The 12" CornerFill Cube is a 12" x 12" x 12" cube of flat-cut Studiofoam acoustic absorber that is beneficial in two ways.

Aesthetically, it provides a smooth, clean edge against which to butt other acoustic wall treatments and acoustic foam bass traps for a more professional appearance. It is a terrific way to finish out trihedral corners where three LENRD Bass Traps come together.

Acoustically, it smoothes out the excess low frequency energy that congregates in room corners and is great for gyms and larger rooms.

A: There are no markings on the panels themselves, but I trust B&H. I have used them to wrap my multimedia room and they work great. I did not buy the Auralex adhesive, and used a spray can of 3M Super 77 (from Home Depot) and it works great.

Q: 7. Can these put put over windows too?

A: Hi Ana - Thanks for your question. Brent is correct in that these Studiofoam Panels can be used to cover a window or any other surface. Sometimes this is referred to as a window plug. If you are wanting this to be temporary I would recommend using a backing of some kind to adhere the panels to - like cardboard or rigid plastic cut to the size of the window opening. There are also lots of DIY tips on the web that can you help you come up with a solution. Hope that helps answer your question!

Q: 10. How do these attach to wall?

A: Greetings Kelley, There are a few options for adhering them to the wall. FoamTak Spray adhesive and TubeTak Pro adhesive applied with a caulk gun. These options are permanent. For a more temporary application you could use the adhesives to glue the Wedgies to a cardboard or poster board as a backing. Then hang them as a group on picture frame hooks by carefully piercing the backing. They can also be hung with finishing nails tacked carefully through the Studiofoam at an angle without going all the way through. As mentioned by a community member velcro strips can be used but sometimes fail in sticking to the Studiofoam. Best regards, Kevin
