Decibel measurements are taken at various specified frequencies in the lower chamber. Both tests involve a standardized noise making apparatus in an upper chamber and a sound measuring system in a lower chamber. STC evaluates the ability of a specific construction assembly to reduce airborne sounds, such as voices, stereo IIC tests the ability to block impact sound by measuring the resistance to transmission of impact noise or structure-borne noise (simulating footfalls, objects dropped on the floor, etc.).
#Underlayment sound code#
There are two types of laboratory sound tests performed in a controlled environment recognized by the International Building Code (IBC) for sound vibration that travels from one living area to another: Impact Insulation Class (IIC) and Sound Transmission Class (STC). The following is an effort to explain those sound test methods and their results. The testing methods utilized in North America for sound evaluations and comparisons, and the values they generate, can be somewhat confusing and even, perhaps, misleading. When evaluating flooring underlayment for sound deadening characteristics acoustical consultants, architects/specifiers and others rely on sound testing to define the performance of a floor/ceiling assemblies and determine how well they insulate against noise created by impact and by airborne vibration. Sound insulation between living areas in multi-family or single-family dwellings, is an important issue for the floor covering industry. Use with laminate, hardwood, and engineered wood floor systems and most ceramic and stone tile installations to reduce noise transmission in High Rises, Condominiums, Schools, Multi-family homes, Hospitals, Apartment Buildings and Theaters *Insulates ceramic and laminate floors without that “springy” feeling of cork or foam. *Very low Volatile Organic Compounds (VOCs) *Resists compression while offering superior underfoot comfort. *Simple, fast and cost-efficient installation *Delivers years of reliable sound control In addition, Rubber Sound Control Underlayment cushions and insulates ceramic and laminate floors without that artificial “springy” feeling.Īvailable in 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 12mm & 15mm thicknesses
#Underlayment sound crack#
Rubber Sound Control Underlayment acts as a crack suppression membrane, preventing cracks as large as 1/4” from damaging the flooring above. Rubber Sound Control Underlayment not only contributes to energy conservation, it qualifies for LEED (Leadership in Energy and Environmental design) points under Green Building Council Certifications, and is California Department of Public Health (CDPH) and the Collaborative for High Performance Schools (CHPS) certified.Ĭoncrete floors are prone to cracking. Used in schools, hospitals, hotels and condominiums, Rubber Sound Control Underlayment has very low VOCs and can be installed under most types of grouted, glued and floating floors (no adhesive required for floating floors), including ceramic tile, stone, and engineered woods. Not only does Rubber Sound Control Underlayment prevent the annoying sound transmission of foot traffic to the floors below, it also effectively deadens the transmission of interior noise, such as from stereos and voices. Unlike natural cork, recycled rubber remains permanently resilient and will not become brittle with exposure to air.
Rubber Sound Control Underlayment is sustainable, recycled rubber underlayment provides optimal sound reduction while remaining impervious to the elements. Quiet Sound Acoustical Underlayment is the premium solution for noise transmission in all kinds of multi-story buildings. Floor Preparation & Maintenance Products.
