ProBanners are custom-produced absorbers that provide an economical way to acoustically treat ceiling (and, in some cases, walls) in large room. Great for reducing reverberation and reflections in gymnasiums, arenas, pools, sanctuaries, restaurants, nightclubs and lobbies, these absorption panels can be either hung horizontally across ceiling. ProBanners are available in vinyl, nylon and fabric coverings in variety of colors. ProBanners hold up in harsh environments and install quickly and easily with supplied hardware. Painted metal washers are supplied with ProBanners for installation. They are Class A fire rating per ASTM E-84 test protocol, so they’re perfect for commercial facilities.
