WECU Information: Guidelines, Installation, Sound Ratings, Warranty & More

Guidelines

(Flooring/Ceiling Sound Isolation)

The purpose of this information is to provide Homeowner’s Associations information relating to the acoustical performance of floor/ceiling assemblies. This should facilitate the HOA in establishing guidelines to meet the needs of their building. This information is for guideline purposes only. Each building is unique. The building should contract with appropriate legal counsel and design professionals prior to incorporation of binding requirements within CC&Rs.

Acoustical Terms

In multi-family dwellings, acoustical consultants use the following terminology to define the performance of a floor/ceiling assembly.

  • STC: Sound Transmission Class. This is a laboratory measurement of the ability of a specific construction assembly (such as a partition, window, door, etc.) to reduce airborne sounds including voice, television and alarm clocks.
  • Noise Isolation Class. This is an over-all measure of the sound isolation between units in a multi-family dwelling. This quantity is a field measurement of the ability of a partition, floor/ceiling assembly, etc., to mitigate airborne sounds including voice, television and alarm clocks.
  • Impact Insulation Class. This is a laboratory measurement of the ability of a floor/ceiling assembly to reduce impact sounds such as footfalls. For more information regarding how IIC ratings are calculated, please click HERE.
  • FIIC: Field Impact Insulation Class. This a field measurement done in situ after a floor installation is completed.

The higher the value of any of the quantities above, the greater the airborne or impact isolation provided by the assembly.

Requirements

Building Code requirements that include Sound Insulation Standards normally require that:

  • Airborne Sound Insulation is not less than STC 50 if laboratory tested, or not less than NIC 45 if field tested.
  • Impact Insulation is not less than IIC 50 if laboratory tested, or not less than FIIC 45 if field tested.

Buildings are not soundproof. Sounds from adjacent units or other building activity are almost always audible even when the building code requirements are met.

Building Construction

Building construction floor/ceiling assemblies vary and can affect the types of sound heard from unit to unit.

  • CONCRETE: No Suspended Ceiling. A concrete slab is the only vertical separation between dwellings. Impact sound transmission is normally the major concern. Impact noise from heels or movement of chairs on floor often audible below.
  • Suspended Ceiling. Concrete slab with a gypsum board ceiling hung below at some distance. Impact noise transmission is normally the major concern.
  • WOOD: Typical construction includes joists, plywood, lightweight concrete, sound insulation, drywall and resilient channels. Higher potential for complaints because of lightweight nature of floor/ceiling assembly. Thudding from footfall almost always present. Impact noise transmission is normally the major concern.
  • Floor Surfaces

    In floor/ceiling assemblies, typical finish flooring is carpet or hard surface. The IC/FIIC code requirements are almost always met with carpet. If a carpet is going to be replaced with hard surface, there will be significantly greater impact noice transmission to the unit below.

    Role of Sound Rated Flooring Utilizing Resilient Underlayments

    In any of the buildings described, a sound rated flooring system, when properly installed, will significantly improve the IIC/FIIC when compared with a non-rated hard surface floor system. The sound rated flooring products do not have a significant effect on the STC/NIC of the floor/ceiling assembly.

    What Can An HOA Do?

    The CC&Rs of the building allow the HOA to maintain a level of airborne and impact sound isolation appropriate for the building design. We address the flooring issue below.

    • Establish a FIIC requirement for hard surface flooring. Guidelines are provided in the table below. Many factors should be considered in establishing your building requirement and the values provided below are given for guidance only.
    Type of Building Wood Construction Concrete Construction
    Government Housing 45 45
    Entry 48 50
    Standard 52 54
    High 57 60
    Luxury 62

    The requirement that is set will, most likely, require the use of a resilient underlayment within a sound rated assembly. Given the basic building construction, the achievable FIIC may be limited. The HOA should employ a qualified acoustical consultant to ensure a proper, achievable requirement is established.

    • Utilize an attorney to draft a format for the addition to the CC&Rs.
    • Require that all changes to flooring be reviewed by the HOA and meet the performance requirements. Require submission of a lab report from a nationally recognized independent acoustical testing laboratory having a similar construction to the building. Require a drawing showing where the hard surface flooring will be installed.
    • If a complaint occurs after installation, a FIIC test should be performed by an accredited acoustical laboratory approved by the HOA. The complaint should post a bond for said testing. If the test meets the building requirement, costs shall be chargeable to complainant. If the test fails, cost shall be borne by the owner of the hard surface flooring material.

    Installation

    WECU Installation Diagram

    MATERIALS CERAMIC TILE: Larger than 4″ x 4″ tile

    THIN SET (sanded): to meet ANSI A 118.4 for latex Portland Cement. All ceramic tile installation must conform to ANSI A108

    WECU: WECU Crackless for stress crack suppression only, WECU Soundless for sound control for concrete structure with suspended ceiling: WECU Soundless+ for optimum sound control for concrete and wood joist structure with or without suspended ceiling.

