are gypsum concrete, poured floor underlayments. Each product may be used for a variety of applications, and mixed in accordance with the manufacturer’s specifications at various densities between 110 and 120 pcf (1.7–1.9 kg/m

3) for a minimum 28-day

compressive strength of 1 ksi (6.9 MPa), based on testing in accordance with ASTM C472. Therma-Floor and Rapid Radiant are used in radiant heating applications in both residential and commercial construction. Level-Right is a self-leveling, cementitious poured floor underlayment that can be used to level concrete or wood subfloors. MaxxExterior Dek C-Ment

® is a cementitious underlayment

for interior and exterior use on floors supported by code-complying wood frame, steel deck and concrete construction. The shelf-life information is included in the material specification sheets distributed to all Maxxon Corporation authorized applicators.

Maxxon underlayments are used with various Maxxon sound mats (see Table 1) and other products, including Maxxon Crack Suppression Mat (CSM), Maxxon Reinforcement (MR), Maxxon Floor Primer, and Maxxon Acrylic coating as components of floor/ceiling assemblies.

4.0 INSTALLATION

Maxxon underlayments must be installed in accordance with the manufacturer’s published installation instructions. The underlayments are mixed with sand and water on the jobsite and pumped into place by Maxxon Corporation approved installers. The underlayments must have minimum density and compressive strength as specified in Section 3.0 of this report and the manufacturer’s published installation instructions or, when applicable, as specified for the fire-resistance-rated assemblies described in Section 4.1. The underlayments are installed over the sound mats listed in Table 1.

4.1 Fire-resistance-rated Floor/Ceiling Assemblies:

4.1.1 1-hour and 2-hour Fire-resistance-rated Floor/Ceiling Assemblies: The 1-hour fire-resistance-rated

floor/ceiling assemblies shown in Figures 6 through 9, and the 2-hour fire-resistance-rated floor/ceiling assembly shown in Figure 10, are based on UL designs. When using these assemblies, all details must be in accordance with the specifications contained in the UL BXUV GuideInfo. Dek C-Ment may be substituted for Dura-Cap in any of the assemblies shown in Figures 6 through 10.

ESR-2540 | Most Widely Accepted and Trusted Page 2 of 10

4.1.2 1-hour Fire-resistance-rated Floor/Ceiling Assemblies Incorporating Wood Joists: Floor

assemblies consisting of nominally 2-by-10-inch wood joists spaced 16 inches (406 mm) on center, with a 5/8-inch-thick (15.9 mm) Type X gypsum ceiling board

fastened with 1-inch (25.4 mm) Type S screws, spaced 12 inches (305 mm) on center to 1

1/2-inch-wide (38.1 mm),

No. 25 gage [0.021 inch (0.538 mm)] resilient channels, which are fastened to each joist with 1

1/4-inch (31.8 mm)

Type W or S screws, a 5/8-inch-thick (15.9 mm) plywood

subfloor and minimum 3/4-inch-thick (19.1 mm) Maxxon

underlayment topping and covered with one of the floor coverings as described in items 1 through 6 below, qualify as 1-hour fire-resistance-rated assemblies.

1. Residential high-grade carpet and cushion: 80-ounce-per-square-yard (2.7 kg/m

2), 0.97-inch (25 mm) pile

carpet and 9/16-inch (14.3 mm) solid urethane-foam

pad with reflective silver scrim with or without 3-inch-thick (76 mm) fiberglass insulation in the ceiling cavity.

2. Residential medium-grade carpet and cushion: 50-ounce-per-square-yard (1.7 kg/m

2), 0.59-inch

(15 mm) pile carpet and 1/2-inch (12.7 mm)

marbleized urethane-foam pad with clear scrim with 3-inch-thick (76 mm) fiberglass insulation in the ceiling cavity.

3. Residential low-grade carpet and cushion: 24-ounce-per-square-yard (0.814 kg/m

2), 0.25-inch (6.4 mm)

pile carpet and 9/16-inch (14.3 mm) marbleized foam

with clear scrim with or without 3-inch-thick (76 mm) fiberglass insulation in the ceiling cavity.

4. Commercial high-grade carpet and cushion: 58-ounce-per-square-yard (1.97 kg/m

2), 0.437-inch

(11 mm) pile carpet and 0.265-inch (6.7 mm), 5 pcf (80 kg/m

2), 0.203-inch (5.2 mm) pile

carpet and 0.25-inch (6.4 mm) solid yellow urethane pad with 3-inch-thick (76 mm) fiberglass insulation in the ceiling cavity.

4.2 Sound-transmission-rated Floor/ceiling Assemblies:

The assemblies pictured in Figures 1 through 5, which feature simplified descriptions of the fire-resistance-rated assemblies detailed in Figures 6 through 10, respectively, have a minimum Sound Transmission Class (STC) of 50 and a minimum Impact Isolation Class (IIC) of 50. The manufacturer-specified minimum poured underlayment depth over sound mats is as described in Table 1 for sound rated assemblies. The sound mat shown in Figures 1 through 5 can be removed from the assembly and have the assembly still maintain its sound rating, if carpet and pad are utilized as the floor covering materials. Table 1 identifies the minimum thickness of the underlayment needed if the sound mat is removed.

The assemblies described in Section 4.1.2 are sound-transmission-rated assemblies with a minimum STC of 50 and a minimum IIC of 50.

Care must be taken during the selection and installation of all building components to achieve the stated sound-transmission ratings. Sound flanking paths such as penetrations or openings in construction assemblies must be sealed, lined, insulated, or otherwise treated to maintain the required ratings in accordance with Section 1207 of the IBC or Appendix K of the IRC, as applicable.

4.3 Alternate One-hour Fire-resistance-rated Construction to Double Wood Floor Assembly Shown in 2015 and 2012 IBC Table 721.1(3) (2009 IBC Table 720.1(3)) (Footnote m):

As an alternate to the double wood floor, 5/8-inch-thick

(15.9 mm) plywood subfloor covered with 3/4-inch-thick

(19.1 mm) underlayment, with one coat of latex bonder applied to the subfloor prior to installation of the underlayment, is acceptable. The latex bonder liquid latex, 48-50 percent solids diluted 1:1 with water, is applied at a rate of 300 square feet per gallon (7.4 m

2/L).

Note: Since Footnote n of IBC Table 721.1(3) [2009 IBC Table 720.1(3)] applies to the assembly described in Footnote m of IBC Table 721.1(3) [2009 IBC Table 720.1(3)], they also apply to the alternate assembly described above.

5.2 Installation is by applicators authorized by Maxxon Corporation.

5.3 For the floor coverings specified in Section 4.1, compliance with the applicable requirements of IBC Section 804 is outside the scope of this report.

5.4 Use of Maxxon underlayments as components of fire classified roof coverings is outside the scope of this report.
