Do you want a simple solution to block noise entering through your windows?

Use our 2" thick SoundAway Mat to create a Window Plug.

What is a Window Plug?  Well, think of it as a sound sponge designed to block, reflect, and absorb  sound.  Our Window Plug is made from a moisture-resistant, flame retardant, 2" thick, black, closed-cell foam.  Simply measure your window, cut our SoundAway Mat approximately 1" greater than the width, 1" greater than the length, and squeeze it into the window frame.  An air-tight fit will offer the greatest relief from traffic noise, noisy neighbors, and many other unwanted sound.

What size do I purchase?

Window Plug Quick Quote RequestMeasure the width and length of your window opening from the inside of your room.  If you need help in determining how many feet of 2" SoundAway Mat you'll need then provide us the dimensions and get a Quick Quote.  We'll take your window measurements and tell you how many feet of Mat you need.

To determine how many feet of SoundAway Mat you'll need start by using the smaller of your window's dimensions as the width.  If your width is less than 48" then round up the length to the nearest foot, new length.  In the shopping cart enter the new length in the Quantity field.  We will cut your Window Plug to the new length you specify.  The maximum length is limited by the length of the roll that is 18' long.  Refer to the illustration below.
