Thermospray of Lexington applied gray K-13 spray-on acoustical insulation in a soon to open Blue Sushi Saki Grill in Indianapolis last week. The resilient fibers of K-13 cellulose insulation products absorb sounds rather than reflecting them. This reduces reverberation, making speech and music more intelligible. Noise is reduced and the ambient sound quality is greatly improved. This is perfect for a wide variety of building projects including auditoriums, sports facilities, classrooms, cathedrals, restaurants, parking garages, and convention centers.
