In addition to reducing
reverberant noise, the durable, chemical resistant and water-tight construction of
Sanitary Baffles makes them suitable in difficult environments such as in this swimming
pool.
dB Engineering's Polywrapped Baffles are a
heat-sealed polyethylene bag encompassing a sound absorptive fiberglass fill.
Standard size is 2' x 4' x 1 1/2" thick. Grommets are installed for suspending
from wire or cable ties. White or black facings are standard. These efficient,
economic baffles offer a high NRC rating at an extremely low cost.
