Is a seamless sound absorbing plaster system, that can be applied to flat, curved, compound curved, domed or vaulted surfaces. It is easily repairable, mold, moisture and mildew resistant. High frequency sound absorption is accomplished by allowing sound wave energy to pass through the micro pores in the finished surface, dissipating it into heat energy in the mineral wool. Available in three standard finishes, custom finishes are available. Easy installation.
