Soundproofing

A quieter room starts with understanding the noise.

Explore how interior window systems work, what affects the result, and how we configure a solution around your space.

Interior window panels fitted to an existing window

How window soundproofing works

An interior panel adds another layer inside your existing window. The panel, the air space between layers, and the seal around the opening work together to reduce sound entering the room.

Set realistic performance expectations

Results depend on the full opening and the type of sound. A useful assessment considers the existing window, available space, and other paths sound can take into the room. No window system can promise to eliminate all noise.

Airborne sound through the window and vibration through the building are different problems.
Remaining sound may enter through walls, vents, AC openings, or untreated windows.
A demonstration illustrates one installation; it is not a guaranteed result for every room.

Performance specifications Soundproofing questions

What affects soundproofing performance?

We consider these factors together. Selecting a mounting style alone does not determine acoustic performance.

Air gap: the distance between the existing window and the interior panel influences the system’s behavior.
Panel thickness: thickness and material affect performance, weight, and handling.
Airtight seal: gaps around the perimeter can undermine a window treatment.
Existing window condition: loose components, damaged seals, and surrounding openings matter.
Noise frequency: low rumble, voices, and sharp transient sounds present different challenges.

Soundproofing configurations

Magnetic panels, compression inserts, split panels, and custom mounting details may all have a role. We recommend the combination based on your windows, noise exposure, access needs, aesthetics, and budget.
