Quiet Walk Underlayment
Quiet walk is a unique, earth-friendly, insulating laminate and floating wood floor underlayment that smoothes out little subfloor imperfections while quieting impact sound and floor to ceiling noise. Quiet walk dampens ambient sound in the room it's installed in and helps minimize impact and airborne sound from traveling into the room below. Quietwalk's unique manufacturing process and recycled fiber composition allows it to dissipate moisture from both below and above, while retaining it's exceptional compression resistance over lifetime of the floor.
• Increased absorbency and dissipation of moisture with added Super Absorbent Polymer (SAP) that enhances moisture carrying capacity
• Increased moisture barrier strength
•Approved for use over radiant heated floors
• QuietWalk filaments are randomly air-laid creating a capillary effect to cushion the floor, absorb sound, and help make laminate floors sound more like real wood.
• Sound Transmission Class (STC) = 54
• Impact Insulation Class (IIC) = 58
• Field Impact Insulation Class (F-IIC) = 60
• When installed properly, QuietWalk® can wick sub-floor or incidental perimeter moisture and disperse it through the pad.
• Moderate amounts of moisture will eventually dissipate over time by perimeter or sub-floor evaporation, provided the source of water such as a leak is stopped.
Smoothes out minor sub-floor imperfections
• QuietWalk® is firm enough (density=13.3lbs/ft^3; compression resistance @ 25%=9.5psi) 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.
Adds insulation value
• QuietWalk® will add an R-Value of .50 to the floor system.
• QuietWalk® is ideally priced as a quality upgrade from polyethylene or polystyrene film and is less than 1/2 the cost of either cork or rubber underlayment with similar sound numbers.
Made From Recycled Materials
• QuietWalk® is a “green” product, constructed (over 95%) with postindustrial/pre-consumer fibers, materials that may otherwise have been land filled.
• Synthetic fibers by their composition do not support the growth of bacteria and fungus.
• The high temperature manufacturing process used to produce Quiet Walk will eliminate live organisms.
•An EPA registered anti-microbial is incorporated in Quietwalk to control mold, meldow or bacteria on the treated product.
STC (Sound Transmission Class) Ratings
The term STC refers to the single figure of evaluation used to quantify the transmission of airborne sounds through building elements, such as a wall or floor systems. These types of sounds would be the equivalent of voices, music, radio or television audio in the context of a multi-family building. The term STC translates to Sound Transmission Class and is measured and stated in accordance ASTM Standard number C634 and tested via the test methodology of ASTM Test Methods E 90, E 336 and E 596. When done in an accredited test laboratory, these values are stated as a number to the right of the initials STC. When done in the “Field”, using ASTM Method E 336, these values are designated by the initials FSTC to the left of the numeric value.
STC values are in a large part influenced by solid mass of the structure, but are also somewhat dependent on isolation and resilience within the structure.
IIC (Impact Insulation Class) Ratings
The term IIC refers to the statistical measurement standards used to quantify the transmission of impact sound energy through a floor/ceiling assembly system. These types of sounds would be the equivalent of foot traffic, dropped articles or furniture moving in the context of a multi-family building. The term IIC translates to Impact Isolation Class and is measured and stated in accordance to ASTM Standard number C634 and tested via the test methodology of ASTM Test Methods E90, C423, E 548,
E 717 and E 989. In addition, a new test protocol for concrete sub-floors has been introduced under ASTM E 2179-01. When done in an accredited test laboratory these values are stated as a number to the right of the initials IIC. When done in the “Field”, using ASTM Method E-1007, these values are designated by the initials FIIC to the left of the numeric value.
IIC values are not heavily influenced by the presence of solid mass in the structure.
IIC values are dependent on the presence of a resilient material somewhere in the assembly to isolate and absorb the sonic energy created by impacts.
STC and IIC Ratings and Building Codes
In multi-family construction, in most jurisdictions, there are minimum IIC and STC values which the floor/ceiling assembly must achieve to meet the building code standards. Most common is the U.B.C. Uniform Building Code or I.B.C. International Building Code, which calls for minimum values of IIC 50 and STC 50. Some states, municipalities and counties have different building code standards, but the U.B.C. and I. B.C. codes are by far the most common. Consult your local Building Department for the exact code standards applicable in your area.
In addition to the building code standards, some condominium developers and condo homeowners associations have their own minimum standards written into their Covenants, Conditions and Restrictions (CC&R’s), which are often more stringent than the building code in that given jurisdiction. It is wise to consult your condo association in regard to their CC&R standards for the required IIC and STC values before installing hard surface flooring materials in your unit.
1) Be sure the sub floor surface is clean and dry.
2) Roll QuietWalk® underlayment over the sub floor with the vapor barrier film (blue side) facing up.
3) The perimeter edges of QuietWalk® need to be 1/2 to 3/4 inches away from the wall.
4) Seams need to be butted together flush, do not overlap the pad. Tape the seams with water and tear resistant, utility-grade, poly-coated cloth backed tape that has a very aggressive adhesive (duct tape).
5) Install laminate flooring according to the manufacturer’s installation instructions.
