In this video, witness the remarkable impact of our up to 11 locking points system on sound penetration. As the handle turns, even before the window opens, notice how the sound becomes noticeably louder. Our advanced system evenly compresses three rubber seals around all four corners of the window, ensuring a powerful seal against noise. Pay close attention to the end of the video to experience the profound effect of closing the handle on noise levels. It's the science of silence at work. To learn more, visit www.decawindows.com.
