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. Size wise it is a terrific way to finish out 1" or 2" foam products.

Q: 9. 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
