1 Sound Control Solutions in Floor/Ceiling Assemblies

2 Controlling sound becomes more important every day. At SAMfloors, it is our mission to provide elegant, functional sound control solutions to meet the rapidly growing need for personal health, welfare and privacy.

3 SF Products SAMfloors SF Sound Control Products feature a lightweight monolithic, closed-cell composite technology that combines ease of use and superior performance, with lower cost.

4 70 IIC 67 STC With a Delta IIC as high as 23 and IIC and STC ratings that exceed UBC/IBC requirements by more than 40%, meeting the needs has never been easier. Actual acoustical performance is dependent on system design and construction of the floor/ceiling assembly. Performance data based on third party independent laboratory testing and typical properties. For values related to individual assemblies, please refer to the respective product information sheets.

5 Sound Control Basics How is sound transmitted in floor/ceiling assemblies?

6 Attenuation Sound Diminishes Through Attenuation of the Sound Wave. Attenuation is the Combination of Absorption and Scattering /Diffusion.

7 Absorption Absorption- The process by which a material, structure, or object takes in sound energy when sound waves are encountered. Part of the absorbed energy is transformed into heat and part is transmitted through the absorbing body. The sound energy transformed into heat is said to have been 'lost'.

8 Diffusion Diffusion (Scattering)- Sound will move laterally after it crosses into a resilient layer.

9 Sound Control Basics How is sound measured in floor/ceiling assemblies?

10 Sound Transmission Class (STC) STC tests the ability of a specific construction assembly to reduce airborne sounds, such as voices, stereo systems, and TV (ASTM E 90). It should be noted that this test takes all components of a floor / ceiling assembly into consideration, such as framing type, insulation, ceiling components, etc. A rating of 50 STC or above will satisfy the International Building Code.

11 Impact Insulation Class (IIC) 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.) (ASTM E 492/E 989). Similar to STC, the IIC performance values include all components, not just sound underlayment, in their calculation. A rating of 50 IIC or above will satisfy the International Building Code.

12 Delta Impact Insulation Class (Delta IIC) The Delta IIC is the only true standard for comparing the performance of competitive sound underlayment materials. Another test that more directly evaluates impact sound of underlayment materials is ASTM E-2179, also known as the Delta test. This test consists of two IIC tests conducted over the same 6 concrete slab. One test is over the bare concrete slab (no flooring materials) and the other is over the concrete slab with floor covering and sound underlayment included. The measured IIC values are compared to the reference floor levels defined in the standard and adjusted to provide the IIC the covering would produce on the reference concrete floor. This test is important as it does not take any other components (insulation, ceiling, etc) of a floor / ceiling assembly into consideration, but instead, only measures the effect of the sound underlayment.

13 Sound Control Basics Traditionally, what materials have been used to control sound?

14 Rubber Utilizes increased mass/density to create sound transmission loss. Heavy Expensive Difficult to cut Not odorless-emissions Requires thicker layers in order to increase performance

15 Entangled Mesh Utilizes airspace to create sound transmission loss. Not monolithic More expensive Sandwich configuration Subject to compression Challenging to install Can not receive direct application of floor goods

16 Sound Control Basics What is the new technology for controlling sound?

17 Based on a Proprietary Composite Technology, the SF sound underlayment delivers the optimal combination of Air, Mass and Density.

18 SF Sound Underlayment Monolithic, Closed Cell Composite Technology. The SF sound underlayment is scientifically designed to deliver optimal results in a low-profile layer, while effectively creating performance values that exceed code requirements by as much as 40%.

19 SAMfloors In Action v During Absorption and Diffusion, SF 300 closed cell technology captures and isolates the sound with each cell acting as a sound absorber.

20 Code Compliant With IIC ratings as high as 70 db, SF Products meet or exceed UBC/IBC code requirements for sound control by more than 40%. Science In A Roll The optimal combination of materials created by scientists to address society s growing need for health, welfare and privacy. Fire Rated Resistant to moisture, mold and bacteria Achieves a Class A rating when tested in accordance with ASTM E For use in most UL fire rated assemblies. SAMfloors products are impervious to mildew, mold, rot, and bacteria, as well as resistant to moisture, chemicals, and grease.

21 High or Low Frequencies Whether you are looking for basic comfort or want to address high and low frequency impact noise, we have a product solution to fit your needs. Lightweight Sustainable Low Profile Each 1000 Sq Ft roll weighs in at 32lbs. That s 40% more mat and 10lbs less per roll than Entangled Mesh, and 10X lighter than Rubber. Manufactured with 100% recyclable materials. Our Eco-options contain over 50% recycled raw materials. SF Products are non-toxic and odorless. SAMfloors ⅛ low profile mat is easily rolled out, fitted, and placed onto a surface. This easy to cut mat has multiple uses.

22 Direct Attachment of floor goods SF Sound Underlayment allows for direct attachment of a wide variety of floor coverings including engineered wood, laminate, hardwood and other finishes.
