Soundproof Window Insulation

A window plug is a soundproof sponge designed to block, reflect, and absorb sound. We use our 2" thick SoundAway Mat to create our soundproof window plugs. Our soundproof window plugs are made of a closed cell foam material that is moisture and fire-resistant. Installing our window insulation plugs is as easy as measuring your window, cutting the soundproof matting approximately 1-1/2" greater than the width and 1-1/2" greater than the length, then squeezing it snugly into the window frame. An airtight fit will offer the greatest relief from outdoor noise pollution including traffic noise, loud neighbors, and other unwanted sounds.
How much Soundproof Window Insulation do I Need?
To understand how much insulation you need for your window plugs, measure the width and height of your window openings from the inside of the room. If you need help in determining how many feet of our 2" closed cell foam mat you'll need, provide the dimensions to get a Quick Quote. We'll take your window measurements and tell you how many feet of our SoundAway window insulation you need to complete your soundproofing project.