    MASTIC: for above grade indoor Installation use a ceramic tile mastic which conforms to ANSI A.136.1 TYPE 1 or a good quality indoor/outdoor carpet adhesive.

    APPLICATION

    1. Subfloor must be structurally sound, level and clean.

    2. Spread out mastic on subfloor with flat side of a 3/16- v-notched trowel to achieve good bond. Then, Use the notched side for a good bond to WECU.

    3. Install WECU butting seams and up to walls snugly.

    4. Roll over WECU with 75-100 Ibs roller starting in the center and rolling to the outer edge to eliminate air bubbles.

    5. Cover seams using 1″ masking tape. Once WECU is securely adhered to the subfloor proceed with the installation of selected flooring product.

    • CERAMIC TILE: Set with sanded thin set mixed with minimum acrylic latex solids of 20% to insure strong bond. Be certain to follow manufacturers recommended curing time before using floor.
    • MARBLE: Install using a medium bed mortar mixed with acrylic latex or use the mud set method.
    • HARDWOOD FLOORS: Choose floor manufacturer’s recommended adhesive for application on WECU. Do not use nails or screws.

    6. For Sound Control: Leave a 1/4″ gap between perimeter wall and flooring. Insert WECU expansion-joints or fill with acoustical sealant to prevent sound from being transmitted through the walls.

    WECU UNDER RADIANT IN-FLOOR HEAT

    When installing over WECU to the subfloor follow our installation instructions for application under ceramic tile, marble & hardwood flooring using latex modified thin set or a freeze/thaw stable adhesive. Installation instructions of the in-floor heating vary by manufacturer. WE Cork recommends that you follow the manufacturers installation instructions

    ADDITIONAL INSTRUCTIONS FOR HARDWOOD

    1. For a glue-down floor, the WECU needs to be glued to the subfloor, with the wood flooring glued to the WECU. Choose floor manufacturer’s recommended adhesive for application on WECU.

    2. For a floating-floor system, the WECU can be loose laid over the subfloor, and the wood flooring floated above that.

    3. For a nail-down floor, the WECU is loose laid over the subfloor. A double layer of 3/8″ plywood, glued and screwed together at right angles is then laid over the WECU, and the wood floor is nailed into the plywood. To preserve the integrity of the sound rated floor system, never mechanically fasten the WECU with nails, screws or staples, since this will severely diminish the acoustical performance of the system.

    WECU SILENTLY+

    1. For use under floating wood and laminate floors loosely lay the WECU Silently + over the subfloor.

    2. Where the WECU Silently + meets the wall the vapor barrier should be allowed to run up the wall and taped with a moisture resistant tape (duct tape).

    3. Butt seams snugly throughout the installation, allow the plastic to overlap.  Tape down plastic vapor barrier along seam using a moisture resistant tape (duct tape).

    4. At the finishing wall allow the plastic vapor barrier to run up the wall and then tape.  If necessary, trim back rubber portion of underlayment leaving only the plastic vapor barrier remaining prior to running up the wall.

    Characteristics

    ACOUSTICAL NATURE

    Due to 200 million air cells per cubic inch, WECU Soundless TM offers extremely efficient sound reduction, while premium sound ratings are achieved with WECU Soundless+TM. The high compression ratio of our cork quality prevents cracking of ceramic tile as well as grout.

    RESILIENCE

    Due to its resiliency and high tensile strength, WECU provides stress crack protection from existing and future subfloor stress cracks.

    EASE OF INSTALLATION

    WECU, available in rolls or sheets, is applied between the subfloor and finished flooring quickly and efficiently. No mixing, no mess, no costly ”down time” typical to trowelling methods, and no need for a backerboard under ceramic tile or marble to achieve sound reduction. Clearly an ”installers delight.”

    LOW PROFILE

    For sound control, WECU’s low height requirements (max 1/2″) and light weight make it ideal for new buildings as well as remodeling older condos with newer sound rating requirements.

    ECONOMICAL

    WECU’S fine reputation is based on the unique advantages mentioned above and LOW COST. The material itself is very inexpensive in comparison to other products used for the same purpose. The flooring can be installed directly on WECU shortly after WECU has been adhered to the subfloor. There is no added labor, material or down time – all of which equal big savings!

    PROVEN TRACK RECORD

    WECU was introduced as early as 1978 for applications under ceramic tiles and marble. In contrast to other products and many sound control methods available for similar applications, WECU has a proven flawless track record. Furthermore, its practical success is supported by grueling laboratory tests.

    WECU cannot be compared with any other cork product on the market. It is manufactured using a special process providing the unique features which have secured over 100 million square feet of failure free installations. WECU is the only cork underlayment on the market which meets two essential requirements for use under ceramic tile or marble: A Compression Ratio sufficient to avert cracking of ceramic tile and grout and Resistance to Moisture which prevents deterioration.
