Description

Premium Carpet Underlayment is durable and effective at reducing both impact noise (higher IIC) and airborne noise (STC).  Product is designed with a mass loaded (MLV) barrier bonded to a high-quality resilient acoustic foam padding.  Barrier layer has excellent damping and stiffness characteristics as well as durability and tear resistance providing optimal sound control at an economic price point.  The foam layer acts to decouple the mass layer from the floor vibrations, creating an effective noise barrier.

Carpet Underlayment is ideal for treating noise radiating from carpeted floors in residential, commercial and maritime applications.  With the ability to significantly reduce noise at frequencies as low as 250 Hz this product is highly effective at reducing speaking frequencies, home theater noise, mechanical equipment, boat engine noise and other noise sources found in living or working environments.

Installation:

Installing Premium Carpet Underlayment is quick and easy in new or existing applications without any specialty tools required.  Roll out the underlayment with the barrier side face up and fit the carpet directly on top.  In cases where a tack strip is used, stop the underlayment at the inside edge of the tack strip and tack the carpet in place. 

Features:

  • Easy to use and install
  • Low cost solution for both noise transmission and privacy issues.
  • No need for additional carpet pad
  • Firm yet comfortable feel
  • Increases both IIC and STC ratings

Applications:

  • Reduces road noise in cars.
  • Can be used in all living areas of a boat to increase comfort and reduce engine noise.
  • Mechanical equipment
  • Homes
  • Offices 
  • Meeting Areas
  • Theaters

How To Order:

Under thick and shag carpets, the 1/2" carpet underlayment is suggested for the best noise reduction.  Below firm carpeting such as indoor/outdoor or thin industrial grades, the 1/4" underlayment may be required in order to give the proper feel underfoot.  Product measures 4.5 feet, when figuring out total coverage, multiply the quantity by 4.5 feet.

  Premium Carpet Underlayment Installation

PRIOR TO INSTALLATION:

MEASURE AND TRIM:

Cut your Premium Carpet Underlayment to the needed length overlapping the tack strips slightly.

  Premium Carpet Underlayment Installation

Be sure to lay the foam layer on the floor with the black vinyl layer facing upwards. Butt the edges together as tightly as possible. A strip of vinyl tape can be used to secure the edges.

   

SECURING THE UNDERLAYMENT:

Once you are done laying out the underlayment, cut the edges to fit in front of the tack strips. We recommend to not staple down the underlayment however if your installer is concerned about movement of the underlayment, you can staple it down at a few points.

INSTALLING CARPET OVER UNDERLAYMENT:
