Noise reduction and acoustic insulation for windows and doors

Noise Reduction & Acoustic Insulation

Street noise, stairwell sounds and noise from adjacent rooms penetrate interiors through leaky windows and doors. EPDM seals reduce sound transmission, improving acoustic comfort without costly frame replacement.

How does noise penetrate through windows and doors?

Sound travels through air — every gap in a window or door acts as an acoustic channel through which noise enters the room. Gaps just a few millimetres wide drastically reduce the acoustic insulation capacity of even the best glazing packages, rendering the investment in expensive windows ineffective.

How do EPDM seals improve acoustic insulation?

EPDM seals eliminate gaps at the frame-sash junction, closing the path for sound waves. Flexible EPDM rubber additionally dampens vibrations transmitted through the frame. D, P and E profiles matched to gap size ensure a tight fit without increasing the force needed to close the window.

Benefits of acoustic insulation with seals

Noticeable reduction of street and stairwell noise. Better sleep and work-from-home comfort. Low cost compared to window replacement — sealing one window costs just a few euros. Self-adhesive installation requires no professional help.
