Double glazing consists of two sheets of glass with a small space in between, typically filled with air or an inert gas like argon or krypton. A spacer bar keeps the panes apart and absorbs any moisture, while the whole unit is securely sealed within a frame. This setup creates a solid barrier against heat loss, noise, and condensation.
The Technology Behind Its Performance
Thermal Insulation: The layer of gas or air between the panes slows down heat transfer, helping to retain warmth during the winter and keeping cool air inside during the summer. Some types of glass even come with a special Low-E coating that reflects heat back into the room.
Noise Reduction: The gap between the panes disrupts sound waves, which helps to minimize outside noise. Using glasses of different thicknesses can enhance this effect even more.
How Double-Glazed Units Are Made
- Cutting the glass to the right size
- Cleaning the edges thoroughly
- Inserting a spacer bar with moisture-absorbing material
- Sealing the edges securely
- Filling the gap with air or gas
- Testing the unit to ensure it’s airtight
- Fitting the finished unit into frames made of uPVC, aluminum, or timber
