Noise Protection IGU
Neigher the color nor the coating of the glass have any effect on its noise protecting qualities. What matters is the following:
- Use of laminated glass.
- Use of tripple glazed insulating units.
- Use of glass with different thickness (asymmetry).
- Increasing the overall thickness of the insulating glass unit.

| 6.5 laminated - 16 - 4 float | 80 | 14 | 3 | 22 | 12 | 72 | 2.7 | 2.5 | 37 | 52 |
| 6.5 laminated - 16 - 5 float | 80 | 14 | 3 | 23 | 12 | 71 | 2.7 | 2.5 | 38 | 56 |

Advantages:
- Can be combined with energy saving or solar protecting glass and acquire high insulating qualities overall.
Disadvantages:
- Higher price.
