Insulayment Product Information



Installation Instructions

  1. Conditioning: The underlayment and adhesives must be conditioned at 70 degrees Fahrenheit with the relative humidity between 25 and 65% for at least 24 hrs before and 72 hrs after installation.
  2. Approved Surfaces for Applications:
    1. For Glued Down Engineered and Solid Wood Floors: Plywood, hardboard underlayment, association grade particleboard, concrete above grade in the absence of excessive moisture and/or excessive alkali, and well-bonded VCT* and sheet vinyl* (non-embossed and non-cushioned). Sub-floor must meet NWFA (National Hardwood Flooring Association) and local building code standards for quality, thickness, and maximum deflection.
    2. For Mechanically Fastened Solid or Engineered Wood Floors: Hardboard underlayment, concrete backer board, plywood or wood. Sub-floor must meet NWFA (National Hardwood Flooring Association) and local building code standards for quality, thickness, and maximum deflection.
    3. For 8" or larger Ceramic or Porcelain Tile (not designed for natural stone): All installations must comply with the American National Standards ANSI A-108 unless otherwise noted. Plywood, concrete backer board, concrete (with moisture vapor emission rate of less than 5lbs/1000sqft/24hrs and pH less than 9), and well bonded VCT or Sheet Vinyl* (non-embossed and non-cushioned). All sub-floor structures must meet or exceed ANSI standards for quality, thickness, and maximum deflection. The sub-floor must also comply with local building codes.
    4. Unsuitable substrates for ceramic tile: The following is a list of sub-floor surfaces not suitable for ceramic tile installations: masonite, all grades of lauan plywood, expanded polystyrene (styrofoam) insulation board, particle board, paneling, stripwood floors, grease-saturated concrete, vertically displaced concrete, sheathing and/or other oriented strand board, pressure-treated plywood, fire-resistant plywood, curing compounds, felt paper and scribing felt.

    *Sheet Vinyl or VCT:

    • If at all possible, remove the old sheet vinyl or VCT. It is almost always a better choice to install over the original sub-floor surface. Make sure you comply with all codes and use safe work practices as published by the Resilient Floorcovering Institute when removing vinyl floor coverings and adhesives.
    • Wood underlayments that are structurally suitable for vinyl may not be sutable for ceramic tile or wood floors. Verify that wood floor assembly meets requirements for ceramic tile installations under Tile Council of America (TCA) and America National Standards Institute (ANSI) guidelines.
    • The vinyl must be well adhered to the underlayment throughout the entire floor.
    • Make sure the mortar or adhesive is approved for use on vinyl.
    • Allow additional drying or "set" time (at least twice the manufacturer's recommendation) for the setting material used in each phase of the installation.
  3. Surface preparation: Floor must be clean, smooth, dry and free of foreign matter that would interfere with a good bond. Fill all cracks and depressions with a suitable floor patch. If adhesive removal chemicals have been used, make sure the floor has been properly rinsed and all chemical residues are removed. All existing cracks in excess of 1/16" must be repaired with appropriate materials.
  4. Moisture: All sub-floor assemblies should be tested for moisture vapor emission rates by utilizing anhydrous calcium chloride test kits for concrete or a certified moisture meter for wood. Do not install flooring material when in excess of flooring manufacturers recommendations for moisture vapor emissions.

    4. Dampen, but do not saturate, the concrete floor and the bottom side of the pre-cut Insulayment pad with a sponge or a mist sprayer.
    5. Key the thin-set mortar into the sub-floor with the flat side of the trowel then comb it with the notched side using a left to right motion.
    6. Apply the thin-set mortar only as far ahead as will allow installation of the Insulayment prior to the mortar beginning to set or "skin over".
    7. Unroll the Insulayment into the thin-set.
    8. Immediately (within 10 minutes) roll the Insulayment with a 75lb roller in diagonal directions.
    9. Do not walk on the rolled areas for at least 16hrs. Allowing traffic on the installed Insulayment prior to full set may cause indentations resulting in weak areas and hollow spots.
    10. Make sure there is at least 95% transfer of the thin-set.
    11. Seams should be butted together, leaving no gaps or overlaps.
    12. Allow the Insulayment to set for at least 16 hrs.

    3. Use Latex Portland cement mortar that conforms to test requirements found in ANSI A118.4 or 118.11.
    4. Key the thin-set into the Insulayment with the flat side of the trowel and then comb it with the notched side using a left to right motion.
    5. Press the tile into the thin-set using a front to back motion perpendicular to the spread of the thin-set for maximum transfer of the thinset onto the tile.
    6. Mortar average coverage per tile shall comply with ANSI A108.5.3.3.3, which requires, 1) the backbuttering of each tile, 2) at least 95% thin-set coverage on each tile.
    7. Minimum grout joint width is 3/16".
    8. Allow no traffic on the tiled surface for at least 16hrs.
    9. Use epoxy grout as per manufacturers instructions.

    Insulayment? is a unique, earth-friendly, insulating underlayment that helps absorb impact sound so it won't transfer to lower level rooms; suppresses the effect of concrete sub-floor cracking to protect flooring from potential plank gapping; and insulates floors to help keep them warm in the winter and cool in the summer. The 0.11" thickness of Insulayment also helps smooth out imperfections in substrates prior to the installation of a hard-surface floor covering.

    CERTIFIED RECYCLED AND HEALTHIER INDOOR AIR QIJALITY

    ADVANTAGES

    • Sound absorption.

      Insulayment's filaments are randomly air-laid creating a capillary affect to the floor, absorb sound, and help make laminate floors sound more like real wood.

      Field Impact Insulation Class (F-IIC) = 60
      Impact Insulation Class (IIC) = 52
      Sound Transmission Class (STC) = 53

    • Smoothing out minor sub-floor imperfections.

      Insulayment is firm enough (density = 18.9 lbs/ft3; compression resistance @ 25% = 23.2 psi) to support the overlaying floor, but flexible enough to form around sub-floor surface roughness that may otherwise cause laminate panels to "rock" or lay unevenly.

    • Adding insulation value.

      Insulayment will add a thermal "break" to the flooring assembly with an r-value of approximately .50.

    • Approved for use over in-floor heat systems.

      The patented process used to make Insulayment creates a three dimensional fiber matrix that allows heat to permeat evenly while helping to protect the floor covering material from thermal shock.

    • Multipurpose.

      Insulayment can be used under all types of industry approved subfloors.

    ENVIRONMENTAL ATTRIBUTES

    • Insulayment is certified by Scientific Certifications Systems (SCS) to contain 100% post industrial/pre-consumer fibers. Insulayment is LEED? compliant and will contribute to MRc4.1-4.2 credits.

    • Passed Section 01350 for CHPS and Standard Office

    • CHPS-listed product

    • Makes contributes to LEED MR Credit 4.1-4.2

    LIMITATIONS

    • All sub-floor assemblies should be tested for moisture vapor emission rates by utilizing anhydrous calcium chloride test kits for concrete or a certified moisture meter for wood. Do not install flooring material when in excess of flooring manufacturers recommendations for moisture vapor emissions.
