Reduce Outside Noise by Up to 70% Through Your Existing Windows in Ontario
How does noise travel through your windows?
Outside noise enters a space when sound vibrations pass through glass and air leaks around window frames. Gaps, poor seals, and thin glazing allow noise and drafts to move freely indoors, reducing comfort and energy efficiency.
To limit noise transfer, a window system needs an airtight seal, an insulating air space, and materials that help dampen sound vibration.
