Part III  Execution

3.1 Surface Condition

  • Sub floor shall be structurally sound. Deflection shall not exceed 1/360 of the span, including live and dead loads.
  • Sub floor shall be dry and free of debris.

3.2 Installation

  • Perimeter Isolation Strip:
    • Install Enkasonic Perimeter ISO at the perimeter of the entire sub floor (including door frames), and around any protrusions through the installation. This procedure isolates the Enkasonic floor system from the walls in order to create an acoustical break which will minimize the transmission of sound laterally from the "floating floor" to the walls. Also, the perimeter isolation material provides space for possible expansion of the finished flooring.
    • Adhere the foam perimeter isolation strip to the wall with construction adhesive applied as close as possible to the top of the foam strip.
  • Enkasonic Sound Control Matting:
    • Lay the Enkasonic directly over the sub floor (or waterproofing membrane, if applicable) with the black mesh down, white fabric side up. Push the Enkasonic up tightly to the isolation barrier previously installed around the perimeter of the floor.
    • If hardwood flooring and plywood floating slab are to be used, place a layer of roofing felt on the sub floor prior to the Enkasonic.
    • If the waterproofing membrane is mopped-on, put a layer of roofing felt over the membrane before installation of the Enkasonic.
    • Butt adjoining edges of the black Enkasonic mesh together. Then tape [Duct Tape or 2" (5 cm) wide Cellophane Tape] the 3" (7.5 cm) wide longitudinal fabric overlap snug to the adjoining Enkasonic strip. The taping procedure seals the overlap seams and keeps any residual material from getting into the Enkasonic mesh. Tape seam at intersection of Perimeter Isolation and Enkasonic.
    • Enkasonic is free-floating. Do not attach it to the sub floor with nails, screws, staples, glue or any type of attachment.

    Specifier Note: It is necessary to install an overlay over the Enkasonic to receive and support the finished flooring. The overlay varies with the type of finish flooring. The overlays are: 1¼" (3.2 cm) mortar bed, 7/16" (11 mm) WonderBoard®, ½" (4 cm) lightweight Concrete [1800 PSI (12.4 MPa)], 1½" (4 cm) Gypsum [2000 PSI minimum (13.8 MPa)], or two layers of minimum ½“ plywood. Specific installation details are described in our installation bulletins.

  • Finish Flooring
    • After the finished flooring is installed, trim the perimeter isolation barrier to 1/4" (6.5 cm) below the finished flooring. Fill the groove with a bead of acoustical or elastomeric sealant. Do not allow hard grout to come in contact with the wall. If the floor is carpet or vinyl, trim the perimeter isolation barrier flush with the surface before the finished flooring is installed. Shim the molding to 1/16” to 1/32” (1.6 to 0.8 mm) above the finished flooring preventing a transmission path for sound between the finished floor and wall.
    • If a flat base is adhered to the wall, space it 1/8" (3.2 mm) up from the tile surface, and run a bead of acoustical sealant into the void.
    • If a cove base is used, fill the joint between the last course of floor tile and the base with acoustical sealant.
