Audimute isolé - Sound Barrier and Absorption Sheets - Sound Blocker - Soundproofing Sheets Audimute's isolé is a simple sound solution incorporating sound absorption and sound barrier materials into a single hanging solution. Allows for a portable acoustic environment that addresses both sound absorption and sound isolation needs.Audimute sheets and panels are composed of eco-C-tex, which is Audimute's recycled sound absorption material that is effective, non-toxic, and requires less energy to produce than traditional fiberglass and foam acoustic products.Each sheet also consists of a layer of 1/16" Mass Loaded Vinyl (MLV) sound barrier material. MLV provides dense mass that blocks sound waves that contact it.The combination of materials makes isolé ideal for absorbing and blocking sound that would otherwise reflect and escape through doors, windows, vents, and other weaknesses in the structure.Ideal applications for soundproofing include reinforcing doors, windows, and vents. For sound absorption, isolé can be used anywhere in a room and is most effective when mounted at the first point of reflection. Please Note: When using isolé to help block sound from coming through a door or a window, the sheet should cover the entire door or window for the best result. Sound can travel anywhere air can travel.The amount of sound that will be blocked depends on the application of the isolé along with the frequency and amplitude of the sound. Cleaning Instructions: The sheets are NOT machine washable.Clean with water based cleaning agents, foam or pure, water free solvents. Vacuuming or light brushing is recommended to prevent dust and soil buildup. Features: Designed for sound absorption and sound blocking. The amount of sound that will be blocked depends on the application, sound frequency and amplitude. 0.75 NRC Rating - Absorbs an average of 75% of sound waves that contact the sheet. MLV STC of 20. Each order contains 1 sheet. Easy to Install Durable Safe for Your Health Made in the USA To best soundproof a door, couple isolé with an Audimute Soundproofing Acoustic Door Seal Kit. An isolé Sheet is most effective at blocking sound transfer directly through a door. An Acoustic Door Seal Kit more effectively seals the gaps around a door to block sound that would otherwise travel through.
