Soundproofing properties of plastic windows

High-quality sound insulation of windows is a key factor for comfortable living, especially in urban environments. It protects against street noise, creating a quiet atmosphere for relaxation and work.

Main factors of sound insulation

The glass unit plays a decisive role in noise protection. Efficiency depends on:

• Glass thickness — the thicker the glass, the better high-frequency sounds are absorbed.
• Number of chambers — a larger number of air layers improves sound insulation.
• Filling of chambers — the use of argon or krypton increases insulation properties.

The frame design also significantly affects noise absorption:

• Profile thickness determines resistance to vibrations.
• Reinforcing insert strengthens the rigidity of the structure.
• Seals ensure tight fit.

Installation quality

Even the most modern windows lose their properties if installed incorrectly. It is important to:

• Follow the installation technology.
• Use high-quality polyurethane foam.
• Ensure the tightness of all joints.

Selection recommendations

For maximum noise protection, it is recommended to choose windows with:

• Multi-chamber profile.
• Three-layer glass unit.
• Thick outer glasses.
• High-quality seals.

Properly selected and installed plastic windows are able to reduce street noise levels to comfortable levels, creating a cozy atmosphere in the room.
