More about this product

Rubber underlayment engineered for maximum sound isolation.

Why condo, apartment, and multi-family projects specify our thickest underlayment

12mm Pre-Cut Rubber Underlayment

The thickest layer in our underlayment lineup, built to quiet impact noise.

At 12mm, this is the maximum-performance option in our pre-cut rubber underlayment family — sized for projects where sound control matters most, like shared-wall buildings and commercial floors. Rubber underlayment is a pre-cut acoustic layer installed beneath hard flooring to absorb impact noise and vibration.

Lab-Rated Sound Control

Rated IIC 56 and STC 58 for impact and airborne sound isolation — the figures condo boards and building codes ask for.

Glue, Nail, Staple, or Float

Adhere with polyurethane adhesive, nails, staples, or double-sided tape, or free-float it inside a floating floor assembly.

100% Recycled, Made in USA

Manufactured domestically from 100% recycled rubber, so it's an eco-conscious layer under hardwood, laminate, or tile.

Grade & Below-Grade Ready

Installs at or above grade and tolerates areas where moisture may be present — a place foam and felt underlayments can't go.

When the spec sheet calls for a sound rating, this is the roll that meets it.

  • HOA-approved sound underlayment for shared-wall construction where impact noise has to stay contained
  • Commercial installs under natural stone, hardwoods, laminate, engineered wood, or tile
  • Not for use under VCT, vinyl, or linoleum
  • Free-floated in a floating floor assembly, or fully adhered — installer's choice

Details & Specifications

Our 12 mm pre-cut underlayment has been designed specifically for commercial use. When looking for an underlayment that will give you the ultimate in sound absorption and is cost effective, this is it. This flooring underlayment offers all the benefits attributed with rubber underlayment and can be adhered with adhesive, staples, nails or with double-sided carpet tape. This sound proofing underlayment can also be free floated in a floating floor assembly, and can be installed in areas where water may be present. This flooring underlayment can be installed at grade or above grade and a vapor barrier may be needed if specified by a manufacturers' warranty. Also because of this flooring underlayment's inherent compaction characteristics, it is also great to use under synthetic turf.
