How our soundproofing technology works
  • Multi-layer glass — laminated PVB interlayers and multi-pane configurations absorb sound vibrations before they reach indoors.

  • Gas-filled cavities — argon and krypton fills between panes are denser than air, blocking a wider range of frequencies, including low-frequency rumble.

  • Sealed, reinforced frames — acoustic gaskets and tight seals close the gaps where sound most often leaks through.

How much noise does it actually block?

Construction

Panes

Typical STC rating

Standard double-pane

2

28–32 dB

Laminated double-pane

2

35–40 dB

Triple-pane (Global80™)

3

40–45 dB

Premium acoustic (asymmetrical)

2

45–50+ dB

For reference, a standard window without acoustic upgrades rates around STC 26–28. Ratings of 35 and above provide noticeably quieter results; 45+ handles heavy traffic, airports, and construction noise.

FAQ

Q: Do soundproof windows really work?
A: Yes — high-quality soundproof glass, properly installed, significantly reduces loud noises like traffic, construction, or aircraft. Very low-frequency sound may still be faintly audible, and effectiveness depends on glass configuration, frame sealing and installation quality.

Q: What STC rating do I need to block outside noise?
A: A standard window rates around STC 26–28. Our laminated double-pane package reaches STC 35–40, and our Global80™ triple-pane package reaches STC 40–45 or higher — see the table above for the full range.

Q: How much does soundproofing cost?
A: Soundproofing is an upgrade available on any Seemray window or door, typically adding $150–$400 to the base price depending on size and glass configuration. See pricing on each product line above.

Q: Is soundproofing available on all Seemray products?
A: Yes — the laminated glass, gas-filled cavities and sealed frames that provide soundproofing are available across our full range of windows and doors.

Q: Does soundproofing also improve energy efficiency?
A: Yes — the same laminated and multi-pane glass that blocks sound also improves thermal insulation, and our Global80™ package meets Passive House-level energy performance.

Q: Which Seemray option is best for my situation?
A: It depends on your noise source and budget — see our guide on choosing the most soundproof window for your home for a walkthrough by scenario.
