Our Enkasonic® Floor Underlayment is an acoustic floor underlayment material made of extruded nylon filaments which form a three dimensional core with a non-woven fabric, heat-bonded to its upper surface.

The durable yet pliable construction of Enkasonic® sound control matting lowers both structural and airborne sound transmission by its ability to convert and store vibrational energy.

Recommended applications for Enkasonic® floor underlayment include commercial and residential multi-story buildings such as condominiums, apartments, office buildings, hotels, schools, athletic floors and more.

Enkasonic® Perimeter Iso is a thin isolation material for use with the Enkasonic sound control material. The product is extremely flexible and light, making it easy to install and handle. The material is sold by the roll 3″ wide x 250′ in length and is 10.16mm (or .400 inches) thick.

  1. :

    Can it be used for carpet padding?

    • :

      Good morning

      Thank you for your interest in Acoustical Solutions.

      The Enkasonic is typically used as part of a concrete underlayment system. It would not be recommended for use a carpet pad.

      You may wish to reference the cross section for carpet and carpet pad when used with the Isosteop floor underlayment at the following link.

      Let me know how I can be of any further assistance.

      Best regards,

    I live in an apartment with noisy floors above. The upstairs apartment will soon be refurbished. Two problems: #1 – joists are loose and squeaky. #2 is bigger problem – no insulation on floor and can clearly hear all sounds above. I will pay for sound-proofing. What are the best products?

    • :

      Thank you for your inquiry regarding the flooring and the issue with the upstairs noise.

      If you will be treating the space that is about to be refurbished, I would seriously consider the Enkasonic Flooring underlayment and Perimeter Iso. It is a footfall isolator and by far the most versatile and easy for contractors to work with. The install method is dependent on the finished floor being used in the remodel so please refer to the install guides or have the contractor review that info to fully understand the system. As for the older, squeaky joists, that can be tightened by the contractor before he applies the Enkasonic.

      For your side of the system, I would strongly consider blowing insulation into your joist cavities and possibly adding a second layer of drywall to your ceiling with the Green Glue product. The usage would be 2 tubes for every 32sq feet of ceiling you would need to cover. Adding the insulation and Green Glue will increase the density between you and your upstairs neighbor and greatly reduce the transmission of noise to your area below, and vice versa.

      If you or your contractor would like to receive a quote for these items please feel free to contact me during normal business hours.

    Please recommend an underlayment to reduce structural/environmental noise on a yacht. Underlayment can be under plywood sub-floor, above or both. The boats and their soles are fiberglass. Thanks,

      Hi Kevin,

      Iso-Step Floor Underlayment offers credible sound reduction of both airborne and structure borne noise with an STC of 31 and IIC of 57. Iso-Step underlayment can be installed over your wood sub-floor and is economically priced and readily available. Please call us with any questions on our acoustical underlayment products at 1-800-782-5742.

    I need an underlayment for my condo that provides a IIC of 61 or an FIIC of 56 over a 7″ concrete slab without a ceiling assembly below.

  5. :

    Can the Perimeter insulation material be trimmed to a narrower width, without fraying the material ?

    • :

      Bill, The perimeter isolation material can have excess trimmed off after installation.

  6. :

    We put a board room in next to gang toilets and you hear the flushing very clearly. We determined that the noise is structural borne (the original wall is fully insulated and we furred out another with an air space between. The furred out wall also has insulation. We had someone sing at full volume in the rest room and it is not audible but the toilet flush is. The toilets are floor mounted so we think it’s transfering to the slab and comming under the walls. Do you recomend any product or systems for this particular issue?

    • :

      Hi Pearce,

      Enkasonic floor underlayment does help with structure borne noise and will have to isolate toilet and pipes from the floor and shared wall to be effective. Check out our other isolation hardware and floor treatments for more options.

    Please recommend a product to reduce noise from air conditioners located on rooftops from proceeding to the floor below.

    • :

      Rick – There are several events occurring here. The 1st is structural noise or vibration. This emanates through the condensers and into the roof structural supports and thereby migrates into the rooms below. This is “heard” as low frequency hum. I suggest 2 things here.

      A) Remove the pad it sits on and lay down a rubber or neoprene mat, then a concrete pad 3-4″ thick. The greater mass slows the vibration. These plastic condenser pads used today actually act like a snare drum and multiply the noise.

      B) install some isolation pads or mounts such as those ASI sells by Mason Industries.

      Next, we can mitigate the airborne noise with a noise screen system. Specifically an absorptive wall needs to be on 3 to 4 sides. The height needs to be at least 2′ above the top of the unit. There needs to be at least 2′ interior clearance between the unit and the walls to maintain airflow. No space needs to be at the bottom other than about 1-2″ to allow for water and snow run off. The screens will reduce noise levels in the 10-15dBa range or a 50% to 75% anticipated noise reduction.

  8. :

    Please recommend soundproofing products for use under carpeting when the subfloor is a concrete slab. Is there a product which does not require plywood layers or a cementitous topping over the soundproofing layer?

    • :

      Michael – We would recommend exploring the QuietPad product, which doesn’t require layers to be applied on top of it.
