- Buy 1000 for $2.39 each and save 4%
Made up of over 100 millionprism shaped cells per cubic inch, each one filled with air, cork inhibits the conduction of temperature and sound. AcoustiCork underlayment reduce impact noise and stress crack protection underneath most hardsurface flooring products and it's known to be a great asset for applications such as multi-level condominiums, office spaces, meuseums and places of worship. 12mm cork underlayment designed to meet building code and condominium association requirements when the floor/ceiling assembly system is ceramic, natural stone or wood with a suspended ceiling.
Suberin, an inherent substance of cork is a natural insect repellent. Even termites are kept away. Cork is anti-microbial and is resistant to mold and mildew. Cork is also anti alergie product.

Composite wood or agri-fiber products must contain no added urea-formaldehyde resins.
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.
