Sound insulation

Finstral’s high-quality window profiles, special sound insulation glazing and solid joints ensure optimum noise protection.


Sound insulation improves your quality of life

Finstral windows and doors are extremely tight. Even the standard versions offer good insulation. The use of special glazing or Finstral composite window s with an additional sash  can produce a very considerable reduction in noise levels.

The more solid the glass, the better the insulation

Even our standard glazing provides good insulation. We have also developed our own special noise insulation glazing for even greater protection against noise, allowing you to enjoy peace and quiet at home.

Twin-line: the Finstral composite window for optimum noise protection

Our innovative Twin-line composite window s offer the best performance in terms of sound insulation. The additional pane in the outer sash  keeps noise where it belongs: outside.
