Acousti-Mat 3

Acousti-Mat sound mat also offered as a green product
1. Sound mat is loose laid over the entire concrete or wood subfloor.*

* When using Acousti-Mat SD over corrugated steel deck, mat orientation must be in the same direction as the steel deck flutes.

  Acousti-Mat offers superior sound control
2. Seams between sections of sound mat are adhered with zip-strips or taped.*

*Once the mat has been loose laid, no further penetrations should be made.  Rigid attachments through the sound mat minimizes the sound performance. 
  Acousti-Mat offers acoustical control3. Isolation strips are installed, then taped, around the perimeter of the entire room, to eliminate flanking paths.  Isolation strips are also installed, then taped, around any vertical penetration through the floor.

4. Sound mat is covered with approved Maxxon Underlayment, at a depth† specific to the mat chosen for the application.   To ensure uniform depth and a smooth finish, installers use a "screed" to finish the underlayment surface.  (If Acousti-Mat is installed only in hard surface areas, the underlayment is poured directly over the subfloor in areas to be covered with carpet and pad.)


Sound Control for flooring systems
5. In as little as two hours after the underlayment has been poured, the floor is hard enough to accommodate foot traffic, so light subtrades may continue working.  Total drying time varies depending on the type of finished floor goods to be installed, but is generally completed within 10 to 14 days.
