Acoustical Insulation can be used to block sound transmission or absorb sound to control noise frequencies throughout a space. The category of Acoustical Insulation is very broad so we further reduce it down to product subcategories including Acoustical Panel Materials which is made up of Fiberglass and Stonewool insulation core panels, acoustic fabrics, and panel hardware for building DIY wall panels and bass traps. In regards to sound blocking or proofing we have the Green Glue Noiseproofing Product category, the Sound Isolation Clip category as well as Mass Loaded Vinyl which dampen and/or block sound transmission through walls, floors, and ceilings. Lastly, our Sound Accessories category includes putty pads, resilient sound isolation clips, and any other sound related product we carry. Take a look through all of these sub-categories as you may find those random sound-proof materials you were looking for.
