Sound Absorption Coefficients(as)
The Sound Absorption Coefficient is ideally defined as a fraction of the randomly incident sound power absorbed by material. The greater the coefficient, the greater the sound absorption.
SAA The Sound Absorption Average (SAA) is a single number rating obtained by taking the arithmetical average of the absorption coefficients at 250, 500, 1000, 2000 Hz rounded to nearest multiple of 0.05.
Wall Insulation Between Roomsacoubatt® is ideal for reduction of airborne sound transmission between rooms through separating walls.
STC The STC stands for Sound Transmission Class is a single number that represents the performance of the soundproofing through the air (Airborne) of walls, ceilings, doors, or by a laboratory test (standard ASTM E90-09). The values in the range of 125-4000 Hz were calculated (according to ASTM E 413-87) In summary, the higher the STC is well soundproofed.
Excellent Thermal Insulationacoubatt® is also an ideal thermal insulation material for your interior walls and ceilings in buildings and home to help keep the interiors cooler in summer and warmer in winter. This helps with saving energy costs by maintaining temperature inside the building.
What is the R value of insulation
An insulating material's resistance to conductive heat flow is measured or rated in terms of its thermal resistance or R-value -the higher the R-value, the greater the insulating effectiveness. The R-value depends on the type of insulation, its thickness, and its density.
R-Value,
Thermal resistance,
unit of : m2.K/W or ft2.h.oF/Btu
K-Value,
Thermal conductivity
unit of : W/m.K or Btu.in/ft2.h.oF
