SOUNDlogix’s underlayment comes in a variety of thicknesses: 2mm, 5mm, 10mm, and 12mm.  We also have the ability to do custom thicknesses up to 19mm. Our underlayment holds great sound reduction properties, our STC, IIC, and Delta IIC are very competitive to all other acoustical rubber underlayment products. SOUNDlogix Delta IIC starts at 22 with our 2mm and goes up depending on the thickness chosen. Our product is derived from 90% recycled material and 10% poly binder. This product is also great for LEED certified projects on two fronts, one being made in the USA and the other for being recycled material.
