Our PolyPhon™ Polyester Acoustic Ceiling Tile is a quick and easy sound absorption solution for drop tile suspended grid systems. The manufacturing process utilizes 60% recycled polyester fiber to create a sustainable, Eco-friendly and recyclable product. These ceiling tiles are a great alternative to standard ceiling tiles. Many generic ceiling tiles are manufactured using loose mineral fibers and tend to crumble, creating dust and loose particulates that can irritate skin or eyes. The PolyPhon™ Ceiling Tile provides you with a durable and clean material to use for T-bar ceiling grid applications.
