Ultratouch Acoustic Ratings

Controlling sound and noise transmission through walls, ceilings and floors can be a challenge in designing and building a structure. Sound Attenuation is a complex interaction between building systems and materials that is measured two ways. Sound buffering is tested through Sound Transmission Class (STC) and Noise Reduction Coefficients (NRC). UltraTouch achieves high values for both measures that is unmatched by other materials. The isolation and control of sound waves by UltraTouch's three-dimensional infrastructure will not disappoint you!

Sound Buffering - The Whole Picture

UltraTouch adds mass (weight, thickness and density) to a wall eliminating the need for excessively complex wall systems for sound attenuation and thermal performance.

Sound Absorbed: NRC

UltraTouch has an extremely high Noise Reduction Coefficient (NRC) which effectively reduces airborne sounds, such as traffic, airplanes, radio, television, even conversation. The natural fibers used in UltraTouch contain superb sound absorbing qualities. Its patented manufacturing process creates a three dimensional infrastructure that traps, isolates and controls sound waves. The result is a quiet, comfortable barrier between rooms, walls and floors.

UltraTouch Noise Reduction Coefficient of 115% is exceptional. The value of 115% accounts for the laboratory setting where the 3 dimensional sample of UltraTouch, in the attenuation chamber, was measured at 250-500-1000-2000hz. All noise was absorbed.

Sound through Wall Systems: STC

Use of Sound Transmission Class (STC) ratings, the generally accepted rating measure, reflects ratings on wall systems in laboratory testing. When making comparisons between products, consider this:

Compare Apples to Apples: Equivalent wall systems of product material should be used for evaluation of STC (Wood studs vs. metal studs, thickness of drywall, and use of resilient clips all effect performance.) Equal wall systems, with insulation of equal R-values and thickness, (fiberglass vs. cellulose vs. cotton) provide an accurate comparison.
When any wall system claims to achieve the optimal STC, consider density and how many potential breaches these systems have in the field during execution of construction. Minimizing these early on through proper sealing will yield better acoustical performance. Less dense insulating materials do not buffer sound as well, nor do they insulate as well.
Adding mass and air separation techniques will always increase STC, regardless of the insulation type selected

NRC - Noise Reduction Coefficient	STC - Sound Transmission Class
A Standard	A Code
Noise buildup within a space	Noise moving between spaces
NRC increased capabilities does not stop noise from passing though (STC)	STC increase will not change reverberence or reflection effect within space (NRC)
A number index, expressed in percentage, rating absorption properties of a material:100% - all noise absorbed	A number indicating transmission loss of a system (wall, ceiling etc.) Expressed as a scale: 0 - Poor 56 - Excellent
Products: individual sample is measured as a unit	Products: Components measured together as one system
Cause for build up of Noise: - Reverberence: large space with reflective materials such as drywall, glass, tile -Focus Reflections: domes, peaks concave surfaces	Cause for transmission of Noise: - Lack of barrier
Solution: Provide absorptive materials to reduce reverberation & limit reflections	Solution: Provide a barrier of adequate construction. Add mass, air space, cavity insulation. Control weak points, seal joints and penetrations. Weakest point must be controlled.
