Sound-Mat

Underlayment

Sound Attenuation

Sound insulating systems greatly reduce impact noise transfer between floors and stop flanking sound. This can be extremely important in the construction of multi-family buildings, hotels/motels, and dormitories. The system consists of the installation of a sound mat onto the floor, a perimeter isolation material is installed around the seam between floor and wall, and then a topping of gypsum underlayment is poured. Generally, LevelRock 2500 is the preferred underlayment to be used, however is not a requirement. Many other underlayments that GBL offer will work.
