Aquaflex Eliminates the Need for an Acoustic Underlayment
Aquaflex Performs to Attenuate Sound!
Performance on par with many noise reduction underlayments
Results are in on the acoustic studies conducted by Intertek. The testing was conducted on a 6” concrete slab w/ ceiling assembly. We ran both the ASTM E90 (STC) and ASTM E492 (IIC) test protocols. TAJ provided the Select Planks/Royal Maple 3mm, 6” x 36” plank for testing. Our results were surprising considering we used the CBD trowel which is a 9/64” U-notch spread compared to typical LVT adhesives using a 1/32” sq notch spread (almost 2X the glue). Our results prove that Aquaflex adhesive, by itself, will attenuate sound in both ASTM protocols comparable to systems of acoustical underlayment with adhesive. More importantly our values exceed the IBC Code 2006 for noise abatement.
Sound Transmission Class (STC) is an ASTM E90 measurement of the amount of sound transmitted through the floor. (Like the noise from an upstairs TV)
Impact Insulation Class (IIC) is an ASTM E492 measurement of the amount of sound transferred by impact to the floor. (Like the sound from high heels)
|Type of Sound Generated||STC required to make inaudible|
Legal and Practical Code Requirements
Section 1207 of International Building Code 2006 states that separation between dwelling units and between dwelling units and public and service areas must achieve STC 50 and IIC 50 for both air and structure-borne sound.
