inert gas.
- For maximum insulation, opt for windows that have both of these features.
- Panda’s unlimited customization options also include thermal breaking and double-glazing.
What Are Thermally Broken And Double-Glazing Windows
Thermally Broken Windows
Thermal breaking adds a barrier inside the window frame to help reduce heat flow between the inside and outside of a building. This barrier is made from materials that do not conduct heat well, like polyurethane or polyamide.

Double-Glazing Windows
While thermally broken windows improve insulation through the frame, double-glazed windows do it through the glass. They consist of two panes of glass separated by a gap, which is filled with an insulating gas like argon, krypton, or xenon.

Performance Comparison Of Thermally Broken And Double-Glazing Windows

The two layers of glass in double-pane windows ensure better insulation than regular glass.

When To Choose Thermally Broken vs. Double-Glazing Windows
If energy efficiency is your top priority, thermally broken windows are the better choice. However, if budget is a major concern and you live in a moderate climate, double-glazing alone can still promote good insulation and noise reduction without the added cost of thermally broken frames.
Pro Tip: For maximum performance, the best option is thermally broken windows with double or triple glazing.
